cve-2020-12403

Vulnerability from cvelistv5

Published

2021-05-27 00:00

Modified

2024-08-04 11:56

Severity

Summary

A flaw was found in the way CHACHA20-POLY1305 was implemented in NSS in versions before 3.55. When using multi-part Chacha20, it could cause out-of-bounds reads. This issue was fixed by explicitly disabling multi-part ChaCha20 (which was not functioning correctly) and strictly enforcing tag length. The highest threat from this vulnerability is to confidentiality and system availability.
