| CVE-2020-29573 | 3 Gnu, Netapp, Redhat | 9 Glibc, Cloud Backup, Solidfire Baseboard Management Controller and 6 more | 2024-11-21 | 7.5 High |
| sysdeps/i386/ldbl2mpn.c in the GNU C Library (aka glibc or libc6) before 2.23 on x86 targets has a stack-based buffer overflow if the input to any of the printf family of functions is an 80-bit long double with a non-canonical bit pattern, as seen when passing a \x00\x04\x00\x00\x00\x00\x00\x00\x00\x04 value to sprintf. NOTE: the issue does not affect glibc by default in 2016 or later (i.e., 2.23 or later) because of commits made in 2015 for inlining of C99 math functions through use of GCC built-ins. In other words, the reference to 2.23 is intentional despite the mention of "Fixed for glibc 2.33" in the 26649 reference. | ||||
| CVE-2020-28374 | 4 Debian, Fedoraproject, Linux and 1 more | 9 Debian Linux, Fedora, Linux Kernel and 6 more | 2024-11-21 | 8.1 High |
| In drivers/target/target_core_xcopy.c in the Linux kernel before 5.10.7, insufficient identifier checking in the LIO SCSI target code can be used by remote attackers to read or write files via directory traversal in an XCOPY request, aka CID-2896c93811e3. For example, an attack can occur over a network if the attacker has access to one iSCSI LUN. The attacker gains control over file access because I/O operations are proxied via an attacker-selected backstore. | ||||
| CVE-2020-27779 | 4 Fedoraproject, Gnu, Netapp and 1 more | 12 Fedora, Grub2, Ontap Select Deploy Administration Utility and 9 more | 2024-11-21 | 7.5 High |
| A flaw was found in grub2 in versions prior to 2.06. The cutmem command does not honor secure boot locking allowing an privileged attacker to remove address ranges from memory creating an opportunity to circumvent SecureBoot protections after proper triage about grub's memory layout. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. | ||||
| CVE-2020-27749 | 4 Fedoraproject, Gnu, Netapp and 1 more | 12 Fedora, Grub2, Ontap Select Deploy Administration Utility and 9 more | 2024-11-21 | 6.7 Medium |
| A flaw was found in grub2 in versions prior to 2.06. Variable names present are expanded in the supplied command line into their corresponding variable contents, using a 1kB stack buffer for temporary storage, without sufficient bounds checking. If the function is called with a command line that references a variable with a sufficiently large payload, it is possible to overflow the stack buffer, corrupt the stack frame and control execution which could also circumvent Secure Boot protections. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. | ||||
| CVE-2020-25705 | 2 Linux, Redhat | 7 Linux Kernel, Enterprise Linux, Rhel Aus and 4 more | 2024-11-21 | 7.4 High |
| A flaw in ICMP packets in the Linux kernel may allow an attacker to quickly scan open UDP ports. This flaw allows an off-path remote attacker to effectively bypass source port UDP randomization. Software that relies on UDP source port randomization are indirectly affected as well on the Linux Based Products (RUGGEDCOM RM1224: All versions between v5.0 and v6.4, SCALANCE M-800: All versions between v5.0 and v6.4, SCALANCE S615: All versions between v5.0 and v6.4, SCALANCE SC-600: All versions prior to v2.1.3, SCALANCE W1750D: v8.3.0.1, v8.6.0, and v8.7.0, SIMATIC Cloud Connect 7: All versions, SIMATIC MV500 Family: All versions, SIMATIC NET CP 1243-1 (incl.

| CVE-2020-25686 | 5 Arista, Debian, Fedoraproject and 2 more | 10 Eos, Debian Linux, Fedora and 7 more | 2024-11-21 | 3.7 Low |
| A flaw was found in dnsmasq before version 2.83. When receiving a query, dnsmasq does not check for an existing pending request for the same name and forwards a new request. By default, a maximum of 150 pending queries can be sent to upstream servers, so there can be at most 150 queries for the same name. This flaw allows an off-path attacker on the network to substantially reduce the number of attempts that it would have to perform to forge a reply and have it accepted by dnsmasq. This issue is mentioned in the "Birthday Attacks" section of RFC5452. If chained with CVE-2020-25684, the attack complexity of a successful attack is reduced. The highest threat from this vulnerability is to data integrity. | ||||
| CVE-2020-25685 | 5 Arista, Debian, Fedoraproject and 2 more | 10 Eos, Debian Linux, Fedora and 7 more | 2024-11-21 | 3.7 Low |
| A flaw was found in dnsmasq before version 2.83. When getting a reply from a forwarded query, dnsmasq checks in forward.c:reply_query(), which is the forwarded query that matches the reply, by only using a weak hash of the query name. Due to the weak hash (CRC32 when dnsmasq is compiled without DNSSEC, SHA-1 when it is) this flaw allows an off-path attacker to find several different domains all having the same hash, substantially reducing the number of attempts they would have to perform to forge a reply and get it accepted by dnsmasq. This is in contrast with RFC5452, which specifies that the query name is one of the attributes of a query that must be used to match a reply. This flaw could be abused to perform a DNS Cache Poisoning attack. If chained with CVE-2020-25684 the attack complexity of a successful attack is reduced. The highest threat from this vulnerability is to data integrity. | ||||
| CVE-2020-25684 | 5 Arista, Debian, Fedoraproject and 2 more | 10 Eos, Debian Linux, Fedora and 7 more | 2024-11-21 | 3.7 Low |
| A flaw was found in dnsmasq before version 2.83. When getting a reply from a forwarded query, dnsmasq checks in the forward.c:reply_query() if the reply destination address/port is used by the pending forwarded queries. However, it does not use the address/port to retrieve the exact forwarded query, substantially reducing the number of attempts an attacker on the network would have to perform to forge a reply and get it accepted by dnsmasq. This issue contrasts with RFC5452, which specifies a query's attributes that all must be used to match a reply. This flaw allows an attacker to perform a DNS Cache Poisoning attack. If chained with CVE-2020-25685 or CVE-2020-25686, the attack complexity of a successful attack is reduced. The highest threat from this vulnerability is to data integrity. | ||||
| CVE-2020-25647 | 4 Fedoraproject, Gnu, Netapp and 1 more | 12 Fedora, Grub2, Ontap Select Deploy Administration Utility and 9 more | 2024-11-21 | 7.6 High |
| A flaw was found in grub2 in versions prior to 2.06. During USB device initialization, descriptors are read with very little bounds checking and assumes the USB device is providing sane values. If properly exploited, an attacker could trigger memory corruption leading to arbitrary code execution allowing a bypass of the Secure Boot mechanism. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. | ||||
| CVE-2020-25632 | 4 Fedoraproject, Gnu, Netapp and 1 more | 12 Fedora, Grub2, Ontap Select Deploy Administration Utility and 9 more | 2024-11-21 | 8.2 High |
| A flaw was found in grub2 in versions prior to 2.06. The rmmod implementation allows the unloading of a module used as a dependency without checking if any other dependent module is still loaded leading to a use-after-free scenario. This could allow arbitrary code to be executed or a bypass of Secure Boot protections. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. | ||||
| CVE-2020-25212 | 5 Canonical, Debian, Linux and 2 more | 10 Ubuntu Linux, Debian Linux, Linux Kernel and 7 more | 2024-11-21 | 7.0 High |
| A TOCTOU mismatch in the NFS client code in the Linux kernel before 5.8.3 could be used by local attackers to corrupt memory or possibly have unspecified other impact because a size check is in fs/nfs/nfs4proc.c instead of fs/nfs/nfs4xdr.c, aka CID-b4487b935452. | ||||
| CVE-2020-25211 | 4 Debian, Fedoraproject, Linux and 1 more | 9 Debian Linux, Fedora, Linux Kernel and 6 more | 2024-11-21 | 6.0 Medium |
| In the Linux kernel through 5.8.7, local attackers able to inject conntrack netlink configuration could overflow a local buffer, causing crashes or triggering use of incorrect protocol numbers in ctnetlink_parse_tuple_filter in net/netfilter/nf_conntrack_netlink.c, aka CID-1cc5ef91d2ff. | ||||
| CVE-2020-24513 | 4 Debian, Intel, Redhat and 1 more | 77 Debian Linux, Atom C3308, Atom C3336 and 74 more | 2024-11-21 | 6.5 Medium |
| Domain-bypass transient execution vulnerability in some Intel Atom(R) Processors may allow an authenticated user to potentially enable information disclosure via local access. | ||||
| CVE-2020-24512 | 4 Debian, Intel, Netapp and 1 more | 11 Debian Linux, Microcode, Fas\/aff Bios and 8 more | 2024-11-21 | 3.3 Low |
| Observable timing discrepancy in some Intel(R) Processors may allow an authenticated user to potentially enable information disclosure via local access. | ||||

| Improper isolation of shared resources in some Intel(R) Processors may allow an authenticated user to potentially enable information disclosure via local access. | ||||
| CVE-2020-24489 | 3 Debian, Intel, Redhat | 221 Debian Linux, Atom X5-e3930, Atom X5-e3940 and 218 more | 2024-11-21 | 8.8 High |
| Incomplete cleanup in some Intel(R) VT-d products may allow an authenticated user to potentially enable escalation of privilege via local access. | ||||
| CVE-2020-24394 | 6 Canonical, Linux, Opensuse and 3 more | 11 Ubuntu Linux, Linux Kernel, Leap and 8 more | 2024-11-21 | 7.1 High |
| In the Linux kernel before 5.7.8, fs/nfsd/vfs.c (in the NFS server) can set incorrect permissions on new filesystem objects when the filesystem lacks ACL support, aka CID-22cf8419f131. This occurs because the current umask is not considered. | ||||
| CVE-2020-22219 | 2 Flac Project, Redhat | 6 Flac, Enterprise Linux, Rhel Aus and 3 more | 2024-11-21 | 7.8 High |
| Buffer Overflow vulnerability in function bitwriter_grow_ in flac before 1.4.0 allows remote attackers to run arbitrary code via crafted input to the encoder. | ||||
| CVE-2020-1971 | 9 Debian, Fedoraproject, Netapp and 6 more | 55 Debian Linux, Fedora, Active Iq Unified Manager and 52 more | 2024-11-21 | 5.9 Medium |
| The X.509 GeneralName type is a generic type for representing different types of names. One of those name types is known as EDIPartyName. OpenSSL provides a function GENERAL_NAME_cmp which compares different instances of a GENERAL_NAME to see if they are equal or not. This function behaves incorrectly when both GENERAL_NAMEs contain an EDIPARTYNAME. A NULL pointer dereference and a crash may occur leading to a possible denial of service attack. OpenSSL itself uses the GENERAL_NAME_cmp function for two purposes: 1) Comparing CRL distribution point names between an available CRL and a CRL distribution point embedded in an X509 certificate 2) When verifying that a timestamp response token signer matches the timestamp authority name (exposed via the API functions TS_RESP_verify_response and TS_RESP_verify_token) If an attacker can control both items being compared then that attacker could trigger a crash. For example if the attacker can trick a client or server into checking a malicious certificate against a malicious CRL then this may occur. Note that some applications automatically download CRLs based on a URL embedded in a certificate. This checking happens prior to the signatures on the certificate and CRL being verified. OpenSSL's s_server, s_client and verify tools have support for the "-crl_download" option which implements automatic CRL downloading and this attack has been demonstrated to work against those tools. Note that an unrelated bug means that affected versions of OpenSSL cannot parse or construct correct encodings of EDIPARTYNAME. However it is possible to construct a malformed EDIPARTYNAME that OpenSSL's parser will accept and hence trigger this attack. All OpenSSL 1.1.1 and 1.0.2 versions are affected by this issue. Other OpenSSL releases are out of support and have not been checked. Fixed in OpenSSL 1.1.1i (Affected 1.1.1-1.1.1h). Fixed in OpenSSL 1.0.2x (Affected 1.0.2-1.0.2w). | ||||
| CVE-2020-15862 | 4 Canonical, Net-snmp, Netapp and 1 more | 11 Ubuntu Linux, Net-snmp, Cloud Backup and 8 more | 2024-11-21 | 7.8 High |
| Net-SNMP through 5.8 has Improper Privilege Management because SNMP WRITE access to the EXTEND MIB provides the ability to run arbitrary commands as root. | ||||
