    Package        : dropbear
    Vulnerability  : buffer overflow
    Problem type   : local (remote)
    Debian-specific: no
    CVE ID         : CVE-2005-4178
    
    A buffer overflow has been discovered in dropbear, a lightweight SSH2
    server and client, that may allow authenticated users to execute
    arbitrary code as the server user (usually root).
    
    The old stable distribution (woody) does not contain dropbear packages.
    
    For the stable distribution (sarge) this problem has been fixed in
    version 0.45-2sarge0.
    
    For the unstable distribution (sid) this problem has been fixed in
    version 0.47-1.
    
    We recommend that you upgrade your dropbear package.
