end_pattern (called from internal_fnmatch) 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), as demonstrated by use of the fnmatch library function with the **(!() pattern. NOTE: this is not the same as CVE-2015-8984; also, some Linux distributions have fixed CVE-2015-8984 but have not fixed this additional fnmatch issue. • https://security.netapp.com/advisory/ntap-20230731-0009 https://sourceware.org/bugzilla/show_bug.cgi?id=18036 • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') •

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. Se ha encontrado un fallo en glibc. La función realpath() puede devolver por error un valor no esperado, conllevando potencialmente a un filtrado de información y una divulgación de datos confidenciales. • https://access.redhat.com/security/cve/CVE-2021-3998 https://bugzilla.redhat.com/show_bug.cgi?id=2024633 https://security-tracker.debian.org/tracker/CVE-2021-3998 https://security.netapp.com/advisory/ntap-20221020-0003 https://sourceware.org/bugzilla/show_bug.cgi?id=28770 https://sourceware.org/git/gitweb.cgi?p=glibc.git%3Bh=84d2d0fe20bdf94feed82b21b4d7d136db471f03 https://sourceware.org/git/gitweb.cgi?p=glibc.git%3Bh=ee8d5e33adb284601c00c94687bc907e10aec9bb https://www.openwall.com/lists/oss-security/2022 • CWE-125: Out-of-bounds Read CWE-252: Unchecked Return Value •

https://notcve.org/view.php?id=CVE-2021-3999
A flaw was found in glibc. An off-by-one buffer overflow and underflow in getcwd() may lead to memory corruption when the size of the buffer is exactly 1. A local attacker who can control the input buffer and size passed to getcwd() in a setuid program could use this flaw to potentially execute arbitrary code and escalate their privileges on the system. Se ha encontrado un fallo en glibc. Un desbordamiento y subdesbordamiento de búfer en la función getcwd() puede conllevar a una corrupción de memoria cuando el tamaño del búfer es exactamente 1. • https://access.redhat.com/security/cve/CVE-2021-3999 https://bugzilla.redhat.com/show_bug.cgi?id=2024637 https://lists.debian.org/debian-lts-announce/2022/10/msg00021.html https://security-tracker.debian.org/tracker/CVE-2021-3999 https://security.netapp.com/advisory/ntap-20221104-0001 https://sourceware.org/bugzilla/show_bug.cgi?id=28769 https://sourceware.org/git/gitweb.cgi?p=glibc.git%3Bh=23e0e8f5f1fb5ed150253d986ecccdc90c2dcd5e https://www.openwall.com/lists/oss-security/2022/01/24/4 • CWE-193: Off-by-one Error •

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.
