According to the versions of the perl packages installed, the EulerOS Virtualization for ARM 64 installation on the remote host is affected by the following vulnerabilities :
Integer underflow in regcomp.c in Perl before 5.20, as used in Apple OS X before 10.10.5 and other products, allows context-dependent attackers to execute arbitrary code or cause a denial of service (application crash) via a long digit string associated with an invalid backreference within a regular expression.(CVE-2013-7422)
It was found that perl can load modules from the current directory if not found in the module directories, via the @INC path. A local, authenticated attacker could create a specially crafted module in a writable directory and trick a user into running a perl program from that directory if the module is not found in previous @INC paths, it will load and execute the attacker’s module.(CVE-2016-1238)
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.
