"Marcin 'Icewall' Noga of Cisco Talos discovered an out-of-bound read
vulnerability in the CInArchive::ReadFileItem method in p7zip, a 7zr
file archiver with high compression ratio. A remote attacker can take
advantage of this flaw to cause a denial of service or, potentially
the execution of arbitrary code with the privileges of the user
running p7zip, if a specially crafted UDF file is processed.

For Debian 7 'Wheezy', these problems have been fixed in version
9.20.1~dfsg.1-4+deb7u2.

We recommend that you upgrade your p7zip 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."
