"Several remote vulnerabilities have been discovered in the BGP
implementation of Quagga, a routing daemon.

The Common Vulnerabilities and Exposures project identifies the
following problems :

  - CVE-2010-2948
    When processing a crafted Route Refresh message received
    from a configured, authenticated BGP neighbor, Quagga
    may crash, leading to a denial of service.

  - CVE-2010-2949
    When processing certain crafted AS paths, Quagga would
    crash with a NULL pointer dereference, leading to a
    denial of service. In some configurations, such crafted
    AS paths could be relayed by intermediate BGP routers.

In addition, this update contains a reliability fix: Quagga will no
longer advertise confederation-related AS paths to non-confederation
peers, and reject unexpected confederation-related AS paths by
resetting the session with the BGP peer which is advertising them.
(Previously, such AS paths would trigger resets of unrelated BGP
sessions.)"
