GHSA-g45g-prg5-m635 PUBLISHED CVSS 9.800000190734863 CRITICAL

Record from GitHub Advisory Database · Published May 13, 2022

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.
