Description
This security bulletin contains information about 1 security vulnerability.
1) Race condition (CVE-ID: CVE-2014-0196)
The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.
The n_tty_write function in drivers/tty/n_tty.c in the Linux kernel through 3.14.3 does not properly manage tty driver access in the "LECHO & !OPOST" case, which allows local users to cause a denial of service (memory corruption and system crash) or gain privileges by triggering a race condition involving read and write operations with long strings.
Remediation
Install update from vendor's website.
