Package        : quagga
Vulnerability  : several
Problem type   : remote
Debian-specific: no
CVE Id(s)      : CVE-2010-2948 CVE-2010-2949
Debian Bug     : 594262

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.)

For the stable distribution (lenny), these problems have been fixed in
version 0.99.10-1lenny3.

For the unstable distribution (sid) and the testing distribution
(squeeze), these problems have been fixed in version 0.99.17-1.

We recommend that you upgrade your quagga package.
