GLSA-200506-16 : cpio: Directory traversal vulnerability
Low Nessus Plugin ID 18531
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe remote host is affected by the vulnerability described in GLSA-200506-16 (cpio: Directory traversal vulnerability)
A vulnerability has been found in cpio that can potentially allow a cpio archive to extract its files to an arbitrary directory of the creator's choice.
An attacker could create a malicious cpio archive which would create files in arbitrary locations on the victim's system. This issue could also be used in conjunction with a previous race condition vulnerability (CAN-2005-1111) to change permissions on files owned by the victim.
There is no known workaround at this time.
SolutionAll cpio users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=app-arch/cpio-2.6-r3'
