Summary
It was discovered that Ghostscript incorrectly handled certain image
files. If a user or automated system were tricked into processing a
specially crafted file, a remote attacker could use this issue to cause
Ghostscript to crash, resulting in a denial of service, or possibly
execute arbitrary code.
