Detailsinfo

A vulnerability was found in Mozilla Firefox up to 77.x (Web Browser). It has been declared as problematic. This vulnerability affects some unknown processing of the component RSA Key Generation. The manipulation with an unknown input leads to a risky encryption vulnerability. The CWE definition for the vulnerability is CWE-327. The product uses a broken or risky cryptographic algorithm or protocol. As an impact it is known to affect confidentiality. CVE summarizes:

During RSA key generation, bignum implementations used a variation of the Binary Extended Euclidean Algorithm which entailed significantly input-dependent flow. This allowed an attacker able to perform electromagnetic-based side channel attacks to record traces leading to the recovery of the secret primes. *Note:* An unmodified Firefox browser does not generate RSA keys in normal operation and is not affected, but products built on top of it might. This vulnerability affects Firefox < 78.

The weakness was released 07/09/2020 as Bug 1631597 as not defined bug report (Bugzilla). The advisory is available at bugzilla.mozilla.org. This vulnerability was named CVE-2020-12402 since 04/28/2020. The exploitation appears to be difficult. The attack can be initiated remotely. No form of authentication is required for a successful exploitation. The technical details are unknown and an exploit is not available. This vulnerability is assigned to T1600 by the MITRE ATT&CK project.

Upgrading to version 78.0 eliminates this vulnerability.
