CVE-2009-0859

Publication date 9 March 2009

Ubuntu priority

Low

Why this priority?

The shm_get_stat function in ipc/shm.c in the shm subsystem in the Linux kernel before 2.6.28.5, when CONFIG_SHMEM is disabled, misinterprets the data type of an inode, which allows local users to cause a denial of service (system hang) via an SHM_INFO shmctl call, as demonstrated by running the ipcs program.

From the Ubuntu Security Team

The shared memory subsystem did not correctly handle certain shmctl calls when CONFIG_SHMEM was disabled. Ubuntu kernels were not vulnerable, since CONFIG_SHMEM is enabled by default.
