"It was discovered that there was a denial of service vulnerability in
the libarchive multi-format compression library. A specially crafted
.xar archive could cause via a heap-based buffer over-read.

For Debian 7 'Wheezy', this issue has been fixed in libarchive version
3.0.4-3+wheezy6+deb7u1.

We recommend that you upgrade your libarchive 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."
