Description

The imagetruecolortopalette function in ext/gd/gd.c in PHP before 5.6.25 and 7.x before 7.0.10 does not properly validate the number of colors, which allows remote attackers to cause a denial of service (select_colors allocation error and out-of-bounds write) or possibly have unspecified other impact via a large value in the third argument.

Affected configurations

• php php 7.0.0 • php php 7.0.1 • php php 7.0.2 • php php 7.0.3 • php php 7.0.4 • php php 7.0.5 • php php 7.0.6 • php php 7.0.7 • php php 7.0.8 • php php 7.0.9 • php php (<= 5.6.24)
