USN135-1 : gdb vulnerabilities Vulnerability Scan

Vulnerability Scan Summary
gdb vulnerabilities

Detailed Explanation for this Vulnerability Test

Synopsis :

The remote package "gdb" is missing a security patch.

Description :

Tavis Ormandy found an integer overflow in the GNU debugger. By
tricking an user into merely load a specially crafted executable, an
attacker could exploit this to execute arbitrary code with the
rights of the user running gdb. However, loading untrusted
binaries without actually executing them is rather uncommon, so the
risk of this flaw is low. (CVE-2005-1704)

Tavis Ormandy also discovered that gdb loads and executes the file
".gdbinit" in the current directory even if the file belongs to a
different user. By tricking an user into run gdb in a directory with a
malicious .gdbinit file, a local attacker could exploit this to run
arbitrary commands with the rights of the user invoking gdb.

Solution :

Upgrade to :
- gdb-6.3-5ubuntu1.1 (Ubuntu 5.04)

Threat Level: High
