Description

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