Vendor Advisories

Igor Zhbanov discovered that NFS clients were able to create device nodes even when root_squash was enabled An authenticated remote attacker could create device nodes with open permissions, leading to a loss of privacy or escalation of privileges Only Ubuntu 810 and 904 were affected (CVE-2009-1072) ...
Several vulnerabilities have been discovered in the Linux kernel that may lead to a denial of service or privilege escalation The Common Vulnerabilities and Exposures project identifies the following problems: CVE-2009-1385 Neil Horman discovered a missing fix from the e1000 network driver A remote user may cause a denial of service by w ...
