"The security update announced as DLA-924-1 introduced a regression in
Tomcat's APR protocol due to the fix for CVE-2017-5647 and prevented a
successful sendfile request.

For Debian 7 'Wheezy', these problems have been fixed in version
7.0.28-4+deb7u13.

We recommend that you upgrade your tomcat7 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."
