EulerOS Virtualization for ARM 64 : perl (EulerOS-SA-2019-2326)

critical Nessus Plugin ID 131491


The remote EulerOS Virtualization for ARM 64 host is missing multiple security updates.


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 :

- An issue was discovered in Perl 5.18 through 5.26. A crafted regular expression can cause a heap-based buffer overflow, with control over the bytes written.(CVE-2018-6797)

- An issue was discovered in Perl 5.22 through 5.26.
Matching a crafted locale dependent regular expression can cause a heap-based buffer over-read and potentially information disclosure.(CVE-2018-6798)

- Heap-based buffer overflow in the pack function in Perl before 5.26.2 allows context-dependent attackers to execute arbitrary code via a large item count.(CVE-2018-6913)

- Perl before 5.26.3 and 5.28.0 before 5.28.1 has a buffer overflow via a crafted regular expression that triggers invalid write operations.(CVE-2018-18312)

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.


Update the affected perl packages.
