According to the versions of the bind packages installed, the EulerOS Virtualization for ARM 64 installation on the remote host is affected by the following vulnerabilities :
A denial of service flaw was discovered in bind versions that include the ‘deny-answer-aliases’ feature. This flaw may allow a remote attacker to trigger an INSIST assert in named leading to termination of the process and a denial of service condition.(CVE-2018-5740)
A use-after-free flaw leading to denial of service was found in the way BIND internally handled cleanup operations on upstream recursion fetch contexts. A remote attacker could potentially use this flaw to make named, acting as a DNSSEC validating resolver, exit unexpectedly with an assertion failure via a specially crafted DNS request.(CVE-2017-3145)
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.
