Description

USN-3866-2 fixed a regression in Ghostscript. The Ghostscript update introduced a new regression that resulted in certain pages being printed with a blue background. This update fixes the problem.

Original advisory details:

Tavis Ormandy discovered that Ghostscript incorrectly handled certain PostScript files. If a user or automated system were tricked into processing a specially crafted file, a remote attacker could possibly use this issue to access arbitrary files, execute arbitrary code, or cause a denial of service.
