How to fix?

Upgrade Debian:8 php5 to version 5.2.4-1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream php5 package and not the php5 package as distributed by Debian. See How to fix? for Debian:8 relevant fixed versions and status.

The chunk_split function in string.c in PHP 5.2.3 does not properly calculate the needed buffer size due to precision loss when performing integer arithmetic with floating point numbers, which has unknown attack vectors and impact, possibly resulting in a heap-based buffer overflow. NOTE: this is due to an incomplete fix for CVE-2007-2872.
