According to the versions of the ruby packages installed, the EulerOS Virtualization for ARM 64 installation on the remote host is affected by the following vulnerabilities :
Oniguruma before 6.9.3 allows Stack Exhaustion in regcomp.c because of recursion in regparse.c(CVE-2019-16163)
Oniguruma through 6.9.3, as used in PHP 7.3.x and other products, has a heap-based buffer over-read in str_lower_case_match in regexec.c.(CVE-2019-19246)
An out-of-bounds read vulnerability was found in Oniguruma in the way it handled regular expression quantifiers. A remote attacker could abuse this flaw by providing a malformed regular expression that, when processed by an application linked to Oniguruma, could possibly crash the application, resulting in a denial of service.(CVE-2019-19204)
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.
