CVE-2010-2524 (GCVE-0-2010-2524)

Vulnerability from cvelistv5 – Published: 2010-09-08 19:00 – Updated: 2024-08-07 02:39

Summary

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.
