Two vulnerabilities have been reported in Apache httpd, which can be exploited by malicious people to cause a DoS (Denial of Service).

1) An error within the "ap_get_mime_headers_core()" function when processing headers can be exploited to consume all available memory via specially crafted, overly long header lines starting with either a TAB or SPACE character.

This vulnerability has been reported in versions 2.0.46 through 2.0.49. Prior versions may also be affected.

2) An error within the "ssl_io_filter_cleanup()" function can be exploited to cause a crash by sending a SSL request and then closing the connection down immediately.

This vulnerability has been reported in versions prior to version 2.0.50.

Solution
Update to version 2.0.50.
