Summary

Red Hat Security Advisory: gdb security and bug fix update

Severity

Low

Notes

Topic: An updated gdb package that fixes a security issue and various bugs is now available. This update has been rated as having low security impact by the Red Hat Security Response Team.

Details: 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.

CVE-2006-4146

Buffer overflow in the (1) DWARF (dwarfread.c) and (2) DWARF2 (dwarf2read.c) debugging code in GNU Debugger (GDB) 6.5 allows user-assisted attackers, or restricted users, to execute arbitrary code via a crafted file with a location block (DW_FORM_block) that contains a large number of operations.

Vendor Fix Before applying this update, make sure that all previously-released errata relevant to your system have been applied. Use Red Hat Network to download and update your packages. To launch the Red Hat Update Agent, use the following command: up2date For information on how to install packages manually, refer to the following Web page for the System Administration or Customization guide specific to your system: http://www.redhat.com/docs/manuals/enterprise/ https://access.redhat.com/errata/RHSA-2007:0229
