Last modified

CVE-2024-3296 is a medium-severity vulnerability rated 5.9/10 on the CVSS scale. A timing-based side-channel flaw exists in the rust-openssl package, which could be sufficient to recover a plaintext across a network in a Bleichenbacher-style attack. To achieve successful decryption, an attacker would have to be able to send a large number of trial messages for decryption. EPSS estimates a 0.41% chance of exploitation in the next 30 days.

Description
