"Several vulnerabilities have been discovered in Quagga, a routing
daemon.

  - CVE-2012-0249
    A buffer overflow in the ospf_ls_upd_list_lsa function
    in the OSPFv2 implementation allows remote attackers to
    cause a denial of service (assertion failure and daemon
    exit) via a Link State Update (aka LS Update) packet
    that is smaller than the length specified in its header.

  - CVE-2012-0250
    A buffer overflow in the OSPFv2 implementation allows
    remote attackers to cause a denial of service (daemon
    crash) via a Link State Update (aka LS Update) packet
    containing a network-LSA link-state advertisement for
    which the data-structure length is smaller than the
    value in the Length header field.

  - CVE-2012-0255
    The BGP implementation does not properly use message
    buffers for OPEN messages, which allows remote attackers
    impersonating a configured BGP peer to cause a denial of
    service (assertion failure and daemon exit) via a
    message associated with a malformed AS4 capability.

This security update upgrades the quagga package to the most recent
upstream release. This release includes other corrections, such as
hardening against unknown BGP path attributes."
