Details

USN-3866-1 fixed vulnerabilities in Ghostscript. The new Ghostscript
version introduced a regression when printing certain page sizes. 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.
