GLSA-201403-02 : LibYAML: Arbitrary code execution
Medium Nessus Plugin ID 72894
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe remote host is affected by the vulnerability described in GLSA-201403-02 (LibYAML: Arbitrary code execution)
A heap-based buffer overflow flaw was found in the way libyaml parsed YAML tags.
A remote attacker could provide a specially crafted YAML document which when parsed by LibYAML, would cause the application to crash or, potentially, execute arbitrary code with the privileges the user who is running the application.
There is no known workaround at this time.
SolutionAll LibYAML users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=dev-libs/libyaml-0.1.5'
