ArchLinux: 202003-11: thunderbird: multiple issues
Summary
- CVE-2019-20503 (information disclosure)
An out-of-bounds read has been found in Firefox before 74 and
Thunderbird before 68.6. The inputs to sctp_load_addresses_from_init
are verified by sctp_arethere_unrecognized_parameters; however, the two
functions handled parameter bounds differently, resulting in out of
bounds reads when parameters are partially outside a chunk.
- CVE-2020-6805 (arbitrary code execution)
A use-after-free issue has been found in Firefox before 74 and
Thunderbird before 68.6. When removing data about an origin whose tab
was recently closed, a use-after-free could occur in the Quota manager,
resulting in a potentially exploitable crash.
- CVE-2020-6806 (arbitrary code execution)
A state confusion issue has been found in Firefox before 74 and
Thunderbird before 68.6, in BodyStream::OnInputStreamReady. By
carefully crafting promise resolutions, it was possible to cause an
out-of-bounds read off the end of an array resized during script
execution. This could have led to memory corruption and a potentially
exploitable crash.
- CVE-2020-6807 (arbitrary code execution)
A use-after-free issue has been found in Firefox before 74 and
Thunderbird before 68.6, in cubeb during stream destruction. When a
device was changed while a stream was about to be destroyed, the
stream-reinit task may have been executed after the stream was
destroyed, causing a use-after-free and a potentially exploitable
crash.
- CVE-2020-6811 (arbitrary command execution)
A security issue has been found in Firefox before 74 and Thunderbird
before 68.6, where the 'Copy as cURL' feature of Devtools' network tab
did not properly escape the HTTP method of a request, which can be
controlled by the website. If a user used the 'Copy as Curl' feature
and pasted the command into a terminal, it could have resulted in
command injection and arbitrary command execution.
- CVE-2020-6812 (information disclosure)
An information disclosure issue has been found in Firefox before 74 and
Thunderbird before 68.6. The first time AirPods are connected to an
iPhone, they become named after the user's name by default (e.g. Jane
Doe's AirPods.) Websites with camera or microphone permission are able
to enumerate device names, disclosing the user's name. To resolve this
issue, Firefox added a special case that renames devices containing the
substring 'AirPods' to simply 'AirPods'.
- CVE-2020-6814 (arbitrary code execution)
Several memory safety and script safety bugs have been found in Firefox
before 74, Firefox ESR before 68.6 and Thunderbird before 68.6. Some of
these bugs showed evidence of memory corruption or escalation of
privilege and Mozilla presumes that with enough effort some of these
could have been exploited to run arbitrary code.
Resolution
Upgrade to 68.6.0-1.
# pacman -Syu "thunderbird>=68.6.0-1"
The problems have been fixed upstream in version 68.6.0.
