Synopsis :

The remote Ubuntu host is missing one or more security-related patches.

Description :

It was discovered that the CUPS scheduler did not properly handle
certain network operations. A remote attacker could exploit this flaw
and cause the CUPS server to crash, resulting in a denial of service.
This issue only affected Ubuntu 8.04 LTS, 8.10, 9.04 and 9.10.
(CVE-2009-3553, CVE-2010-0302)

Ronald Volgers discovered that the CUPS lppasswd tool could be made to
load localized message strings from arbitrary files by setting an
environment variable. A local attacker could exploit this with a
format-string vulnerability leading to a root privilege escalation.
The default compiler options for Ubuntu 8.10, 9.04 and 9.10 should
reduce this vulnerability to a denial of service. (CVE-2010-0393).

Solution :

Update the affected packages.
