CVE-ID : CVE-2021-29969 CVE-2021-29970 CVE-2021-29976 CVE-2021-30547
Package : thunderbird
Type : multiple issues
Remote : Yes
Link : https://security.archlinux.org/AVG-2152
The package thunderbird before version 78.12.0-1 is vulnerable to
multiple issues including arbitrary code execution and content
spoofing.
Upgrade to 78.12.0-1.
The problems have been fixed upstream in version 78.12.0.
None.
If Thunderbird before version 78.12 was configured to use STARTTLS for
an IMAP connection, and an attacker injected IMAP server responses
prior to the completion of the STARTTLS handshake, then Thunderbird
didn’t ignore the injected data. This could have resulted in
Thunderbird showing incorrect information, for example the attacker
could have tricked Thunderbird to show folders that didn’t exist on the
IMAP server.
A malicious webpage could have triggered a use-after-free, memory
corruption, and a potentially exploitable crash. This bug only affected
Firefox before version 90 and Thunderbird before version 78.12 when
accessibility was enabled.
Mozilla developers reported memory safety bugs present in Firefox 89
and Thunderbird 78.11. 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.
An out of bounds write in ANGLE could have allowed an attacker to
corrupt memory leading to a potentially exploitable crash in the
Chromium browser engine before version 91.0.4472.101, Firefox before
version 90 and Thunderbird before version 78.12.
A remote man-in-the-middle attacker could spoof content by injecting
server responses into an IMAP connection that is using STARTTLS.
Furthermore, a remote attacker could execute arbitrary code in a
browsing context using a crafted web page.
