GLSA-200907-01 : libwmf: User-assisted execution of arbitrary code
High Nessus Plugin ID 39595
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe remote host is affected by the vulnerability described in GLSA-200907-01 (libwmf: User-assisted execution of arbitrary code)
The embedded fork of the GD library introduced a 'use-after-free' vulnerability in a modification which is specific to libwmf.
A remote attacker could entice a user to open a specially crafted WMF file, possibly resulting in the execution of arbitrary code with the privileges of the user running the application, or a Denial of Service.
There is no known workaround at this time.
SolutionAll libwmf users should upgrade to the latest version which no longer builds the GD library:
# emerge --sync # emerge --ask --oneshot --verbose '>=media-libs/libwmf-0.2.8.4-r3'
