CVE-ID : CVE-2021-29967
Package : thunderbird
Type : arbitrary code execution
Remote : Yes
Link : https://security.archlinux.org/AVG-2035
The package thunderbird before version 78.11.0-1 is vulnerable to
arbitrary code execution.
Upgrade to 78.11.0-1.
The problem has been fixed upstream in version 78.11.0.
None.
Mozilla developers reported memory safety bugs present in Firefox 88
and Thunderbird 78.10. 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 could execute arbitrary code using a crafted email
message.
