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 the stable distribution (jessie), this problem has been fixed in version 9.20.1~dfsg.1-4.1+deb8u2.

For the testing distribution (stretch), this problem has been fixed in version 15.14.1+dfsg-2.

For the unstable distribution (sid), this problem has been fixed in version 15.14.1+dfsg-2.

We recommend that you upgrade your p7zip packages.
