Red Hat: RHSA-2017:3221-01 Moderate: PHP Denial of Service Risk

Calendar Grey November 15, 2017
Scroller Redhat
Red Hat unveiled a significant security patch for php, targeting vulnerabilities that could lead to service interruptions and enhancing overall robustness.
An update for php is now available for Red Hat Enterprise Linux 7

Solution

For details on how to apply this update, which includes the changes described in this advisory, refer to:

https://access.redhat.com/articles/11258

After installing the updated packages, the httpd daemon must be restarted for the update to take effect.

Summary

PHP is an HTML-embedded scripting language commonly used with the Apache HTTP Server.
Security Fix(es):
* A null pointer dereference flaw was found in libgd. An attacker could use a specially-crafted .gd2 file to cause an application linked with libgd to crash, leading to denial of service. (CVE-2016-10167)
* An integer overflow flaw, leading to a heap-based buffer overflow was found in the way libgd read some specially-crafted gd2 files. A remote attacker could use this flaw to crash an application compiled with libgd or in certain cases execute arbitrary code with the privileges of the user running that application. (CVE-2016-10168)
