CVE-2024-3296: Red Hat Enterprise Linux 8

Medium severity, CVSS 5.9. EPSS: 0.4% chance of exploitation in the next 30 days.

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. The vulnerability affects the legacy PKCS#1v1.5 RSA encryption padding mode.
