    Debian-specific: no
    CVE ID         : CAN-2005-1848
    
    "infamous42md" discovered that dhcpcd, a DHCP client for automatically
    configuring IPv4 networking, can be tricked into reading past the end
    of the supplied DHCP buffer which could lead to the daemon crashing.
    
    The old stable distribution (woody) is not affected by this problem.
    
    For the stable distribution (sarge) this problem has been fixed in
    version 1.3.22pl4-21sarge1.
    
    For the unstable distribution (sid) this problem has been fixed in
    version 1.3.22pl4-22.
    
    We recommend that you upgrade your dhcpcd package.
