## Description

A flaw was found in libXpm. When processing files with .Z or .gz
extensions, the library calls external programs to compress and uncompress
files, relying on the PATH environment variable to find these programs,
which could allow a malicious user to execute other programs by
manipulating the PATH environment variable.
