The exploit has been disclosed to the public and may be used. The patch is named f9978defb6fab0bd8583942d97c112b0932ac814. It is recommended to apply a patch to fix this issue. | ||||
| CVE-2024-33602 | 2 Gnu, Redhat | 8 Glibc, Enterprise Linux, Rhel Aus and 5 more | 2025-02-13 | 7.4 High |
| nscd: netgroup cache assumes NSS callback uses in-buffer strings The Name Service Cache Daemon's (nscd) netgroup cache can corrupt memory when the NSS callback does not store all strings in the provided buffer. The flaw was introduced in glibc 2.15 when the cache was added to nscd. This vulnerability is only present in the nscd binary. | ||||
| CVE-2024-2961 | 2 Gnu, Redhat | 9 Glibc, Enterprise Linux, Openshift and 6 more | 2025-02-13 | 7.3 High |
| The iconv() function in the GNU C Library versions 2.39 and older may overflow the output buffer passed to it by up to 4 bytes when converting strings to the ISO-2022-CN-EXT character set, which may be used to crash an application or overwrite a neighbouring variable. | ||||
| CVE-2023-6779 | 3 Fedoraproject, Gnu, Redhat | 3 Fedora, Glibc, Enterprise Linux | 2025-02-13 | 8.2 High |
| An off-by-one heap-based buffer overflow was found in the __vsyslog_internal function of the glibc library. This function is called by the syslog and vsyslog functions. This issue occurs when these functions are called with a message bigger than INT_MAX bytes, leading to an incorrect calculation of the buffer size to store the message, resulting in an application crash. This issue affects glibc 2.37 and newer. | ||||
| CVE-2023-6246 | 3 Fedoraproject, Gnu, Redhat | 3 Fedora, Glibc, Enterprise Linux | 2025-02-13 | 8.4 High |
| A heap-based buffer overflow was found in the __vsyslog_internal function of the glibc library. This function is called by the syslog and vsyslog functions. This issue occurs when the openlog function was not called, or called with the ident argument set to NULL, and the program name (the basename of argv[0]) is bigger than 1024 bytes, resulting in an application crash or local privilege escalation. This issue affects glibc 2.36 and newer. | ||||
| CVE-2023-4039 | 1 Gnu | 1 Gcc | 2025-02-13 | 4.8 Medium |
| **DISPUTED**A failure in the -fstack-protector feature in GCC-based toolchains that target AArch64 allows an attacker to exploit an existing buffer overflow in dynamically-sized local variables in your application without this being detected. This stack-protector failure only applies to C99-style dynamically-sized local variables or those created using alloca(). The stack-protector operates as intended for statically-sized local variables. The default behavior when the stack-protector detects an overflow is to terminate your application, resulting in controlled loss of availability. An attacker who can exploit a buffer overflow without triggering the stack-protector might be able to change program flow control to cause an uncontrolled loss of availability or to go further and affect confidentiality or integrity. NOTE: The GCC project argues that this is a missed hardening bug and not a vulnerability by itself. | ||||
| CVE-2023-25588 | 2 Gnu, Redhat | 2 Binutils, Enterprise Linux | 2025-02-13 | 4.7 Medium |
| A flaw was found in Binutils. The field `the_bfd` of `asymbol`struct is uninitialized in the `bfd_mach_o_get_synthetic_symtab` function, which may lead to an application crash and local denial of service. | ||||
| CVE-2023-25586 | 2 Gnu, Redhat | 2 Binutils, Enterprise Linux | 2025-02-13 | 4.7 Medium |
| A flaw was found in Binutils. A logic fail in the bfd_init_section_decompress_status function may lead to the use of an uninitialized variable that can cause a crash and local denial of service. | ||||
| CVE-2023-25585 | 2 Gnu, Redhat | 2 Binutils, Enterprise Linux | 2025-02-13 | 4.7 Medium |
| A flaw was found in Binutils. The use of an uninitialized field in the struct module *module may lead to application crash and local denial of service. | ||||
| CVE-2023-25584 | 2 Gnu, Redhat | 2 Binutils, Enterprise Linux | 2025-02-13 | 6.3 Medium |
| An out-of-bounds read flaw was found in the parse_module function in bfd/vms-alpha.c in Binutils. | ||||
| CVE-2022-28736 | 2 Gnu, Redhat | 4 Grub2, Enterprise Linux, Rhel E4s and 1 more | 2025-02-13 | 6.4 Medium |
| There's a use-after-free vulnerability in grub_cmd_chainloader() function; The chainloader command is used to boot up operating systems that doesn't support multiboot and do not have direct support from GRUB2. When executing chainloader more than once a use-after-free vulnerability is triggered. If an attacker can control the GRUB2's memory allocation pattern sensitive data may be exposed and arbitrary code execution can be achieved. | ||||
| CVE-2022-28735 | 2 Gnu, Redhat | 4 Grub2, Enterprise Linux, Rhel E4s and 1 more | 2025-02-13 | 6.7 Medium |
| The GRUB2's shim_lock verifier allows non-kernel files to be loaded on shim-powered secure boot systems. Allowing such files to be loaded may lead to unverified code and modules to be loaded in GRUB2 breaking the secure boot trust-chain. | ||||
| CVE-2022-28734 | 3 Gnu, Netapp, Redhat | 5 Grub2, Active Iq Unified Manager, Enterprise Linux and 2 more | 2025-02-13 | 8.1 High |
| Out-of-bounds write when handling split HTTP headers; When handling split HTTP headers, GRUB2 HTTP code accidentally moves its internal data buffer point by one position. This can lead to a out-of-bound write further when parsing the HTTP request, writing a NULL byte past the buffer. It's conceivable that an attacker controlled set of packets can lead to corruption of the GRUB2's internal memory metadata. | ||||
| CVE-2022-28733 | 2 Gnu, Redhat | 5 Grub2, Enterprise Linux, Rhel E4s and 2 more | 2025-02-13 | 8.1 High |
| Integer underflow in grub_net_recv_ip4_packets; A malicious crafted IP packet can lead to an integer underflow in grub_net_recv_ip4_packets() function on rsm->total_len value. Under certain circumstances the total_len value may end up wrapping around to a small integer number which will be used in memory allocation. If the attack succeeds in such way, subsequent operations can write past the end of the buffer. | ||||
| CVE-2021-3981 | 3 Fedoraproject, Gnu, Redhat | 3 Fedora, Grub2, Enterprise Linux | 2025-02-13 | 3.3 Low |
| A flaw in grub2 was found where its configuration file, known as grub.cfg, is being created with the wrong permission set allowing non privileged users to read its content. This represents a low severity confidentiality issue, as those users can eventually read any encrypted passwords present in grub.cfg. This flaw affects grub2 2.06 and previous versions. This issue has been fixed in grub upstream but no version with the fix is currently released. | ||||
| CVE-2019-14866 | 2 Gnu, Redhat | 4 Cpio, Enterprise Linux, Openshift Do and 1 more | 2025-02-13 | 7.3 High |
| In all versions of cpio before 2.13 does not properly validate input files when generating TAR archives. When cpio is used to create TAR archives from paths an attacker can write to, the resulting archive may contain files with permissions the attacker did not have or in paths he did not have access to. Extracting those archives from a high-privilege user without carefully reviewing them may lead to the compromise of the system. | ||||
| CVE-2019-14865 | 2 Gnu, Redhat | 3 Grub2, Enterprise Linux, Enterprise Linux Eus | 2025-02-13 | 5.5 Medium |
| A flaw was found in the grub2-set-bootflag utility of grub2. A local attacker could run this utility under resource pressure (for example by setting RLIMIT), causing grub2 configuration files to be truncated and leaving the system unbootable on subsequent reboots. | ||||
| CVE-2013-4577 | 1 Gnu | 1 Grub | 2025-02-13 | N/A |
| A certain Debian patch for GNU GRUB uses world-readable permissions for grub.cfg, which allows local users to obtain password hashes, as demonstrated by reading the password_pbkdf2 directive in the file. | ||||
| CVE-2010-3856 | 2 Gnu, Redhat | 2 Glibc, Enterprise Linux | 2025-02-13 | N/A |
| ld.so in the GNU C Library (aka glibc or libc6) before 2.11.3, and 2.12.x before 2.12.2, does not properly restrict use of the LD_AUDIT environment variable to reference dynamic shared objects (DSOs) as audit objects, which allows local users to gain privileges by leveraging an unsafe DSO located in a trusted library directory, as demonstrated by libpcprofile.so. | ||||
