Description
This security bulletin contains information about 1 security vulnerability.
1) Input validation error (CVE-ID: CVE-2013-0290)
The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.
The __skb_recv_datagram function in net/core/datagram.c in the Linux kernel before 3.8 does not properly handle the MSG_PEEK flag with zero-length data, which allows local users to cause a denial of service (infinite loop and system hang) via a crafted application.
Remediation
Install update from vendor's website.
