Summary
Red Hat Security Advisory: php-pear security update

Notes

Topic
An update for php-pear is now available for Red Hat Enterprise Linux 7. Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.
Details
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.
