+ <title>giflib: Multiple vulnerabilities</title>
+ <synopsis>
+ giflib may dereference NULL or write out of bounds when processing
+ malformed images, potentially resulting in Denial of Service or arbitrary
+ code execution.

+ <background>
+ <p>
+ giflib is a library for reading and writing GIF images.
+ </p>

+ <description>
+ <p>
+ Chris Evans and Daniel Eisenbud independently discovered two
+ out-of-bounds memory write operations and a NULL pointer dereference in
+ giflib.
+ </p>
+ </description>
+ <impact type="normal">
+ <p>
+ 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.
+ </p>
+ </impact>
+ <workaround>
+ <p>
+ There is no known workaround at this time.
+ </p>
+ </workaround>
+ <resolution>
+ <p>
+ All giflib users should upgrade to the latest version:
+ </p>
+ <code>
+ # emerge --sync
+ # emerge --ask --oneshot --verbose "&gt;=media-libs/giflib-4.1.4"</code>
