Description
The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.
The ReadSUNImage function in coders/sun.c in GraphicsMagick 1.3.26 has an issue where memory allocation is excessive because it depends only on a length field in a header. This may lead to remote denial of service in the MagickMalloc function in magick/memory.c.
Mitigation
Install update from vendor's website.
