The iconv function in the GNU C Library (aka glibc or libc6) 2.32 and earlier, when processing invalid input sequences in the ISO-2022-JP-3 encoding, fails an assertion in the code path and aborts the program, potentially resulting in a denial of service.
CVE-2020-29562 3 Fedoraproject, Gnu, Netapp 3 Fedora, Glibc, E-series Santricity Os Controller 2025-06-09 2.1 LOW 4.8 MEDIUM
The iconv function in the GNU C Library (aka glibc or libc6) 2.30 to 2.32, when converting UCS4 text containing an irreversible character, fails an assertion in the code path and aborts the program, potentially resulting in a denial of service.
CVE-2020-27618 4 Debian, Gnu, Netapp and 1 more 24 Debian Linux, Glibc, 500f and 21 more 2025-06-09 2.1 LOW 5.5 MEDIUM
The iconv function in the GNU C Library (aka glibc or libc6) 2.32 and earlier, when processing invalid multi-byte input sequences in IBM1364, IBM1371, IBM1388, IBM1390, and IBM1399 encodings, fails to advance the input state, which could lead to an infinite loop in applications, resulting in a denial of service, a different vulnerability from CVE-2016-10228.
CVE-2019-25013 5 Broadcom, Debian, Fedoraproject and 2 more 10 Fabric Operating System, Debian Linux, Fedora and 7 more 2025-06-09 7.1 HIGH 5.9 MEDIUM
The iconv feature in the GNU C Library (aka glibc or libc6) through 2.32, when processing invalid multi-byte input sequences in the EUC-KR encoding, may have a buffer over-read.
CVE-2021-3998 2 Gnu, Netapp 12 Glibc, H300s, H300s Firmware and 9 more 2025-06-09 N/A 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-2021-27645 3 Debian, Fedoraproject, Gnu 3 Debian Linux, Fedora, Glibc 2025-06-09 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.
CVE-2021-38604 3 Fedoraproject, Gnu, Oracle 8 Fedora, Glibc, Communications Cloud Native Core Binding Support Function and 5 more 2025-05-30 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-2023-4911 6 Canonical, Debian, Fedoraproject and 3 more 38 Ubuntu Linux, Debian Linux, Fedora and 35 more 2025-05-06 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-2022-23219 3 Debian, Gnu, Oracle 8 Debian Linux, Glibc, Communications Cloud Native Core Binding Support Function and 5 more 2025-05-05 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 2025-05-05 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-2021-35942 3 Debian, Gnu, Netapp 7 Debian Linux, Glibc, Active Iq Unified Manager and 4 more 2025-05-01 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-2023-4813 4 Fedoraproject, Gnu, Netapp and 1 more 21 Fedora, Glibc, Active Iq Unified Manager and 18 more 2025-04-30 N/A 5.9 MEDIUM
A flaw was found in glibc. In an uncommon situation, the gaih_inet function may use memory that has been freed, resulting in an application crash. This issue is only exploitable when the getaddrinfo function is called and the hosts database in /etc/nsswitch.conf is configured with SUCCESS=continue or SUCCESS=merge.
CVE-2023-4806 3 Fedoraproject, Gnu, Redhat 22 Fedora, Glibc, Codeready Linux Builder Eus and 19 more 2025-04-30 N/A 5.9 MEDIUM
A flaw was found in glibc. In an extremely rare situation, the getaddrinfo function may access memory that has been freed, resulting in an application crash. This issue is only exploitable when a NSS module implements only the _nss_*_gethostbyname2_r and _nss_*_getcanonname_r hooks without implementing the _nss_*_gethostbyname3_r hook. The resolved name should return a large number of IPv6 and IPv4, and the call to the getaddrinfo function should have the AF_INET6 address family with AI_CANONNAME, AI_ALL and AI_V4MAPPED as flags.
CVE-2015-5180 2 Canonical, Gnu 2 Ubuntu Linux, Glibc 2025-04-20 5.0 MEDIUM 7.5 HIGH
res_query in libresolv in glibc before 2.25 allows remote attackers to cause a denial of service (NULL pointer dereference and process crash).
CVE-2015-8983 1 Gnu 1 Glibc 2025-04-20 6.8 MEDIUM 8.1 HIGH
Integer overflow in the _IO_wstr_overflow function in libio/wstrops.c in the GNU C Library (aka glibc or libc6) before 2.22 allows context-dependent attackers to cause a denial of service (application crash) or possibly execute arbitrary code via vectors related to computing a size in bytes, which triggers a heap-based buffer overflow.
CVE-2017-15671 1 Gnu 1 Glibc 2025-04-20 4.3 MEDIUM 5.9 MEDIUM
The glob function in glob.c in the GNU C Library (aka glibc or libc6) before 2.27, when invoked with GLOB_TILDE, could skip freeing allocated memory when processing the ~ operator with a long user name, potentially leading to a denial of service (memory leak).
CVE-2014-9984 1 Gnu 1 Glibc 2025-04-20 7.5 HIGH 9.8 CRITICAL
nscd in the GNU C Library (aka glibc or libc6) before version 2.20 does not correctly compute the size of an internal buffer when processing netgroup requests, possibly leading to an nscd daemon crash or code execution as the user running nscd.
CVE-2016-5417 1 Gnu 1 Glibc 2025-04-20 5.0 MEDIUM 7.5 HIGH
Memory leak in the __res_vinit function in the IPv6 name server management code in libresolv in GNU C Library (aka glibc or libc6) before 2.24 allows remote attackers to cause a denial of service (memory consumption) by leveraging partial initialization of internal resolver data structures.
CVE-2015-8985 1 Gnu 1 Glibc 2025-04-20 4.3 MEDIUM 5.9 MEDIUM
The pop_fail_stack function in the GNU C Library (aka glibc or libc6) allows context-dependent attackers to cause a denial of service (assertion failure and application crash) via vectors related to extended regular expression processing.
CVE-2015-8984 1 Gnu 1 Glibc 2025-04-20 4.3 MEDIUM 5.9 MEDIUM
The fnmatch function in the GNU C Library (aka glibc or libc6) before 2.22 might allow context-dependent attackers to cause a denial of service (application crash) via a malformed pattern, which triggers an out-of-bounds read.
