Insight

Insight

NSS has shown timing differences when performing DSA signatures, which was exploitable and could eventually leak private keys. This vulnerability affects Thunderbird 68.9.0, Firefox 77, and Firefox ESR 68.9.(CVE-2020-12399) A flaw was found in the way CHACHA20-POLY1305 was implemented in NSS. 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(CVE-2020-12403) When converting coordinates from projective to affine, the modular inversion was not performed in constant time, resulting in a possible timing-based side channel attack. This vulnerability affects Firefox 80 and Firefox for Android 80.(CVE-2020-12400)
