SecurityTracker Alert ID:  1019497
SecurityTracker URL:  http://securitytracker.com/id/1019497
CVE Reference:   CVE-2008-0596, CVE-2008-0597   (Links to External Site)
Date:  Feb 25 2008
Impact:   Denial of service via network
Fix Available:  Yes  Vendor Confirmed:  Yes  

Description:   A vulnerability was reported in CUPS (Common UNIX Printing System). A remote user can cause denial of service conditions.

A remote user can send specially crafted IPP packets to cause the target CUPS service to crash.

A remote user can trigger a memory leak, causing the target daemon to consume all available memory and crash [CVE-2008-0596].

A remote user can add or remove shared printers to cause the target service to dereference already freed memory and crash [CVE-2008-0597].

These vulnerabilities were reported by Red Hat as affecting older versions of CUPS distributed with Red Hat Enterprise Linux.

Impact:   A remote user can cause the target service to crash.
Solution:   Red Hat has issued a fix for Red Hat Enterprise Linux.

The Red Hat advisories are available at:

A flaw was found in the way CUPS handled the addition and removal of remote
shared printers via IPP.  A remote attacker could send malicious UDP IPP
packets causing the CUPS daemon to attempt to dereference already freed
memory and crash. (CVE-2008-0597)

A memory management flaw was found in the way CUPS handled the addition and
removal of remote shared printers via IPP.  When shared printer was
removed, allocated memory was not properly freed, leading to a memory leak
possibly causing CUPS daemon crash after exhausting available memory.
(CVE-2008-0596)
