Package : p7zip
Version : 9.20.1~dfsg.1-4+deb7u3
CVE ID : CVE-2017-17969
Debian Bug : 888297

The p7zip package has a heap-based buffer overflow in the
NCompress::NShrink::CDecoder::CodeReal method in 7-Zip which allows
remote attackers to cause a denial of service (out-of-bounds write) or
potentially execute arbitrary code via a crafted ZIP archive.

For Debian 7 "Wheezy", these problems have been fixed in version
9.20.1~dfsg.1-4+deb7u3.

We recommend that you upgrade your p7zip packages.
