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

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

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-2015-5180)

A buffer overflow has been discovered in the GNU C Library (aka glibc or libc6) in the __mempcpy_avx512_no_vzeroupper function when particular conditions are met. An attacker could use this vulnerability to cause a denial of service or potentially execute code.(CVE-2018-11237)

In the GNU C Library (aka glibc or libc6) through 2.29, proceed_next_node in posix/regexec.c has a heap-based buffer over-read via an attempted case-insensitive regular-expression match.(CVE-2019-9169)

The iconv program in the GNU C Library (aka glibc or libc6) 2.25 and earlier, when invoked with the -c option, enters an infinite loop when processing invalid multi-byte input sequences, leading to a denial of service.(CVE-2016-10228)

The DNS stub resolver in the GNU C Library (aka glibc or libc6) before version 2.26, when EDNS support is enabled, will solicit large UDP responses from name servers, potentially simplifying off-path DNS spoofing attacks due to IP fragmentation.(CVE-2017-12132)");
