6.8
CVSSv2
CVE-2017-17426
The malloc function in the GNU C Library (aka glibc or libc6) 2.26 could return a memory block that is too small if an attempt is made to allocate an object whose size is close to SIZE_MAX, potentially leading to a subsequent heap overflow. This occurs because the per-thread cach...

CVE-2012-3480
Multiple integer overflows in the (1) strtod, (2) strtof, (3) strtold, (4) strtod_l, and other unspecified "related functions" in stdlib in GNU C Library (aka glibc or libc6) 2.16 allow local users to cause a denial of service (application crash) and possibly execute ar...

CVE-2023-25139
sprintf in the GNU C Library (glibc) 2.37 has a buffer overflow (out-of-bounds write) in some situations with a correct buffer size. This is unrelated to CWE-676. It may write beyond the bounds of the destination buffer when attempting to write a padded, thousands-separated strin...

CVSSv2
CVE-2000-0959
glibc2 does not properly clear the LD_DEBUG_OUTPUT and LD_DEBUG environmental variables when a program is spawned from a setuid program, which could allow local users to overwrite files via a symlink attack.
Gnu Glibc 2.1.3.10

CVSSv2
CVE-2012-0864
Integer overflow in the vfprintf function in stdio-common/vfprintf.c in glibc 2.14 and other versions allows context-dependent malicious users to bypass the FORTIFY_SOURCE protection mechanism, conduct format string attacks, and write to arbitrary memory via a large number of arg...

CVSSv2
CVE-2014-4043
The posix_spawn_file_actions_addopen function in glibc prior to 2.20 does not copy its path argument in accordance with the POSIX specification, which allows context-dependent malicious users to trigger use-after-free vulnerabilities.

CVE-2016-10739
In the GNU C Library (aka glibc or libc6) up to and including 2.28, the getaddrinfo function would successfully parse a string that contained an IPv4 address followed by whitespace and arbitrary characters, which could lead applications to incorrectly assume that it had parsed a ...

CVE-2002-0684
Buffer overflow in DNS resolver functions that perform lookup of network names and addresses, as used in BIND 4.9.8 and ported to glibc 2.2.5 and previous versions, allows remote malicious DNS servers to execute arbitrary code through a subroutine used by functions such as getnet...

CVE-2016-3706
Stack-based buffer overflow in the getaddrinfo function in sysdeps/posix/getaddrinfo.c in the GNU C Library (aka glibc or libc6) allows remote malicious users to cause a denial of service (crash) via vectors involving hostent conversion. NOTE: this vulnerability exists because of...

CVE-2023-6779
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 incor...
