NVD Description

Note: Versions mentioned in the description apply only to the upstream glibc-langpack-sid package and not the glibc-langpack-sid package as distributed by Oracle. See How to fix? for Oracle:8 relevant fixed versions and status.

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.
