GLSA-200411-16 : zip: Path name buffer overflow
Critical Nessus Plugin ID 15691
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe remote host is affected by the vulnerability described in GLSA-200411-16 (zip: Path name buffer overflow)
zip does not check the resulting path length when doing recursive folder compression.
An attacker could exploit this by enticing another user or web application to create an archive including a specially crafted path name, potentially resulting in the execution of arbitrary code with the permissions of the user running zip.
There is no known workaround at this time.
SolutionAll zip users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=app-arch/zip-2.3-r4'
