high Nessus Plugin ID 169797

Synopsis

The remote EulerOS Virtualization host is missing multiple security updates.

Description

According to the versions of the gnutls packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

 - A NULL pointer dereference flaw was found in GnuTLS. As Nettle's hash update functions internally call memcpy, providing zero-length input may cause undefined behavior. This flaw leads to a denial of service after authentication in rare circumstances. (CVE-2021-4209)

 - A vulnerability found in gnutls. This security flaw happens because of a double free error occurs during verification of pkcs7 signatures in gnutls_pkcs7_verify function. (CVE-2022-2509)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution
