Synopsis

The remote Red Hat host is missing one or more security updates for php-pear.

Description

The remote Redhat Enterprise Linux 7 host has a package installed that is affected by multiple vulnerabilities as referenced in the RHSA-2022:7340 advisory.

The php-pear package contains the PHP Extension and Application Repository (PEAR), a framework and distribution system for reusable PHP components.

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.
