Description

This security bulletin contains information about 2 secuirty vulnerabilities.


1) Resource exhaustion (CVE-ID: CVE-2010-4251)

The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.

The socket implementation in net/core/sock.c in the Linux kernel before 2.6.34 does not properly manage a backlog of received packets, which allows remote attackers to cause a denial of service (memory consumption) by sending a large amount of network traffic, as demonstrated by netperf UDP tests.


2) NULL pointer dereference (CVE-ID: CVE-2010-4263)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a NULL pointer dereference error. A remote attacker can trigger denial of service conditions via a VLAN tagged frame.
