WebP is a lossy image compression format.
An integer overflow flaw has been found in WebP.
A remote attacker could entice a user to open a specially crafted image in an application linked against WebP, possibly resulting in execution of arbitrary code with the privileges of the process or a Denial of Service condition.
There is no known workaround at this time.
All WebP users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=media-libs/libwebp-0.2.1"
