CVE-2009-0859

Priority
Description
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.
Ubuntu-Description
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.
