According to the version of the gnupg2 package installed, the EulerOS Virtualization for ARM 64 installation on the remote host is affected by the following vulnerability :

  - GnuPG version 2.1.12 - 2.2.11 contains a Cross ite     Request Forgery (CSRF) vulnerability in dirmngr that     can result in Attacker controlled CSRF, Information     Disclosure, DoS. This attack appear to be exploitable     via Victim must perform a WKD request, e.g. enter an     email address in the composer window of     Thunderbird/Enigmail. This vulnerability appears to     have been fixed in after commit     4a4bb874f63741026bd26264c43bb32b1099f060.(CVE-2018-1000     858)

  - Interaction between the sks-keyserver code through 1.2.0 of the SKS keyserver network, and GnuPG through     2.2.16, makes it risky to have a GnuPG keyserver configuration line referring to a host on the SKS     keyserver network. Retrieving data from this network may cause a persistent denial of service, because of     a Certificate Spamming Attack. (CVE-2019-13050)
