Please Install the Updated Packages.

The gcc packages include C, C++, Java, Fortran, Objective C, and Ada 95 GNU compilers, along with related support libraries. The libgcj package provides fastjar, an archive tool for Java Archive (JAR) files. Two directory traversal flaws were found in the way fastjar extracted JAR archive files. If a local, unsuspecting user extracted a specially-crafted JAR file, it could cause fastjar to overwrite arbitrary files writable by the user running fastjar. (CVE-2010-0831, CVE-2010-2322) This update also fixes the following bugs: * The option -print-multi-os-directory in the gcc --help output is not in the gcc(1) man page. This update applies an upstream patch to amend this. (BZ#529659) * An internal assertion in the compiler tried to check that a C++ static data member is external which resulted in errors. This was because when the compiler optimizes C++ anonymous namespaces the declarations were no longer marked external as everything on anonymous namespaces is local to the current translation. This update corrects the assertion to resolve this issue. (BZ#503565, BZ#508735, BZ#582682) * Attempting to compile certain .cpp files could have resulted in an internal compiler error. This update resolves this issue. (BZ#527510) * PrintServiceLookup.lookupPrintServices with an appropriate DocFlavor failed to return a list of printers under gcj. This update includes a backported patch to correct this bug in the printer lookup service. (BZ#578382) * GCC would not build against xulrunner-devel-1.9.2. This update removes gcjwebplugin from the GCC RPM. (BZ#596097) * When a SystemTap generated kernel module was compiled, gcc reported an internal compiler error and gets a segmentation fault. This update applies a patch that, instead of crashing, assumes it can point to anything. (BZ#605803) * There was a performance issue with libstdc++ regarding all objects derived from or using std::streambuf because of lock contention between threads. This patch ensures reload uses the same value from _S_global for the comparison, _M_add_reference () and _M_impl member of the class. (BZ#635708) All gcc users should upgrade to these updated packages, which contain backported patches to correct these issues.
