Details
Stephan Mueller reported a flaw in the Linux kernel's dl2k network driver's
handling of ioctls. An unprivileged local user could leverage this flaw to
cause a denial of service. (CVE-2012-2313)
Timo Warns reported multiple flaws in the Linux kernel's hfsplus
filesystem. An unprivileged local user could exploit these flaws to gain
root system priviliges. (CVE-2012-2319)
A flaw was discovered in the Linux kernel's NFSv4 (Network file system)
handling of ACLs (access control lists). A remote NFS server (attacker)
could cause a denial of service (OOPS). (CVE-2012-2375)
