https://notcve.org/view.php?id=CVE-2021-3999
02 Mar 2022 — 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... • https://access.redhat.com/security/cve/CVE-2021-3999 • CWE-193: Off-by-one Error •

CVE-2021-35942 – glibc: Arbitrary read in wordexp()
https://notcve.org/view.php?id=CVE-2021-35942
22 Jul 2021 — 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-2020-29573 – glibc: stack-based buffer overflow if the input to any of the printf family of functions is an 80-bit long double with a non-canonical bit pattern
https://notcve.org/view.php?id=CVE-2020-29573
05 Dec 2020 — sysdeps/i386/ldbl2mpn.c in the GNU C Library (aka glibc or libc6) before 2.23 on x86 targets has a stack-based buffer overflow if the input to any of the printf family of functions is an 80-bit long double with a non-canonical bit pattern, as seen when passing a \x00\x04\x00\x00\x00\x00\x00\x00\x00\x04 value to sprintf. NOTE: the issue does not affect glibc by default in 2016 or later (i.e., 2.23 or later) because of commits made in 2015 for inlining of C99 math functions through use of GCC built-ins.

CVE-2020-1752 – glibc: use-after-free in glob() function when expanding ~user
https://notcve.org/view.php?id=CVE-2020-1752
30 Apr 2020 — A use-after-free vulnerability introduced in glibc upstream version 2.14 was found in the way the tilde expansion was carried out. Directory paths containing an initial tilde followed by a valid username were affected by this issue. A local attacker could exploit this flaw by creating a specially crafted path that, when processed by the glob function, would potentially lead to arbitrary code execution. This was fixed in version 2.32. Una vulnerabilidad de uso de la memoria previamente liberada introducida e... • https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2020-1752 • CWE-416: Use After Free •
