GLSA-200711-18 : Cpio: Buffer overflow
High Nessus Plugin ID 28218
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe remote host is affected by the vulnerability described in GLSA-200711-18 (Cpio: Buffer overflow)
A buffer overflow vulnerability in the safer_name_suffix() function in GNU cpio has been discovered.
A remote attacker could entice a user to open a specially crafted archive file resulting in a stack-based buffer overflow, possibly crashing the application. It is disputed whether the execution of arbitrary code is possible.
There is no known workaround at this time.
SolutionAll GNU cpio users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=app-arch/cpio-2.9-r1'
