Date Reported:
10 Jun 2016
Affected Packages:
Security database references:
In the Debian bugtracking system: Bug 824160.
In Mitre's CVE dictionary: CVE-2016-2335.
More information:

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.
