==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 12.04 LTS
- Ubuntu 11.10
- Ubuntu 11.04
- Ubuntu 10.04 LTS

Summary:

Quagga could be made to crash if it received specially crafted network
traffic.

Software Description:
- quagga: BGP/OSPF/RIP routing daemon

Details:

It was discovered that Quagga incorrectly handled Link State Update
messages with invalid lengths. A remote attacker could use this flaw to
cause Quagga to crash, resulting in a denial of service. (CVE-2012-0249,
CVE-2012-0250)

It was discovered that Quagga incorrectly handled messages with a malformed
Four-octet AS Number Capability. A remote attacker could use this flaw to
cause Quagga to crash, resulting in a denial of service. (CVE-2012-0255)

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 12.04 LTS:
  quagga                          0.99.20.1-0ubuntu0.12.04.2

Ubuntu 11.10:
  quagga                          0.99.20.1-0ubuntu0.11.10.2

Ubuntu 11.04:
  quagga                          0.99.20.1-0ubuntu0.11.04.2

Ubuntu 10.04 LTS:
  quagga                          0.99.20.1-0ubuntu0.10.04.2

all the necessary changes.
