EulerOS Virtualization 3.0.2.2 : perl (EulerOS-SA-2021-2157)

high Nessus Plugin ID 151395

Synopsis

The remote EulerOS Virtualization host is missing multiple security updates.

Description

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

- Perl might allow context-dependent attackers to bypass the taint protection mechanism in a child process via duplicate environment variables in envp.(CVE-2016-2381)

- 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)

- 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)

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.
