According to the versions of the perl packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :
Perl before 5.26.3 and 5.28.x before 5.28.1 has a buffer overflow via a crafted regular expression that triggers invalid write operations.(CVE-2018-18311)
It was found that the Archive::Tar module did not properly sanitize symbolic links when extracting tar archives. An attacker, able to provide a specially crafted archive for processing, could use this flaw to write or overwrite arbitrary files in the context of the Perl interpreter.(CVE-2018-12015)
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.
