Here is the official description of the vulnerability:
Incorrect initialization logic of RAR decoder objects in 7-Zip 18.03 and before can lead to usage of uninitialized memory, allowing remote attackers to cause a denial of service (segmentation fault) or execute arbitrary code via a crafted RAR archive.
As just mentioned, successful exploitation of this vulnerability could allow attackers to perform arbitrary code execution on vulnerable systems.
