SUSE update for openssl-1_1

1) Covert Timing Channel

EUVDB-ID: #VU103600

Risk: Medium

CVSSv4.0: 1.7 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2024-13176

CWE-ID: CWE-385 - Covert Timing Channel

Exploit availability: No

Description

The vulnerability allows a remote attacker to recover a private key.

The vulnerability exists due to a timing side-channel in ECDSA signature computations. A remote attacker can recover the private key and decrypt data.

Successful exploitation of the vulnerability requires that the attacker's process must either be located in the same physical computer or must have a very fast network connection with low latency.

Mitigation

Update the affected package openssl-1_1 to the latest version.
