"Ed Moyle recently found a buffer overflow in Apache-SSL and mod_ssl.
With session caching enabled, mod_ssl will serialize SSL session
variables to store them for later use. These variables were stored in
a buffer of a fixed size without proper boundary checks.

To exploit the overflow, the server must be configured to require
client certificates, and an attacker must obtain a carefully crafted
client certificate that has been signed by a Certificate Authority
which is trusted by the server. If these conditions are met, it would
be possible for an attacker to execute arbitrary code on the server."

Debian distribution as well as in version 1.3.23.1+1.47-1 of
