Red Hat Security Advisory
Synopsis: Low: gdb security and bug fix update
Advisory ID: RHSA-2007:0229-02
Advisory URL: https://rhn.redhat.com/errata/RHSA-2007-0229.html
Issue date: 2007-05-01
Updated on: 2007-05-01
Product: Red Hat Enterprise Linux
Keywords: stack buffer overflow dwarf
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 4 - i386, ia64, ppc, s390, s390x, x86_64
Red Hat Enterprise Linux Desktop version 4 - i386, x86_64
Red Hat Enterprise Linux ES version 4 - i386, ia64, x86_64
Red Hat Enterprise Linux WS version 4 - 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 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.
4. Solution:
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:

185337 - p errno does not work when stopped at a breakpoint
193763 - Buffer overrun in add_minsym_members
195429 - info threads crashes if zombie threads exist
202682 - print call foo where foo is in library SEGV
202689 - Cannot find user-level thread for LWP 4256: generic error
204841 - CVE-2006-4146 GDB buffer overflow
