VUL-0: CVE-2015-0816: MozillaFirefox,MozillaThunderbird: resource:// documents can load privileged pages (MFSA 2015-33)
Last modified: 2016-04-27 19:37:14 UTC
resource:// documents can load privileged pages
Announced: March 31, 2015
Reporter: Mariusz Mlynski
Products: Firefox, Firefox ESR, Thunderbird
Firefox ESR 31.6
Security researcher Mariusz Mlynski reported, through HP Zero Day Initiative's Pwn2Own contest, that documents loaded though a resource: URL, such as Mozilla's PDF.js PDF file viewer, were able to subsequently load privileged chrome pages. The privilege restrictions on resource: URLs was handled incorrectly and these restrictions could be bypassed if this flaw was combined with a separate vulnerability allowing for same-origin policy violation, it could be used to run arbitrary code.
In general this flaw cannot be exploited through email in the Thunderbird product because scripting is disabled, but is potentially a risk in browser or browser-like contexts.
An update workflow for this issue was started.
This issue was rated as moderate.
Please submit fixed packages until 2015-04-15.
When done, reassign the bug to firstname.lastname@example.org.
