6b36ec4068d40a47c3a69616c6e9e4c23c26d91d6ae30534472022bde895c2ccMandriva Linux Security Advisory 2010-172 - Some vulnerabilities were discovered and corrected in the Linux kernel. Buffer overflow in the ecryptfs_uid_hash macro in fs/ecryptfs/messaging.c in the eCryptfs subsystem in the Linux kernel before 2.6.35 might allow local users to gain privileges or cause a denial of service via unspecified vectors. The DNS resolution functionality in the CIFS implementation in the Linux kernel before 2.6.35, when CONFIG_CIFS_DFS_UPCALL is enabled, relies on a user's keyring for the dns_resolver upcall in the cifs.upcall userspace helper, which allows local users to spoof the results of DNS queries and perform arbitrary CIFS mounts via vectors involving an add_key call, related to a cache stuffing issue and MS-DFS referrals. The do_anonymous_page function in mm/memory.c in the Linux kernel before 2.6.27.52, 2.6.32.x before 2.6.32.19, 2.6.34.x before 2.6.34.4, and 2.6.35.x before 2.6.35.2 does not properly separate the stack and the heap, which allows context-dependent attackers to execute arbitrary code by writing to the bottom page of a shared memory segment, as demonstrated by a memory-exhaustion attack against the X.Org X server. Integer overflow in the ext4_ext_get_blocks function in fs/ext4/extents.c in the Linux kernel before 2.6.34 allows local users to cause a denial of service via a write operation on the last block of a large file, followed by a sync operation.
