Ubuntu Security Notice (C) 2005-2016 Canonical, Inc. / NASL script (C) 2006-2016 Tenable Network Security, Inc.
The remote Ubuntu host is missing one or more security-related
Two Denial of Service vulnerabilities have been discovered in the
getimagesize() function. getimagesize() uses format specific internal
functions php_handle_iff() and php_handle_jpeg() which get stuck in
infinite loops when certain (invalid) size parameters are read from
the image. In web applications that allow users to upload arbitrary
image files, a remote attacker could render the server unavailable by
uploading specially crafted images.
Note that Tenable Network Security has extracted the preceding
description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.
Update the affected packages.
