Description
The issue is related to multiple vulnerabilities in the gnutls package, which can lead to a disruption of confidentiality, integrity, and availability of protected information. These vulnerabilities can be exploited remotely. The gnutls recv client kx message function in lib/gnutls kx.c in libgnutls in gnutls-serv in GnuTLS before 2.2.4 continues to process Client Hello messages within a TLS message after one has already been processed, allowing remote attackers to cause a denial of service via a TLS message containing multiple Client Hello messages.

As a temporary workaround, consider disabling the
gnutls recv client kx message function until a patch is available.
Restrict access to the vulnerable gnutls package to minimize the risk of exploitation.
Avoid using the gnutls package until the issue is resolved.
For versions prior to 2.2.5, update to a version that contains the fix for this issue.
