Package        : libapache-mod-ssl
Problem type   : buffer overflow / DoS
Debian-specific: no

The libapache-mod-ssl package provides SSL capability to the apache
webserver.
Recently, a problem has been found in the handling of .htaccess files,
allowing arbitrary code execution as the web server user (regardless of
ExecCGI / suexec settings), DoS attacks (killing off apache children), and
allowing someone to take control of apache child processes - all trough
specially crafted .htaccess files.
More information about this vulnerability can be found at
 
http://online.securityfocus.com/bid/5084

This has been fixed in the libapache-mod-ssl_2.4.10-1.3.9-1potato2 package
(for potato), and the libapache-mod-ssl_2.8.9-2 package (for woody) .
We recommend you upgrade as soon as possible.
