Description
This security bulletin contains information about 1 security vulnerability.
1) Cryptographic issues (CVE-ID: CVE-2014-0102)
The vulnerability allows a remote #AU# to perform a denial of service (DoS) attack.
The keyring_detect_cycle_iterator function in security/keys/keyring.c in the Linux kernel through 3.13.6 does not properly determine whether keyrings are identical, which allows local users to cause a denial of service (OOPS) via crafted keyctl commands.
Remediation
