ghostscript vulnerability

A security issue affects these releases of Ubuntu and its derivatives:

• Ubuntu 15.04
• Ubuntu 14.04 LTS
• Ubuntu 12.04 LTS

Summary:

Ghostscript could be made to crash or run programs if it processed a
specially crafted file.

Software Description:

• ghostscript: PostScript and PDF interpreter

Details:

William Robinet and Stefan Cornelius discovered that Ghostscript did not
correctly handle certain Postscript files. If a user or automated system
were tricked into opening a specially crafted file, an attacker could cause
a denial of service or possibly execute arbitrary code.

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 15.04:
libgs9 9.15+dfsg-0ubuntu2.1

Ubuntu 14.04 LTS:
libgs9 9.10~dfsg-0ubuntu10.4

Ubuntu 12.04 LTS:
libgs9 9.05~dfsg-0ubuntu4.3

In general, a standard system update will make all the necessary changes.
