CVE-2021-35942
Last modified
CVE-2021-35942 is a critical-severity vulnerability rated 9.1/10 on the CVSS scale. 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.. EPSS estimates a 2.68% chance of exploitation in the next 30 days.
