Ubuntu 4.10 / 5.04 : gdb vulnerabilities (USN-135-1)

Ubuntu Security Notice (C) 2005-2016 Canonical, Inc. / NASL script (C) 2006-2016 Tenable Network Security, Inc.


Synopsis :

The remote Ubuntu host is missing a security-related 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
privileges of the user running gdb. However, loading untrusted
binaries without actually executing them is rather uncommon, so the
risk of this flaw is low. (CAN-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 privileges of the user invoking gdb.
(CAN-2005-1705).

Note that Tenable Network Security has extracted the preceding
description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.

Solution :

Update the affected gdb package.

Risk factor :

High / CVSS Base Score : 7.2
(CVSS2#AV:L/AC:L/Au:N/C:C/I:C/A:C)
