Mandrake Linux Advisory: cups

May 29, 2003, 21:40 (0 Talkback[s])

Mandrake Linux Security Update Advisory


Package name: cups
Advisory ID: MDKSA-2003:062
Date: May 29th, 2003
Affected versions: 8.2, 9.0, 9.1, Corporate Server 2.1, Multi Network Firewall 8.2

Problem Description:

A Denial of Service (DoS) vulnerability was discovered in the CUPS printing system by Phil D'Amore of Red Hat. The IPP (Internet Printing Protocol) that CUPS uses is single-threaded and can only service one request at a time. A malicious user could create a partial request that does not time out and cause a Denial of Service condition where CUPS will not respond to other printing requests. This can only be done if the malicious user can create a TCP connection to the IPP port (631 by default).

This vulnerability has been fixed upstream in CUPS 1.1.19 and packages of previous versions have been fixed to correct the problem.
