+ libpng contains numerous vulnerabilities including null pointer dereference
+ errors and boundary errors in various functions.

+ </description>
+ <impact type="normal">
+ <p>
+ An attacker could exploit these vulnerabilities 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-r8"
+ # emerge ">=media-libs/libpng-1.2.5-r8"</code>
+ <p>
+ You should also run revdep-rebuild to rebuild any packages that depend on
+ older versions of libpng :
+ </p>
+ <code>
+ # revdep-rebuild</code>
