CVE-2018-1324

This can be used to mount a denial of service attack against services that use Compress' zip package.

MEDIUM 5.5EPSS 3.66%

Does this matter?

Lower severity and a low EPSS score (3.66%). Track it; it rarely justifies an emergency change on its own.

Description

A specially crafted ZIP archive can be used to cause an infinite loop inside of Apache Commons Compress' extra field parser used by the ZipFile and ZipArchiveInputStream classes in versions 1.11 to 1.15. This can be used to mount a denial of service attack against services that use Compress' zip package.
