+ <p>
+ libpng is a standard library used to process PNG (Portable Network
+ Graphics) images. It is used by several other programs, including web
+ browsers and potentially server processes.
+ </p>
+ </background>
+ <description>
+ <p>
+ Due to a wrong calculation of loop offset values, libpng contains a buffer
+ overflow vulnerability on the row buffers. This vulnerability was initially
+ patched in January 2003 but since it has been discovered that libpng
+ contains the same vulnerability in two other places.
+ </p>
+ </description>
+ <impact type="normal">
+ <p>
+ An attacker could exploit this vulnerability to cause programs linked
+ against the library to crash or execute arbitrary code with the permissions
+ of the user running the vulnerable program, which could be the root user.
+ </p>
+ </impact>
+ <workaround>
+ <p>
+ There is no known workaround at this time. All users are encouraged to
+ upgrade to the latest available version.
+ </p>
+ </workaround>
+ <resolution>
+ <p>
+ All libpng users should upgrade to the latest stable version:
+ </p>
+ <code>
+ # emerge sync
+
+ # emerge -pv ">=media-libs/libpng-1.2.5-r7"
+ # emerge ">=media-libs/libpng-1.2.5-r7"</code>
+ <p>
+ You should also run revdep-rebuild to rebuild any packages that depend on
+ older versions of libpng :
+ </p>
+ <code>
+ # revdep-rebuild</code>
