Description
This security bulletin contains information about 1 security vulnerability.
1) Input validation error (CVE-ID: CVE-2014-2673)
The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.
The arch_dup_task_struct function in the Transactional Memory (TM) implementation in arch/powerpc/kernel/process.c in the Linux kernel before 3.13.7 on the powerpc platform does not properly interact with the clone and fork system calls, which allows local users to cause a denial of service (Program Check and system crash) via certain instructions that are executed with the processor in the Transactional state.
Remediation
Install update from vendor's website.
