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."
