Oracle Linux: CVE-2020-12403: ELSA-2021-0538: nss security and bug fix update (MODERATE) (Multiple Advisories)
Description
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. A flaw was found in the way CHACHA20-POLY1305 was implemented in NSS.
