"Diego Angulo from ImExHS discovered an issue in the webserver apache2.
The module mod_session ignored the expiry time of sessions handled by
mod_session_cookie, because the expiry time is available only after
decoding the session and the check was already done before.

For Debian 8 'Jessie', this problem has been fixed in version
2.4.10-10+deb8u13.

We recommend that you upgrade your apache2 packages.

NOTE: Tenable Network Security has extracted the preceding description
block directly from the DLA security advisory. Tenable has attempted
to automatically clean and format it as much as possible without
introducing additional issues.");
