| Description: | 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: Tavis Ormandy reported a local DoS and potential privilege escalation in the Virtual Dynamic Shared Objects (vDSO) implementation. Eugene Teo reported a local DoS issue in the ext2 and ext3 filesystems. Local users who have been granted the privileges necessary to mount a filesystem would be able to craft a corrupted filesystem that causes the kernel to output error messages in an infinite loop. Milos Szeredi reported that the usage of splice() on files opened with O_APPEND allows users to write to the file at arbitrary offsets, enabling a bypass of possible assumed semantics of the O_APPEND flag. Vlad Yasevich reported an issue in the SCTP subsystem that may allow remote users to cause a local DoS by triggering a kernel oops. Eric Sesterhenn reported a local DoS issue in the hfsplus filesystem. Local users who have been granted the privileges necessary to mount a filesystem would be able to craft a corrupted filesystem that causes the kernel to overrun a buffer, resulting in a system oops or memory corruption. Eric Sesterhenn reported a local DoS issue in the hfsplus filesystem. Local users who have been granted the privileges necessary to mount a filesystem would be able to craft a corrupted filesystem that results in a kernel oops due to an unchecked return value. Eric Sesterhenn reported a local DoS issue in the hfs filesystem. Local users who have been granted the privileges necessary to mount a filesystem would be able to craft a filesystem with a corrupted catalog name length, resulting in a system oops or memory corruption. Andrea Bittau reported a DoS issue in the unix socket subsystem that allows a local user to cause memory corruption, resulting in a kernel panic. Hugo Dias reported a DoS condition in the ATM subsystem that can be triggered by a local user by calling the svc_listen function twice on the same socket and reading /proc/net/atm/*vc. Al Viro reported race conditions in the inotify subsystem that may allow local users to acquire elevated privileges. Dann Frazier reported a DoS condition that allows local users to cause the out of memory handler to kill off privileged processes or trigger soft lockups due to a starvation issue in the unix socket subsystem. |
