MGA6-64 Plasma on HP Probook 6550b.

Installed this, nss (bug 23972) and Thunderbird all at the same time, using QA Repo. US English language versions. No installation issues.

Tested with a newspaper site, Facebook, Youtube, and a weather radar site. All worked as expected, including a loop on the radar site that uses Flash.

OK here for 64-bit. Validating. Advisory in Description.

Actually there's no advisory yet.  Validation is fine but don't push yet.

Oops. Must remember to read these things closer.

Nothing from RedHat yet, but upstream's advisory is posted.

Preliminary advisory for us:

Advisory:
========================

Updated firefox packages fix security vulnerabilities:

A buffer overflow and out-of-bounds read can occur in TextureStorage11 within
the ANGLE graphics library, used for WebGL content. This results in a
potentially exploitable crash (CVE-2018-17466).

A use-after-free vulnerability can occur after deleting a selection element
due to a weak reference to the select element in the options collection. This
results in a potentially exploitable crash (CVE-2018-18492).

A buffer overflow can occur in the Skia library during buffer offset
calculations with hardware accelerated canvas 2D actions due to the use of
32-bit calculations instead of 64-bit. This results in a potentially
exploitable crash (CVE-2018-18493).

A same-origin policy violation allowing the theft of cross-origin URL entries
when using the Javascript location property to cause a redirection to another
site using performance.getEntries(). This is a same-origin policy violation
and could allow for data theft (CVE-2018-19494).

A potential vulnerability leading to an integer overflow can occur during
buffer size calculations for images when a raw value is used instead of the
checked value. This leads to a possible out-of-bounds write (CVE-2018-18498).

Memory safety bugs present in Firefox ESR 60.3, some of which showed evidence
of memory corruption and we presume that with enough effort that some of these
could be exploited to run arbitrary code (CVE-2018-12405).
