CVE-2015-8982
Integer overflow in the strxfrm function in the GNU C Library (aka glibc or libc6) prior to 2.21 allows context-dependent malicious users to cause a denial of service (crash) or possibly execute arbitrary code via a long string, which triggers a stack-based buffer overflow.

CVSSv2
CVE-2015-8985
The pop_fail_stack function in the GNU C Library (aka glibc or libc6) allows context-dependent malicious users to cause a denial of service (assertion failure and application crash) via vectors related to extended regular expression processing.

CVSSv2
CVE-2002-1146
The BIND 4 and BIND 8.2.x stub resolver libraries, and other libraries such as glibc 2.2.5 and previous versions, libc, and libresolv, use the maximum buffer size instead of the actual size when processing a DNS response, which causes the stub resolvers to read past the actual bo...

CVE-2018-6551
The malloc implementation in the GNU C Library (aka glibc or libc6), from version 2.24 to 2.26 on powerpc, and only in version 2.26 on i386, did not properly handle malloc calls with arguments close to SIZE_MAX and could return a pointer to a heap region that is smaller than requ...

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-2017-8804
The xdr_bytes and xdr_string functions in the GNU C Library (aka glibc or libc6) 2.25 mishandle failures of buffer deserialization, which allows remote malicious users to cause a denial of service (virtual memory allocation, or memory consumption if an overcommit setting is not u...

CVE-2013-0242
Buffer overflow in the extend_buffers function in the regular expression matcher (posix/regexec.c) in glibc, possibly 2.17 and previous versions, allows context-dependent malicious users to cause a denial of service (memory corruption and crash) via crafted multibyte characters.

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-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...
