NVD Description

Note: Versions mentioned in the description apply only to the upstream qtwebengine-opensource-src package and not the qtwebengine-opensource-src package as distributed by Ubuntu.

A heap-based buffer overflow was found in openjpeg in color.c:379:42 in sycc420_to_rgb when decompressing a crafted .j2k file. An attacker could use this to execute arbitrary code with the permissions of the application compiled against openjpeg.
