    Debian Bug     : 526311
    
    It was discovered that Quagga, an IP routing daemon, could no longer
    process the Internet routing table due to broken handling of multiple
    4-byte AS numbers in an AS path.  If such a prefix is received, the
    BGP daemon crashes with an assert failure, leading to a denial of
    service.
    
    The old stable distribution (etch) is not affected by this issue.
    
    For the stable distribution (lenny), this problem has been fixed in
    version 0.99.10-1lenny2.
    
    For the unstable distribution (sid), this problem has been fixed in
    version 0.99.11-2.
    
    We recommend that you upgrade your quagga package.
