Insight
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)
