    CVE ID         : CVE-2010-1674 CVE-2010-1675
    
    It has been discovered that the Quagga routing daemon contains two
    denial-of-service vulnerabilities in its BGP implementation:
    
    CVE-2010-1674
    	A crafted Extended Communities attribute triggers a null
            pointer dereference which causes the BGP daemon to crash.
    	The crafted attributes are not propagated by the Internet
    	core, so only explicitly configured direct peers are able
    	to exploit this vulnerability in typical configurations.
    
    CVE-2010-1675
    	The BGP daemon resets BGP sessions when it encounters
    	malformed AS_PATHLIMIT attributes, introducing a distributed
    	BGP session reset vulnerability which disrupts packet
    	forwarding.  Such malformed attributes are propagated by the
    	Internet core, and exploitation of this vulnerability is not
    	restricted to directly configured BGP peers.
    
    This security update removes AS_PATHLIMIT processing from the BGP
    implementation, preserving the configuration statements for backwards
    compatibility.  (Standardization of this BGP extension was abandoned
    long ago.)
    
    For the oldstable distribution (lenny), these problems have been fixed
    in version 0.99.10-1lenny5.
    
    For the stable distribution (squeeze), these problems have been fixed
    in version 0.99.17-2+squeeze2.
    
    For the testing distribution (wheezy) and the unstable distribution
    (sid), these problems will fixed soon.
    
    We recommend that you upgrade your quagga packages.
