Description

gpgtar in GnuPG before 2.5.19 can allow file overwrite via crafted data in an archive. When extracting an untrusted archive with --directory (aka -C) into an existing directory containing a pre-existing symlink, gpgtar can follow that symlink and create or overwrite a file outside the selected extraction directory. The write is limited by the extraction user's filesystem permissions. An archive extracted into a fresh empty directory does not have this risk.

Affected products

• GnuPG: before 2.5.19 — fixed in 2.5.19

How to fix

Upgrade to a fixed version: GnuPG 2.5.19. Check the vendor advisory for mitigations.
