Multiple Vendor CUPS CGI Heap Overflow Vulnerability
------------------------------------------------------------------------
SUMMARY
The Common UNIX Printing System, more commonly referred to as
<http://www.cups.org/> CUPS, "provides a standard printer interface for
various Unix based operating systems". Remote exploitation of a heap based
buffer overflow vulnerability in CUPS, as included in various vendors'
operating system distributions, could allow an attacker to execute
arbitrary code with the privileges of the affected service.
DETAILS
Vulnerable Systems:
* CUPS version 1.3.5
CUPS listens on TCP port 631 for requests. This interface provides access
to several CGI applications used to administer CUPS and provide
information about print jobs. By passing a specially crafted request, an
attacker can trigger a heap based buffer overflow.
Analysis:
Exploitation of this vulnerability results in the execution of arbitrary
code with the privileges of the affected service. Depending on the
underlying operating system and distribution, CUPS may run as the lp,
daemon, or a different user.
In order to exploit this vulnerability remotely, the targeted host must be
sharing a printer(s) on the network. If a printer is not being shared,
where CUPS only listens on the local interface, this vulnerability could
only be used to elevate privileges locally.
Workaround:
Disabling printer sharing will prevent this vulnerability from being
exploited remotely. However, local users will still be able to obtain the
privileges of the CUPS service user.
Vendor reponse:
Apple Inc. has addressed this vulnerability within Security Update
2008-002. For more information, visit the following URL.
