Please Install the Updated Packages.

The gcc and gcc4 packages include, among others, C, C++, and Java GNU compilers and related support libraries. libgcj contains a copy of GNU Libtool's libltdl library. A flaw was found in the way GNU Libtool's libltdl library looked for libraries to load. It was possible for libltdl to load a malicious library from the current working directory. In certain configurations, if a local attacker is able to trick a local user into running a Java application (which uses a function to load native libraries, such as System.loadLibrary) from within an attacker-controlled directory containing a malicious library or module, the attacker could possibly execute arbitrary code with the privileges of the user running the Java application. (CVE-2009-3736) All gcc and gcc4 users should upgrade to these updated packages, which contain a backported patch to correct this issue. All running Java applications using libgcj must be restarted for this update to take effect.
