The package firefox before version 50.1.0-1 is vulnerable to multiple
issues including arbitrary code execution, access restriction bypass,
information disclosure, content spoofing, cross-site scripting and
Upgrade to 50.1.0-1.
# pacman -Syu "firefox>=50.1.0-1"
The problems have been fixed upstream in version 50.1.0.
- CVE-2016-9080 (arbitrary code execution)
Mozilla developers and community members Kan-Ru Chen, Christian Holler,
and Tyson Smith reported memory safety bugs present in Firefox 50.0.2.
Some of these bugs showed evidence of memory corruption and we presume
that with enough effort that some of these could be exploited to run
- CVE-2016-9893 (arbitrary code execution)
Mozilla developers and community members Jan de Mooij, Iris Hsiao,
Christian Holler, Carsten Book, Timothy Nikkel, Christoph Diehl, Olli
Pettay, Raymond Forbes, and Boris Zbarsky reported memory safety bugs
present in Firefox 50.0.2 and Firefox ESR 45.5.1. Some of these bugs
showed evidence of memory corruption and we presume that with enough
effort that some of these could be exploited to run arbitrary code.
- CVE-2016-9894 (arbitrary code execution)
A buffer overflow in SkiaGl caused when a GrGLBuffer is truncated
during allocation. Later writers will overflow the buffer, resulting in
a potentially exploitable crash.
- CVE-2016-9895 (access restriction bypass)
Event handlers on marquee elements were executed despite a strict
- CVE-2016-9896 (arbitrary code execution)
Use-after-free while manipulating the navigator object within WebVR.
Note: WebVR is not currently enabled by default.
- CVE-2016-9897 (arbitrary code execution)
Memory corruption resulting in a potentially exploitable crash during
WebGL functions using a vector constructor with a varying array within
- CVE-2016-9898 (arbitrary code execution)
Use-after-free resulting in potentially exploitable crash when
manipulating DOM subtrees in the Editor.
- CVE-2016-9899 (arbitrary code execution)
Use-after-free while manipulating DOM events and removing audio
elements due to errors in the handling of node adoption.
- CVE-2016-9900 (information disclosure)
External resources that should be blocked when loaded by SVG images can
bypass security restrictions through the use of data: URLs. This could
allow for cross-domain data leakage.
- CVE-2016-9901 (insufficient validation)
HTML tags received from the Pocket server will be processed without
about:pocket-saved (unprivileged) page, giving it access to Pocket's
messaging API through HTML injection.
- CVE-2016-9902 (content spoofing)
The Pocket toolbar button, once activated, listens for events fired
from it's own pages but does not verify the origin of incoming events.
This allows content from other origins to fire events and inject
content and commands into the Pocket context.
Note: this issue does not affect users with e10s enabled.
- CVE-2016-9903 (cross-site scripting)
Mozilla's add-ons SDK had a world-accessible resource with an HTML
injection vulnerability. If an additional vulnerability allowed this
resource to be loaded as a document it could allow injecting content
and script into an add-on's context.
- CVE-2016-9904 (information disclosure)
whether an atom is used by another compartment/zone in specific
contexts. This could be used to leak information, such as usernames
A remote attacker can access sensitive information, bypass security
measures and execute arbitrary code on the affected host.
