Description:   Two vulnerabilities were reported in 7-Zip. A remote user can cause arbitrary code to be executed on the target user's system.

The code will run with the privileges of the target application [CVE-2018-5996].

A remote user can create a specially crafted ZIP archive file that, when processed by the target application, will trigger a heap overflow in the LZW compression algorithm implementation (Shrink) and execute arbitrary code on the target system. The code will run with the privileges of the target application [CVE-2017-17969].
