CVE-2021-43412 1 Gnu 1 Hurd 2024-11-21 7.8 High
An issue was discovered in GNU Hurd before 0.9 20210404-9. libports accepts fake notification messages from any client on any port, which can lead to port use-after-free. This can be exploited for local privilege escalation to get full root access.
CVE-2021-43411 1 Gnu 1 Hurd 2024-11-21 7.5 High
An issue was discovered in GNU Hurd before 0.9 20210404-9. When trying to exec a setuid executable, there's a window of time when the process already has the new privileges, but still refers to the old task and is accessible through the old process port. This can be exploited to get full root access.
CVE-2021-43396 2 Gnu, Oracle 7 Glibc, Communications Cloud Native Core Binding Support Function, Communications Cloud Native Core Network Function Cloud Native Environment and 4 more 2024-11-21 7.5 High
In iconvdata/iso-2022-jp-3.c in the GNU C Library (aka glibc) 2.34, remote attackers can force iconv() to emit a spurious '\0' character via crafted ISO-2022-JP-3 data that is accompanied by an internal state reset. This may affect data integrity in certain iconv() use cases. NOTE: the vendor states "the bug cannot be invoked through user input and requires iconv to be invoked with a NULL inbuf, which ought to require a separate application bug to do so unintentionally. Hence there's no security impact to the bug.
CVE-2021-43332 2 Debian, Gnu 2 Debian Linux, Mailman 2024-11-21 6.5 Medium
In GNU Mailman before 2.1.36, the CSRF token for the Cgi/admindb.py admindb page contains an encrypted version of the list admin password. This could potentially be cracked by a moderator via an offline brute-force attack.
CVE-2021-43331 2 Debian, Gnu 2 Debian Linux, Mailman 2024-11-21 6.1 Medium
In GNU Mailman before 2.1.36, a crafted URL to the Cgi/options.py user options page can execute arbitrary JavaScript for XSS.
CVE-2021-42586 1 Gnu 1 Libredwg 2024-11-21 8.8 High
A heap buffer overflow was discovered in copy_bytes in decode_r2007.c in dwgread before 0.12.4 via a crafted dwg file.
CVE-2021-42585 1 Gnu 1 Libredwg 2024-11-21 8.8 High
A heap buffer overflow was discovered in copy_compressed_bytes in decode_r2007.c in dwgread before 0.12.4 via a crafted dwg file.
CVE-2021-42097 3 Debian, Gnu, Redhat 4 Debian Linux, Mailman, Enterprise Linux and 1 more 2024-11-21 8.0 High
GNU Mailman before 2.1.35 may allow remote Privilege Escalation. A csrf_token value is not specific to a single user account. An attacker can obtain a value within the context of an unprivileged user account, and then use that value in a CSRF attack against an admin (e.g., for account takeover).
CVE-2021-42096 3 Debian, Gnu, Redhat 4 Debian Linux, Mailman, Enterprise Linux and 1 more 2024-11-21 4.3 Medium
GNU Mailman before 2.1.35 may allow remote Privilege Escalation. A certain csrf_token value is derived from the admin password, and may be useful in conducting a brute-force attack against that password.
CVE-2021-40491 2 Debian, Gnu 2 Debian Linux, Inetutils 2024-11-21 6.5 Medium
The ftp client in GNU Inetutils before 2.2 does not validate addresses returned by PASV/LSPV responses to make sure they match the server address. This is similar to CVE-2020-8284 for curl.
CVE-2021-3999 4 Debian, Gnu, Netapp and 1 more 16 Debian Linux, Glibc, E-series Performance Analyzer and 13 more 2024-11-21 7.8 High
A flaw was found in glibc. An off-by-one buffer overflow and underflow in getcwd() may lead to memory corruption when the size of the buffer is exactly 1. A local attacker who can control the input buffer and size passed to getcwd() in a setuid program could use this flaw to potentially execute arbitrary code and escalate their privileges on the system.
CVE-2021-3998 2 Gnu, Netapp 12 Glibc, H300s, H300s Firmware and 9 more 2024-11-21 7.5 High
A flaw was found in glibc. The realpath() function can mistakenly return an unexpected value, potentially leading to information leakage and disclosure of sensitive data.
CVE-2021-3826 3 Fedoraproject, Gnu, Redhat 4 Fedora, Gcc, Enterprise Linux and 1 more 2024-11-21 6.5 Medium
Heap/stack buffer overflow in the dlang_lname function in d-demangle.c in libiberty allows attackers to potentially cause a denial of service (segmentation fault and crash) via a crafted mangled symbol.
CVE-2021-3697 2 Gnu, Redhat 14 Grub2, Codeready Linux Builder, Developer Tools and 11 more 2024-11-21 7.0 High
A crafted JPEG image may lead the JPEG reader to underflow its data pointer, allowing user-controlled data to be written in heap. To a successful to be performed the attacker needs to perform some triage over the heap layout and craft an image with a malicious format and payload. This vulnerability can lead to data corruption and eventual code execution or secure boot circumvention. This flaw affects grub2 versions prior grub-2.12.
CVE-2021-3696 3 Gnu, Netapp, Redhat 15 Grub2, Ontap Select Deploy Administration Utility, Codeready Linux Builder and 12 more 2024-11-21 4.5 Medium
A heap out-of-bounds write may heppen during the handling of Huffman tables in the PNG reader. This may lead to data corruption in the heap space. Confidentiality, Integrity and Availablity impact may be considered Low as it's very complex to an attacker control the encoding and positioning of corrupted Huffman entries to achieve results such as arbitrary code execution and/or secure boot circumvention. This flaw affects grub2 versions prior grub-2.12.
CVE-2021-3695 4 Fedoraproject, Gnu, Netapp and 1 more 16 Fedora, Grub2, Ontap Select Deploy Administration Utility and 13 more 2024-11-21 4.5 Medium
A crafted 16-bit grayscale PNG image may lead to a out-of-bounds write in the heap area. An attacker may take advantage of that to cause heap data corruption or eventually arbitrary code execution and circumvent secure boot protections. This issue has a high complexity to be exploited as an attacker needs to perform some triage over the heap layout to achieve signifcant results, also the values written into the memory are repeated three times in a row making difficult to produce valid payloads. This flaw affects grub2 versions prior grub-2.12.
CVE-2021-3549 1 Gnu 1 Binutils 2024-11-21 7.1 High
An out of bounds flaw was found in GNU binutils objdump utility version 2.36. An attacker could use this flaw and pass a large section to avr_elf32_load_records_from_section() probably resulting in a crash or in some cases memory corruption. The highest threat from this vulnerability is to integrity as well as system availability.
CVE-2021-3530 2 Gnu, Netapp 2 Binutils, Ontap Select Deploy Administration Utility 2024-11-21 7.5 High
A flaw was discovered in GNU libiberty within demangle_path() in rust-demangle.c, as distributed in GNU Binutils version 2.36. A crafted symbol can cause stack memory to be exhausted leading to a crash.
CVE-2021-3466 3 Fedoraproject, Gnu, Redhat 3 Fedora, Libmicrohttpd, Enterprise Linux 2024-11-21 9.8 Critical
A flaw was found in libmicrohttpd. A missing bounds check in the post_process_urlencoded function leads to a buffer overflow, allowing a remote attacker to write arbitrary data in an application that uses libmicrohttpd. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. Only version 0.9.70 is vulnerable.
CVE-2021-3418 1 Gnu 1 Grub2 2024-11-21 6.4 Medium
If certificates that signed grub are installed into db, grub can be booted directly. It will then boot any kernel without signature validation. The booted kernel will think it was booted in secureboot mode and will implement lockdown, yet it could have been tampered. This flaw is a reintroduction of CVE-2020-15705 and only affects grub2 versions prior to 2.06 and upstream and distributions using the shim_lock mechanism.
