Name of the Vulnerable Software and Affected Versions: GnuTLS (affected versions not specified)

Description: The issue is related to the GnuTLS implementation of HMAC-SHA-384, which is vulnerable to a Lucky thirteen style attack. This allows remote attackers to conduct distinguishing attacks and plain text recovery attacks via statistical analysis of timing data using crafted packets. The vulnerability is due to errors in the implementation of the cryptographic algorithm, enabling an attacker to exploit it and perform attacks such as plain text recovery.

Recommendations: At the moment, there is no information about a newer version that contains a fix for this vulnerability.
