CVE-2023-49092 Open this link in a new tabHow to fix?
There is no fixed version for rsa.
Overview
Affected versions of this package are vulnerable to Observable Timing Discrepancy. Due to a non-constant-time implementation, information about the private key is leaked through timing information which is observable over the network. An attacker may be able to use that information to recover the key (Marvin).
Workaround
This vulnerability can be mitigated by avoiding using the rsa crate in settings where attackers are able to observe timing information.
