Description Vladimir Vasilev 2026-10-07 18:24:10 UTC

Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

patool before 4.0.6 contains an OS command injection vulnerability on Windows because shell_quote_nt fails to escape cmd.exe metacharacters or embedded double quotes in archive filenames. Attackers can supply crafted filenames like report&calc.gz for single-file formats run with shell=True to execute commands with patool process privileges.

Hmmmm... "on Windows" ? :-)

Good point :) I'm closing this. Apologies.
