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

  • Onigmo through 6.2.0 has a NULL pointer dereference in onig_error_code_to_str because of fetch_token in regparse.c.(CVE-2019-16161)

  • Onigmo through 6.2.0 has an out-of-bounds read in parse_char_class because of missing codepoint validation in regenc.c.(CVE-2019-16162)

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.
