Linux Distros Unpatched Vulnerability : CVE-2024-3296

medium Nessus Plugin ID 234207

Language:

Synopsis

The Linux/Unix host has one or more packages installed with a vulnerability that the vendor indicates will not be patched.

Description

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

 - 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. (CVE-2024-3296)

Note that Nessus relies on the presence of the package as reported by the vendor.

Solution

There is no known solution at this time.
