RHSA-2007:0229: gdb security and bug fix update (Low)  

GDB, the GNU debugger, allows debugging of programs written in C, C++, and other languages by executing them in a controlled fashion and then printing their data.
Various buffer overflows and underflows were found in the DWARF expression computation stack in GDB. If a user loaded an executable containing malicious debugging information into GDB, an attacker might be able to execute arbitrary code with the privileges of the user. (CVE-2006-4146)
This updated package also addresses the following issues:
* Fixed bogus 0x0 unwind of the thread's topmost function clone(3).
* Fixed deadlock accessing invalid address; for corrupted backtraces.
* Fixed a race which occasionally left the detached processes stopped.
* Fixed 'gcore' command for 32bit debugged processes on 64bit hosts.
* Added support for TLS 'errno' for threaded programs missing its '-debuginfo' package..
* Suggest TLS 'errno' resolving by hand if no threading was found..
* Added a fix to prevent stepping into asynchronously invoked signal handlers.
* Added a fix to avoid false warning on shared objects bfd close on Itanium.
* Fixed segmentation fault on the source display by ^X 1.
* Fixed object names keyboard completion.
* Added a fix to avoid crash of 'info threads' if stale threads exist.
* Fixed a bug where shared libraries occasionally failed to load .
* Fixed handling of exec() called by a threaded debugged program.
* Fixed rebuilding requirements of the gdb package itself on multilib systems.
* Fixed source directory pathname detection for the edit command.
All users of gdb should upgrade to this updated package, which contains backported patches to resolve these issues.
