RedHat: Low: gdb security and bug fix update
Summary
Summary
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.
