"The fix for CVE-2016-8743 introduced a regression which would segfault
apache workers under certain conditions (#858373), an issue similar to
previously fixed CVE-2015-0253.

The issue was introduced in DLA-841-1 and the associated
2.2.22-13+deb7u8 package version. For Debian 7 'Wheezy', these
problems have been fixed in version 2.2.22-13+deb7u11.

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."
