CVE-2023-5156 2 Gnu, Redhat 2 Glibc, Enterprise Linux 2026-10-14 N/A 7.5 HIGH
A flaw was found in the GNU C Library. A recent fix for CVE-2023-4806 introduced the potential for a memory leak, which may result in an application crash.
CVE-2023-4911 7 Canonical, Debian, Fedoraproject and 4 more 49 Ubuntu Linux, Debian Linux, Fedora and 46 more 2026-10-14 N/A 7.8 HIGH
A buffer overflow was discovered in the GNU C Library's dynamic loader ld.so while processing the GLIBC_TUNABLES environment variable. This issue could allow a local attacker to use maliciously crafted GLIBC_TUNABLES environment variables when launching binaries with SUID permission to execute code with elevated privileges.
CVE-2023-4039 1 Gnu 1 Gcc 2026-10-14 N/A 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-2015-1197 1 Gnu 1 Cpio 2026-10-14 1.9 LOW N/A
cpio 2.11, when using the --no-absolute-filenames option, allows local users to write to arbitrary files via a symlink attack on a file in an archive.
CVE-2023-0687 1 Gnu 1 Glibc 2026-10-14 4.0 MEDIUM 4.6 MEDIUM
A vulnerability was found in GNU C Library 2.38. It has been declared as critical. This vulnerability affects the function __monstartup of the file gmon.c of the component Call Graph Monitor. The manipulation leads to buffer overflow. It is recommended to apply a patch to fix this issue. VDB-220246 is the identifier assigned to this vulnerability. NOTE: The real existence of this vulnerability is still doubted at the moment. The inputs that induce this vulnerability are basically addresses of the running application that is built with gmon enabled. It's basically trusted input or input that needs an actual security flaw to be compromised or controlled.
CVE-2023-0361 5 Debian, Fedoraproject, Gnu and 2 more 7 Debian Linux, Fedora, Gnutls and 4 more 2026-10-14 N/A 7.4 HIGH
A timing side-channel in the handling of RSA ClientKeyExchange messages was discovered in GnuTLS. This side-channel can be sufficient to recover the key encrypted in the RSA ciphertext across a network in a Bleichenbacher style attack. To achieve a successful decryption the attacker would need to send a large amount of specially crafted messages to the vulnerable server. By recovering the secret from the ClientKeyExchange message, the attacker would be able to decrypt the application data exchanged over that connection.
CVE-2022-48303 2 Fedoraproject, Gnu 2 Fedora, Tar 2026-10-14 N/A 5.5 MEDIUM
GNU Tar through 1.34 has a one-byte out-of-bounds read that results in use of uninitialized memory for a conditional jump. Exploitation to change the flow of control has not been demonstrated. The issue occurs in from_header in list.c via a V7 archive in which mtime has approximately 11 whitespace characters.
CVE-2022-27943 2 Fedoraproject, Gnu 2 Fedora, Gcc 2026-10-14 4.3 MEDIUM 5.5 MEDIUM
libiberty/rust-demangle.c in GNU GCC 11.2 allows stack consumption in demangle_const, as demonstrated by nm-new.
CVE-2022-23219 3 Debian, Gnu, Oracle 8 Debian Linux, Glibc, Communications Cloud Native Core Binding Support Function and 5 more 2026-10-14 7.5 HIGH 9.8 CRITICAL
The deprecated compatibility function clnt_create in the sunrpc module of the GNU C Library (aka glibc) through 2.34 copies its hostname argument on the stack without validating its length, which may result in a buffer overflow, potentially resulting in a denial of service or (if an application is not built with a stack protector enabled) arbitrary code execution.
CVE-2022-23218 3 Debian, Gnu, Oracle 4 Debian Linux, Glibc, Communications Cloud Native Core Unified Data Repository and 1 more 2026-10-14 7.5 HIGH 9.8 CRITICAL
The deprecated compatibility function svcunix_create in the sunrpc module of the GNU C Library (aka glibc) through 2.34 copies its path argument on the stack without validating its length, which may result in a buffer overflow, potentially resulting in a denial of service or (if an application is not built with a stack protector enabled) arbitrary code execution.
CVE-2022-3715 2 Gnu, Redhat 2 Bash, Enterprise Linux 2026-10-14 N/A 7.8 HIGH
A flaw was found in the bash package, where a heap-buffer overflow can occur in valid parameter_transform. This issue may lead to memory problems.
CVE-2022-2509 4 Debian, Fedoraproject, Gnu and 1 more 4 Debian Linux, Fedora, Gnutls and 1 more 2026-10-14 N/A 7.5 HIGH
A vulnerability found in gnutls. This security flaw happens because of a double free error occurs during verification of pkcs7 signatures in gnutls_pkcs7_verify function.
CVE-2022-1271 4 Debian, Gnu, Redhat and 1 more 4 Debian Linux, Gzip, Jboss Data Grid and 1 more 2026-10-14 N/A 8.8 HIGH
An arbitrary file write vulnerability was found in GNU gzip's zgrep utility. When zgrep is applied on the attacker's chosen file name (for example, a crafted file name), this can overwrite an attacker's content to an arbitrary attacker-selected file. This flaw occurs due to insufficient validation when processing filenames with two or more newlines where selected content and the target file names are embedded in crafted multi-line file names. This flaw allows a remote, low privileged attacker to force zgrep to write arbitrary files on the system.
CVE-2021-46848 3 Debian, Fedoraproject, Gnu 3 Debian Linux, Fedora, Libtasn1 2026-10-14 N/A 9.1 CRITICAL
GNU Libtasn1 before 4.19.0 has an ETYPE_OK off-by-one array size check that affects asn1_encode_simple_der.
CVE-2021-46195 1 Gnu 1 Gcc 2026-10-14 4.3 MEDIUM 5.5 MEDIUM
GCC v12.0 was discovered to contain an uncontrolled recursion via the component libiberty/rust-demangle.c. This vulnerability allows attackers to cause a Denial of Service (DoS) by consuming excessive CPU and memory resources.
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 2026-10-14 5.0 MEDIUM 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-2021-38604 3 Fedoraproject, Gnu, Oracle 8 Fedora, Glibc, Communications Cloud Native Core Binding Support Function and 5 more 2026-10-14 5.0 MEDIUM 7.5 HIGH
In librt in the GNU C Library (aka glibc) through 2.34, sysdeps/unix/sysv/linux/mq_notify.c mishandles certain NOTIFY_REMOVED data, leading to a NULL pointer dereference. NOTE: this vulnerability was introduced as a side effect of the CVE-2021-33574 fix.
CVE-2021-35942 3 Debian, Gnu, Netapp 7 Debian Linux, Glibc, Active Iq Unified Manager and 4 more 2026-10-14 6.4 MEDIUM 9.1 CRITICAL
The wordexp function in the GNU C Library (aka glibc) through 2.33 may crash or read arbitrary memory in parse_param (in posix/wordexp.c) when called with an untrusted, crafted pattern, potentially resulting in a denial of service or disclosure of information. This occurs because atoi was used but strtoul should have been used to ensure correct calculations.
CVE-2021-33574 4 Debian, Fedoraproject, Gnu and 1 more 20 Debian Linux, Fedora, Glibc and 17 more 2026-10-14 7.5 HIGH 9.8 CRITICAL
The mq_notify function in the GNU C Library (aka glibc) versions 2.32 and 2.33 has a use-after-free. It may use the notification thread attributes object (passed through its struct sigevent parameter) after it has been freed by the caller, leading to a denial of service (application crash) or possibly unspecified other impact.
CVE-2021-27645 3 Debian, Fedoraproject, Gnu 3 Debian Linux, Fedora, Glibc 2026-10-14 1.9 LOW 2.5 LOW
The nameserver caching daemon (nscd) in the GNU C Library (aka glibc or libc6) 2.29 through 2.33, when processing a request for netgroup lookup, may crash due to a double-free, potentially resulting in degraded service or Denial of Service on the local system. This is related to netgroupcache.c.
