GLSA-201111-11 : GNU Tar: User-assisted execution of arbitrary code
Medium Nessus Plugin ID 56907
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe 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.
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.
There is no known workaround at this time.
SolutionAll 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.
