    Package        : openssl096
    Vulnerability  : denial of service (multiple)
    Problem-Type   : remote
    Debian-specific: no
    CVE ID         : CVE-2006-2940 CVE-2006-3738 CVE-2006-4343
    
    Multiple vulnerabilities have been discovered in the OpenSSL
    cryptographic software package that could allow an attacker to launch
    a denial of service attack by exhausting system resources or crashing
    processes on a victim's computer.
    
    CVE-2006-3738
            Tavis Ormandy and Will Drewry of the Google Security Team
            discovered a buffer overflow in SSL_get_shared_ciphers utility
            function, used by some applications such as exim and mysql.  An
            attacker could send a list of ciphers that would overrun a
            buffer.
    
    CVE-2006-4343
            Tavis Ormandy and Will Drewry of the Google Security Team
            discovered a possible DoS in the sslv2 client code.  Where a
            client application uses OpenSSL to make a SSLv2 connection to
            a malicious server that server could cause the client to
            crash.
    
    CVE-2006-2940
            Dr S N Henson of the OpenSSL core team and Open Network
            Security recently developed an ASN1 test suite for NISCC
            (www.niscc.gov.uk). When the test suite was run against
            OpenSSL a DoS was discovered.
    
            Certain types of public key can take disproportionate amounts
            of time to process. This could be used by an attacker in a
            denial of service attack.
    
    For the stable distribution (sarge) these problems have been fixed in
    version 0.9.6m-1sarge4
    
    This package exists only for compatibility with older software, and is
    not present in the unstable or testing branches of Debian.
    
    We recommend that you upgrade your openssl096 package.  Note that
    services linking against the openssl shared libraries will need to be
    restarted. Common examples of such services include most Mail
    Transport Agents, SSH servers, and web servers.
    
    
    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.
