Usage of non-constant time base64 decoder could lead to leakage of secret key material

Versions before 0.7.0 of vodozemac use a non-constant time base64 implementation for importing key material for Megolm group sessions and PkDecryption Ed25519 secret keys. This flaw might allow an attacker to infer some information about the secret key material through a side-channel attack. Impa...

The vulnerability of TLS and SSL Mbed TLS implementations lies in the exposure of information due to incompatibilities, allowing attackers to gain access to confidential data.

The vulnerability of TLS and SSL Mbed TLS implementations lies in the use of base64 decoding functions with non-persistent execution time. Exploiting this vulnerability allows a remote attacker to gain access to confidential data...
