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.

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)
