Off-by-one buffer overflow in the sslcompatdirective function, as called by the rewritecommand hook for modssl Apache module 2.8.9 and earlier, allows local users to execute arbitrary code as the Apache server user via .htaccess files with long entries.

Format string vulnerability in the modproxy hook functions function in sslenginelog.c in modssl before 2.8.19 for Apache before 1.3.31 may allow remote attackers to execute arbitrary messages via format string specifiers in certain log messages for HTTPS that are handled by the ssllog function.

Cross-site scripting vulnerability in the modssl Apache module 2.8.9 and earlier, when UseCanonicalName is off and wildcard DNS is enabled, allows remote attackers to execute script as other web site visitors, via the server name in an HTTPS response on the SSL port, which is used in a self-referencing URL, a different vulnerability than CAN-2002-0840.
