ArchLinux: 201905-9: firefox: multiple issues
Summary
- CVE-2019-7317 (denial of service)
png_image_free in png.c in libpng 1.6.36 has a use-after-free because
png_image_free_function is called under png_safe_execute.
- CVE-2019-9800 (arbitrary code execution)
Several memory safety bugs have been found in Firefox before 67.0 and
Thunderbird before 60.7.0. Some of these bugs showed evidence of memory
corruption and Mozilla presumes that with enough effort some of these
could be exploited to run arbitrary code.
- CVE-2019-9814 (arbitrary code execution)
Several memory safety bugs have been found in Firefox before 67.0. Some
of these bugs showed evidence of memory corruption and Mozilla presumes
that with enough effort some of these could be exploited to run
arbitrary code.
- CVE-2019-9816 (access restriction bypass)
A possible vulnerability exists in Firefox before 67.0 and Thunderbird
before 60.7.0, where type confusion can occur when manipulating
JavaScript objects in object groups, allowing for the bypassing of
security checks within these groups. Note that this vulnerability has
only been demonstrated with UnboxedObjects, which are disabled by
default on all supported releases.
- CVE-2019-9817 (same-origin policy bypass)
In Firefox before 67.0 and Thunderbird before 60.7.0, images from a
different domain can be read using a canvas object in some
circumstances. This could be used to steal image data from a different
site in violation of same-origin policy.
- CVE-2019-9819 (arbitrary code execution)
A vulnerability where a JavaScript compartment mismatch can occur in
Firefox before 67.0 and Thunderbird before 60.7.0, while working with
the fetch API, resulting in a potentially exploitable crash.
- CVE-2019-9820 (arbitrary code execution)
A use-after-free vulnerability can occur in the chrome event handler of
Firefox before 67.0 when it is freed while still in use. This results
in a potentially exploitable crash.
- CVE-2019-9821 (arbitrary code execution)
A use-after-free vulnerability can occur in AssertWorkerThread in
Firefox before 67.0, due to a race condition with shared workers. This
results in a potentially exploitable crash.
- CVE-2019-11691 (arbitrary code execution)
A use-after-free vulnerability can occur in Firefox before 67.0 and
Thunderbird before 60.7.0, when working with XMLHttpRequest (XHR) in an
event loop, causing the XHR main thread to be called after it has been
freed. This results in a potentially exploitable crash.
- CVE-2019-11692 (arbitrary code execution)
A use-after-free vulnerability can occur in Firefox before 67.0 and
Thunderbird before 60.7.0, when listeners are removed from the event
listener manager while still in use, resulting in a potentially
exploitable crash.
- CVE-2019-11693 (arbitrary code execution)
The bufferdata function in WebGL in Firefox before 67.0 and Thunderbird
before 60.7.0 is vulnerable to a buffer overflow with specific graphics
drivers on Linux. This could result in malicious content freezing a tab
or triggering a potentially exploitable crash.
- CVE-2019-11695 (content spoofing)
In Firefox before 67.0, a custom cursor defined by scripting on a site
can position itself over the addressbar to spoof the actual cursor when
it should not be allowed outside of the primary web content area. This
could be used by a malicious site to trick users into clicking on
permission prompts, doorhanger notifications, or other buttons
inadvertently if the location is spoofed over the user interface.
- CVE-2019-11696 (content spoofing)
In Firefox before 67.0, files with the .JNLP extension used for "Java
web start" applications are not treated as executable content for
download prompts even though they can be executed if Java is installed
on the local system. This could allow users to mistakenly launch an
executable binary locally.
- CVE-2019-11697 (access restriction bypass)
In Firefox before 67.0, if the ALT and "a" keys are pressed when users
receive an extension installation prompt, the extension will be
installed without the install prompt delay that keeps the prompt
visible in order for users to accept or decline the installation. A
malicious web page could use this with spoofing on the page to trick
users into installing a malicious extension.
- CVE-2019-11698 (information disclosure)
If a crafted hyperlink is dragged and dropped to the bookmark bar or
sidebar in Firefox before 67.0 or Thunderbird before 60.7.0, and the
resulting bookmark is subsequently dragged and dropped into the web
content area, an arbitrary query of a user's browser history can be run
and transmitted to the content page via drop event data. This allows
for the theft of browser history by a malicious site.
- CVE-2019-11699 (content spoofing)
A malicious page can briefly cause the wrong name to be highlighted as
the domain name in the addressbar during page navigations in Firefox
before 67.0. This could result in user confusion of which site is
currently loaded for spoofing attacks.
- CVE-2019-11701 (cross-site scripting)
The default webcal: protocol handler in Firefox before 67.0 will load a
web site vulnerable to cross-site scripting (XSS) attacks. This default
was left in place as a legacy feature and has now been removed.
Resolution
Upgrade to 67.0-1.
# pacman -Syu "firefox>=67.0-1"
The problems have been fixed upstream in version 67.0.
