This issue was patched in RHSA-2015:1135.

NVD Description

Note: Versions mentioned in the description apply only to the upstream php-snmp package and not the php-snmp package as distributed by RHEL. See How to fix? for RHEL:7 relevant fixed versions and status.

The pcntl_exec implementation in PHP before 5.4.41, 5.5.x before 5.5.25, and 5.6.x before 5.6.9 truncates a pathname upon encountering a \x00 character, which might allow remote attackers to bypass intended extension restrictions and execute files with unexpected names via a crafted first argument. NOTE: this vulnerability exists because of an incomplete fix for CVE-2006-7243.
