Synopsis
The remote Oracle Linux host is missing one or more security updates.Description
The remote Oracle Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2021-0538 advisory.- nss: CHACHA20-POLY1305 decryption with undersized tag leads to out-of-bounds read (CVE-2020-12403)
- When performing EC scalar point multiplication, the wNAF point multiplication algorithm was used; which leaked partial information about the nonce used during signature generation. Given an electro-magnetic trace of a few signature generations, the private key could have been computed. This vulnerability affects Firefox < 80 and Firefox for Android < 80. (CVE-2020-6829)
- 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)
Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
