high Nessus Plugin ID 142313
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

The remote EulerOS host is missing multiple security updates.

Description

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

- 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)

- regcomp.c in Perl before 5.30.3 allows a buffer overflow via a crafted regular expression because of recursive S_study_chunk calls.(CVE-2020-12723)

- Perl before 5.30.3 on 32-bit platforms allows a heap-based buffer overflow because nested regular expression quantifiers have an integer overflow.(CVE-2020-10543)

- Perl before 5.30.3 has an integer overflow related to mishandling of a 'PL_regkind[OP(n)] == NOTHING' situation. A crafted regular expression could lead to malformed bytecode with a possibility of instruction injection.(CVE-2020-10878)

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.

Solution

Update the affected perl packages.
