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.

glibc wordexp up to 2.33 may crash or read memory with a crafted pattern due to using atoi instead of strtoul.
