GLSA-200603-06 : GNU tar: Buffer overflow
Medium Nessus Plugin ID 21044
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe remote host is affected by the vulnerability described in GLSA-200603-06 (GNU tar: Buffer overflow)
Jim Meyering discovered a flaw in the handling of certain header fields that could result in a buffer overflow when extracting or listing the contents of an archive.
A remote attacker could construct a malicious tar archive that could potentially execute arbitrary code with the privileges of the user running GNU tar.
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-1.15.1-r1'
