CVE-2010-1437 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2010-1437): Race condition in the find_keyring_by_name function in security/keys/keyring.c in the Linux kernel 2.6.34-rc5 and earlier allows local users to cause a denial of service (memory corruption and system crash) or possibly have unspecified other impact via keyctl session commands that trigger access to a dead keyring that is undergoing deletion by the key_cleanup function. Of the hardened sources currently in the tree, none of the hardened-sources-2.6.32* are vulnerable. They are based off of kernels > 2.6.32.10. |
