Description

The remote host is affected by the vulnerability described in GLSA-201111-11 (GNU Tar: User-assisted execution of arbitrary code)

GNU Tar is vulnerable to a boundary error in the rmt_read__ function in lib/rtapelib.c, which could cause a heap-based buffer overflow.
Impact :

A remote attacker could entice the user to load a specially crafted archive, possibly resulting in the execution of arbitrary code or a Denial of Service.
Workaround :

Solution

All GNU Tar users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=app-arch/tar-1.23' NOTE: This is a legacy GLSA. Updates for all affected architectures are available since July 18, 2010. It is likely that your system is already no longer affected by this issue.
