TITLE:

SECUNIA ADVISORY ID:

VERIFY ADVISORY:
http://secunia.com/advisories/29431/

CRITICAL:
Moderately critical

IMPACT:
DoS, System access

WHERE:
>From local network

SOFTWARE:
CUPS 1.x
http://secunia.com/product/921/

DESCRIPTION:
A vulnerability has been reported in CUPS, which can be exploited by
malicious people to cause a DoS (Denial of Service) or to potentially
compromise a vulnerable system.

The vulnerability is caused due to an unspecified error within the
CUPS CGI backend. This can be exploited to cause a heap-based buffer
overflow via a specially crafted IPP request.

Successful exploitation may allow execution of arbitrary code, but
requires that the vulnerable system is sharing printers on the
network.

NOTE: If printer sharing is disabled, the vulnerability can only be
exploited by malicious, local users.

The vulnerability is reported in version 1.3.5. Other versions may
also be affected.

SOLUTION:
Restrict access to trusted users only. Disable printer sharing.
