    Package        : openssl
    Vulnerability  : denial of service
    Problem-Type   : remote
    Debian-specific: no
    CVE Ids        : CAN-2003-0543 CAN-2003-0544
    
    Dr. Stephen Henson (This email address is being protected from spambots. You need JavaScript enabled to view it.), using a test suite provided by
    NISCC (www.niscc.gov.uk), discovered a number of errors in the OpenSSL
    ASN1 code.  Combined with an error that causes the OpenSSL code to parse
    client certificates even when it should not, these errors can cause a
    denial of service (DoS) condition on a system using the OpenSSL code, 
    depending on how that code is used. For example, even though apache-ssl
    and ssh link to OpenSSL libraries, they should not be affected by this
    vulnerability. However, other SSL-enabled applications may be
    vulnerable and an OpenSSL upgrade is recommended.
    
    For the current stable distribution (woody) these problems have been
    fixed in version 0.9.6c-2.woody.4
    
    For the unstable distribution (sid) these problems have been fixed in
    version 0.9.7c-1
    
    We recommend that you update your openssl package. Note that you will
    need to restart services which use the libssl library for this update
    to take effect.
    
    Upgrade Instructions
    - --------------------
    
    wget url
            will fetch the file for you
    dpkg -i file.deb
            will install the referenced file.
    
    If you are using the apt-get package manager, use the line for
    sources.list as given below:
    
    apt-get update
            will update the internal database
    apt-get upgrade
            will install corrected packages
    
    You may use an automated update by adding the resources from the
    footer to the proper configuration.
