NVD Description

Note: Versions mentioned in the description apply only to the upstream libpar-packer-perl package and not the libpar-packer-perl package as distributed by Debian. See How to fix? for Debian:8 relevant fixed versions and status.

The par_mktmpdir function in the PAR::Packer module before 1.012 for Perl creates temporary files in a directory with a predictable name without verifying ownership and permissions of this directory, which allows local users to overwrite files when another user extracts a PAR packed program. NOTE: a similar vulnerability was reported for PAR, but this has been assigned a different CVE identifier.
