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.
