Synopsis

Description

According to the versions of the gnutls packages installed, the EulerOS 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)
