+ <title>libpng: Buffer overflow</title>
+ <synopsis>
+ A buffer overflow has been found in the libpng library that could lead to
+ the execution of arbitrary code.

+ <background>
+ <p>
+ libpng is an open, extensible image format library, with lossless
+ compression.
+ </p>
+ </background>
+ <description>
+ <p>
+ In pngrutil.c, the function png_decompress_chunk() allocates
+ insufficient space for an error message, potentially overwriting stack
+ data, leading to a buffer overflow.
+ </p>
+ </description>
+ <impact type="normal">
+ <p>
+ By enticing a user to load a maliciously crafted PNG image, an attacker
+ could execute arbitrary code with the rights of the user, or crash the
+ application using the libpng library, such as the
+ emul-linux-x86-baselibs.
+ </p>
+ </impact>
+ <workaround>
+ <p>
+ There is no known workaround at this time.
+ </p>
+ </workaround>
+ <resolution>
+ <p>
+ All libpng users should upgrade to the latest version:
+ </p>
+ <code>
+ # emerge --sync
+ # emerge --ask --oneshot --verbose &quot;&gt;=media-libs/libpng-1.2.12&quot;</code>
+ <p>
+ All AMD64 emul-linux-x86-baselibs users should also upgrade to the
+ latest version:
+ </p>
+ <code>
+ # emerge --sync
+ # emerge --ask --oneshot --verbose &quot;&gt;=app-emulation/emul-linux-x86-baselibs-2.5.1&quot;</code>
