Subject: CVE-2021-35515: Apache Commons Compress 1.6 to 1.20 denial of
 service vulnerability 

Severity: low


When reading a specially crafted 7Z archive, the construction of the list of codecs that decompress an entry can result in an infinite loop.  This could be used to mount a denial of service attack against services that use Compress' sevenz package.


Commons Compress users should upgrade to 1.21 or later.


This issue was discovered by OSS Fuzz.
