Description
This security bulletin contains information about 3 secuirty vulnerabilities.
1) Heap-based buffer overflow (CVE-ID: CVE-2016-5767)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error in Integer overflow in the gdImageCreate function in gd.c in the GD Graphics Library (aka libgd) before 2.0.34RC1, as used in PHP before 5.5.37, 5.6.x before 5.6.23, and 7.x before 7.0.8,.
