"debian-security-support, the Debian security support coverage checker,
has been updated in jessie-security.

This marks the end of life of the libqb package in jessie. A recently
reported vulnerability against libqb which allows users to overwrite
arbitrary files via a symlink attack cannot be adequately addressed in
libqb in jessie. Upstream no longer supports this version and no
packages in jessie depend upon libqb.

We recommend that if your systems or applications depend upon the
libqb package provided from the Debian archive that you upgrade your
systems to a more recent Debian release or find an alternate and up to
date source of libqb packages.

Additionally, MySQL 5.5 is no longer supported. Upstream has ended its
support and we are unable to backport fixes from newer versions due to
the lack of patch details. Options are to switch to MariaDB 10.0 in
jessie or to a newer version of MySQL in more recent Debian releases.

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."
