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.

Summary: Multiple kernel flaws.
Dan Rosenberg discovered that the RDS network protocol did not correctly
check certain parameters. A local attacker could exploit this gain root
privileges. (CVE-2010-3904)
Nelson Elhage discovered several problems with the Acorn Econet protocol
driver. A local user could cause a denial of service via a NULL pointer
dereference, escalate privileges by overflowing the kernel stack, and
assign Econet addresses to arbitrary interfaces. (CVE-2010-3848,

Ben Hawkes discovered that the Linux kernel did not correctly filter
registers on 64bit kernels when performing 32bit system calls. On a 64bit

kernel: dns_resolver upcall security issue
vendor_redhat·2010-07-22·CVSS 7.8
CVE-2010-2524 [HIGH] kernel: dns_resolver upcall security issue
kernel: dns_resolver upcall security issue
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.
Statement: This issue did not affect the versions of the Linux kernel as shipped with Red Hat Enterprise Linux 3, 4, and Red Hat Enterprise MRG as they did not include support for the upcall mechanism for the Common Internet File System (CIFS). This issue was addressed in Red Hat Enterprise Linux 5 via https://rhn.redhat.com/errata/RH
