Debian LTS: DLA-1971-1: libarchive security update
Summary
In case of a crafted archive containing several parts and one part being
corrupt, there would be an use-after-free for the next part of the
archive.
For Debian 8 "Jessie", this problem has been fixed in version
3.1.2-11+deb8u8.
We recommend that you upgrade your libarchive packages.
