RHEL 4 : gdb (RHSA-2005:709)

high Nessus Plugin ID 19994

Synopsis

The remote Red Hat host is missing one or more security updates for gdb.

Description

The remote Redhat Enterprise Linux 4 host has a package installed that is affected by multiple vulnerabilities as referenced in the RHSA-2005:709 advisory.

GDB, the GNU debugger, allows debugging of programs written in C, C++, and other languages by executing them in a controlled fashion, then printing their data.

Several integer overflow bugs were found in gdb. If a user is tricked into processing a specially crafted executable file, it may allow the execution of arbitrary code as the user running gdb. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2005-1704 to this issue.

A bug was found in the way gdb loads .gdbinit files. When a user executes gdb, the local directory is searched for a .gdbinit file which is then loaded. It is possible for a local user to execute arbitrary commands as the victim running gdb by placing a malicious .gdbinit file in a location where gdb may be run. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2005-1705 to this issue.

This updated package also addresses the following issues:

- GDB on ia64 had previously implemented a bug fix to work-around a kernel problem when creating a core file via gcore. The bug fix caused a significant slow-down of gcore.

- GDB on ia64 issued an extraneous warning when gcore was used.

- GDB on ia64 could not backtrace over a sigaltstack.

- GDB on ia64 could not successfully do an info frame for a signal trampoline.

- GDB on AMD64 and Intel EM64T had problems attaching to a 32-bit process.

- GDB on AMD64 and Intel EM64T was not properly handling threaded watchpoints.

- GDB could not build with gcc4 when -Werror flag was set.

- GDB had problems printing inherited members of C++ classes.

- A few updates from mainline sources concerning Dwarf2 partial die in cache support, follow-fork support, interrupted syscall support, and DW_OP_piece read support.

All users of gdb should upgrade to this updated package, which resolves these issues.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the RHEL gdb package based on the guidance in RHSA-2005:709.
