GLSA-200511-03 : giflib: Multiple vulnerabilities
High Nessus Plugin ID 20153
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe remote host is affected by the vulnerability described in GLSA-200511-03 (giflib: Multiple vulnerabilities)
Chris Evans and Daniel Eisenbud independently discovered two out-of-bounds memory write operations and a NULL pointer dereference in giflib.
An attacker could craft a malicious GIF image and entice users to load it using an application making use of the giflib library, resulting in an application crash or potentially the execution of arbitrary code.
There is no known workaround at this time.
SolutionAll giflib users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=media-libs/giflib-4.1.4'
