Package : thunderbird
Type : multiple issues
Remote : Yes
Link : https://security.archlinux.org/AVG-1496
The package thunderbird before version 78.7.0-1 is vulnerable to
multiple issues including arbitrary code execution, information
disclosure and insufficient validation.
Upgrade to 78.7.0-1.
The problems have been fixed upstream in version 78.7.0.
None.
A security issue was found in Thunderbird before version 78.7. During
the plaintext phase of the STARTTLS connection setup, protocol commands
could have been injected and evaluated within the encrypted session.
A security issue was found in Firefox before 84.0. When an HTTPS page
was embedded in an HTTP page, and there was a service worker registered
for the former, the service worker could have intercepted the request
for the secure page despite the iframe not being a secure context due
to the (insecure) framing.
A security issue was found in Firefox before version 85.0 and
Thunderbird before version 78.7. If a user clicked into a specifically
crafted PDF, the PDF reader could be confused into leaking cross-origin
information, when said information is served as chunked data.
A security issue was found in Firefox before version 85.0 and
Thunderbird before version 78.7. Using the new logical assignment
operators in a JavaScript switch statement could have caused a type
confusion, leading to a memory corruption and a potentially exploitable
crash.
A security issue was found in Firefox before version 85.0 and
Thunderbird before version 78.7. Performing garbage collection on re-
declared JavaScript variables resulted in a use-after-poison, and a
potentially exploitable crash.
A security issue was found in Firefox before version 85.0 and
Thunderbird before version 78.7. Mozilla developers reported memory
safety bugs present in Firefox 84 and Firefox ESR 78.6. Some of these
bugs showed evidence of memory corruption and Mozilla presumes that
with enough effort some of these could have been exploited to run
arbitrary code.
A remote attacker might be able to access sensitive information or
execute arbitrary code. In addition, an attacker in position of man-in-
the-middle might be able to inject an IMAP response into a secure
communication channel with the server.
