Description Guilherme de Almeida Suckevicz 2023-01-11 19:25:18 UTC 
By default, on all platforms except MinGW, libXpm will detect if a filename ends in .Z or .gz, and will when reading such a file fork off an uncompress or gunzip command to read from via a pipe, and when writing such a file will fork off a compress or gzip command to write to via a pipe.

In libXpm 3.5.14 or older these are run via execlp(), relying on $PATH to find the commands.  If libXpm is called from a program running with raised privileges, such as via setuid, then a malicious user could set $PATH to include programs of their choosing to be run with those privileges.
