    Package        : libapache-mod-ssl
    Vulnerability  : several
    Problem-Type   : remote
    Debian-specific: no
    CVE Ids        : CAN-2004-0488 CAN-2004-0700
    
    Two vulnerabilities were discovered in libapache-mod-ssl:
    
      CAN-2004-0488 - Stack-based buffer overflow in the
      ssl_util_uuencode_binary function in ssl_util.c for Apache mod_ssl,
      when mod_ssl is configured to trust the issuing CA, may allow remote
      attackers to execute arbitrary code via a client certificate with a
      long subject DN.
    
      CAN-2004-0700 - Format string vulnerability in the ssl_log function
      in ssl_engine_log.c in mod_ssl 2.8.19 for Apache 1.3.31 may allow
      remote attackers to execute arbitrary messages via format string
      specifiers in certain log messages for HTTPS.
    
    This is a revision to DSA 531-1, due to a problem with a documentation
    symlink in the previous version of the i386 binary package.
    
    For the current stable distribution (woody), these problems have been
    fixed in version 2.8.9-2.4.
    
    For the unstable distribution (sid), CAN-2004-0488 was fixed in
    version 2.8.18, and CAN-2004-0700 will be fixed soon.
    
    We recommend that you update your libapache-mod-ssl package.
