Apple released a security update that repairs 26 vulnerabilities in its OS X operating system and bundled applications.

Of the patched security holes, 17 could expose the user to an arbitrary code execution.

Four of the remaining vulnerabilities could lead to disclosure of confidential information, two could cause an application to crash. A local user in three cases could exploit a flaw to gain additional user rights.

The update repairs four arbitrary code execution vulnerabilities in the way that OS X handles images in the GIF, RAW or Radiance formats. An attacker could exploit those by placing a specially crafted image on a website or send it as an email attachment.

Users can obtain the patch through the software update feature in OS X or download the patch from Apple's website.
