TITLE:
Apache 2 mod_ssl Connection Abort Denial of Service

SECUNIA ADVISORY ID:
SA12434

VERIFY ADVISORY:
http://secunia.com/advisories/12434/

CRITICAL:
Less critical

IMPACT:
DoS

WHERE:
From remote

SOFTWARE:
Apache 2.0.x
http://secunia.com/product/73/

DESCRIPTION:
A vulnerability has been reported in Apache 2 mod_ssl, which can be
exploited by malicious people to cause a DoS (Denial of Service).

The problem is that it is possible to cause mod_ssl to enter an
infinite loop by aborting a SSL connection in a particular state.
This causes the process to consume large amounts of CPU resources.

This has been reported in Apache 2.0.50 and prior.

SOLUTION:
Use another product to provide SSL support.

PROVIDED AND/OR DISCOVERED BY:
Reported in a Red Hat advisory.
