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.

- 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)

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.
