    Debian Bug     : 281922
    
    Several vulnerabilities have been discovered in unarj, a non-free ARJ
    unarchive utility.  The Common Vulnerabilities and Exposures Project
    identifies the following vulnerabilities:
    
    CAN-2004-0947
    
        A buffer overflow has been discovered when handling long file
        names contained in an archive.  An attacker could create a
        specially crafted archive which could cause unarj to crash or
        possibly execute arbitrary code when being extracted by a victim.
    
    CAN-2004-1027
    
        A directory traversal vulnerability has been found so that an
        attacker could create a specially crafted archive which would
        create files in the parent directory when being extracted by a
        victim.  When used recursively, this vulnerability could be used
        to overwrite critical system files and programs.
    
    For the stable distribution (woody) these problems have been fixed in
    version 2.43-3woody1.
    
    For the unstable distribution (sid) these problems don't apply since
    unstable/non-free does not contain the unarj package.
    
    We recommend that you upgrade your unarj package.
    
    
    Upgrade Instructions
    - --------------------
    
    wget url

    sources.list as given below:
    
    apt-get update
            will update the internal database

    footer to the proper configuration.
