"Upstream published version 0.98.5. This update updates sqeeze-lts to
the latest upstream release in line with the approach used for other
Debian releases.

This update corrects a double-free error that existed within the
'unrar_extract_next_prepare()' function
(libclamunrar_iface/unrar_iface.c) when parsing a RAR file. While no
CVE was assigned, this issue does have potential security
implications.

If you use libclamunrar, we strongly recommend that you upgrade to
this version.

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."
