CVE-2016-10712: Canonical Ubuntu Linux

High severity, CVSS 7.5. EPSS: 2.3% chance of exploitation in the next 30 days.

In PHP before 5.5.32, 5.6.x before 5.6.18, and 7.x before 7.0.3, all of the return values of stream_get_meta_data can be controlled if the input can be controlled (e.g., during file uploads). For example, a "$uri = stream_get_meta_data(fopen($file, "r"))['uri']" call mishandles the case where $file is data:text/plain;uri=eviluri, -- in other words, metadata can be set by an attacker.

Affected products

• Canonical Ubuntu Linux: version 14.04 only; version 16.04 only; version 17.10 only
• PHP PHP: up to and including 5.5.31; from 5.6.0, up to and including 5.6.17; from 7.0.0, up to and including 7.0.2
