|Description||The shm_get_stat function in ipc/shm.c in the shm subsystem in the Linux kernel before 184.108.40.206, 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.|
|Source||CVE (at NVD; oss-sec, fulldisc, OSVDB, EDB, Metasploit, Red Hat, Ubuntu, Gentoo, SuSE, Mageia, more)|
|References||DSA-1787-1, DSA-1794-1, DSA-1800-1|

Vulnerable and fixed packages
The table below lists information on source packages.
|linux-2.6 (PTS)||squeeze (security), squeeze||2.6.32-48squeeze6||fixed|
The information above is based on the following data on fixed versions.
All Debian kernels set CONFIG_SHMEM, so this is moot except
for locally modified configs and even for that I fail to
see why anyone would run a kernel w/o CONFIG_SHMEM?
