    Package        : syslog-ng
    Vulnerability  : buffer overflow
    Problem-Type   : remote
    Debian-specific: no
    
    Péter Höltzl discovered a problem in the way syslog-ng handles macro
    expansion.  When a macro is expanded a static length buffer is used
    accompanied by a counter.  However, when constant chharacters are
    appended, the counter is not updated properly, leading to incorrect
    boundary checking.  An attacker may be able to use specially crafted
    log messages inserted via UDP which overflows the buffer.
    
    This problem has been fixed in version 1.5.15-1.1 for the current
    stable distribution (woody), in version 1.4.0rc3-3.2 for the old
    stable distribution (potato) and version 1.5.21-1 for the unstable
    distribution (sid).
    
    We recommend that you upgrade your syslog-ng package immediately.
    
    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.
