Apache-SSL buffer overflow (fix available)
From: Ben Laurie <ben () algroup co uk>

Apache-SSL buffer overflow condition (all versions prior to 1.3.22+1.46)
------------------------------------------------------------------------

Synopsis
--------

A buffer overflow was recently found in mod_ssl, see:

http://archives.neohapsis.com/archives/bugtraq/2002-02/0313.html

for details. The offending code in mod_ssl was, in fact, derived from
Apache-SSL, and Apache-SSL is also vulnerable.

As in mod_ssl, this flaw can only be exploited if client certificates
are being used, and the certificate in question must be issued by a
trusted CA.

Fix
---

Download Apache-SSL 1.3.22+1.46 from the usual places (see
http://www.apache-ssl.org/).

Acknowledgements
----------------

Thanks to Ed Moyle for finding the flaw.

Rant
----

No thanks to anyone at all for alerting me before going
public. Cheers, guys.
