RHEL 8 : php:7.4 (RHSA-2022:6542)

high Nessus Plugin ID 165187

Synopsis

The remote Red Hat host is missing one or more security updates for php:7.4.

Description

The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2022:6542 advisory.

PHP is an HTML-embedded scripting language commonly used with the Apache HTTP Server.

Security Fix(es):

* Archive_Tar: allows an unserialization attack because phar: is blocked but PHAR: is not blocked (CVE-2020-28948)

* Archive_Tar: improper filename sanitization leads to file overwrites (CVE-2020-28949)

* Archive_Tar: directory traversal due to inadequate checking of symbolic links (CVE-2020-36193)

For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the RHEL php:7.4 package based on the guidance in RHSA-2022:6542.
