Red Hat has issued security advisories and updates addressing this vulnerability. Updated packages for perl-Archive-Tar are available for Red Hat Enterprise Linux 10 and related variants. Users should apply these official patches to remediate the issue. Refer to Red Hat advisory RHSA-2026:30857 and the linked article https://access.redhat.com/articles/11258 for update instructions. Patch status is confirmed by the vendor advisories. No alternative mitigations are specified.

Description

Archive::Tar versions before 3.08 for Perl extract symlinks with attacker controlled targets outside the extraction directory. _make_special_file() passes the tar header's linkname to symlink() without validating it against absolute paths or .. segments. The secure-extract mode check that guards regular file extraction does not cover the symlink target. A subsequent open through the extracted name reads or writes the attacker chosen path.
