CVE-2017-17969 (opens in a new tab)Amendment
The Ubuntu security team deemed this advisory irrelevant for Ubuntu:18.10.
NVD Description
Note: Versions mentioned in the description apply only to the upstream p7zip package and not the p7zip package as distributed by Ubuntu.
Heap-based buffer overflow in the NCompress::NShrink::CDecoder::CodeReal method in 7-Zip before 18.00 and p7zip allows remote attackers to cause a denial of service (out-of-bounds write) or potentially execute arbitrary code via a crafted ZIP archive.
