Test ID:1.3.6.1.4.1.25623.1.0.68268
Category:Mandrake Local Security Checks
Title:Mandriva Security Advisory MDVSA-2010:172 (kernel)
Summary:Mandriva Security Advisory MDVSA-2010:172 (kernel)
Description:The remote host is missing an update to kernel
announced via advisory MDVSA-2010:172.

Some vulnerabilities were discovered and corrected in the Linux
2.6 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 (system crash) via unspecified
vectors. (CVE-2010-2492)

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. (CVE-2010-2524)

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. (CVE-2010-2240)

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 (BUG and system crash) via a
write operation on the last block of a large file, followed by a sync
operation. (CVE-2010-3015)

To update your kernel, please follow the directions located at:

http://www.mandriva.com/en/security/kernelupdate

Affected: 2010.1

Solution:
To upgrade automatically use MandrakeUpdate or urpmi. The verification
of md5 checksums and GPG signatures is performed automatically for you.
