Description

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. The Red Hat Enterprise Linux remains unaffected by this vulnerability since it does not include the vulnerable codebase or version.

Red Hat severity: Moderate — CVSS 5.9 (CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N). Weakness: CWE-208.

Red Hat lists Red Hat Enterprise Linux 8; Red Hat Enterprise Linux 9 as not affected.
