CESA-2007:0469: gdb security and bug fix update
Description
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 CentOS Security Response Team.
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 an attacker could trick a user into loading an executable containing malicious debugging information into GDB, they may be able to execute arbitrary code with the privileges of the user. (CVE-2006-4146) This updated package also addresses the following issues: * Support on 64-bit hosts shared libraries debuginfo larger than 2GB. * Fix a race occasionally leaving the detached processes stopped. * Fix segmentation fault on the source display by ^X 1. * Fix a crash on an opaque type dereference. All users of gdb should upgrade to this updated package, which contains backported patches to resolve these issues.
