CVE Names: CVE-2006-4146
- ---------------------------------------------------------------------
1. Summary:
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.
2. Relevant releases/architectures:
Red Hat Enterprise Linux AS version 3 - i386, ia64, ppc, s390, s390x, x86_64
Red Hat Desktop version 3 - i386, x86_64
Red Hat Enterprise Linux ES version 3 - i386, ia64, x86_64
Red Hat Enterprise Linux WS version 3 - i386, ia64, x86_64
3. Problem description:
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.
