Resolution ========== Upgrade to 78.10.0-1. # pacman -Syu "thunderbird>=78.10.0-1" The problems have been fixed upstream in version 78.10.0. Workaround ========== None. Description =========== - CVE-2021-23961 (information disclosure) A security issue was found in Firefox before version 85.0. Further techniques that built on the slipstream research combined with a malicious webpage could have exposed both an internal network's hosts as well as services running on the user's local machine. - CVE-2021-23994 (arbitrary code execution) A security issue has been found in Firefox before version 88 and Thunderbird before version 78.10. A WebGL framebuffer was not initialized early enough, resulting in memory corruption and an out of bounds write. - CVE-2021-23995 (arbitrary code execution) A security issue has been found in Firefox before version 88 and Thunderbird before version 78.10. When Responsive Design Mode was enabled, it used references to objects that were previously freed. Mozilla presumes that with enough effort this could have been exploited to run arbitrary code. - CVE-2021-23998 (content spoofing) A security issue has been found in Firefox before version 88 and Thunderbird before version 78.10. Through complicated navigations with new windows, an HTTP page could have inherited a secure lock icon from an HTTPS page. - CVE-2021-23999 (sandbox escape) A security issue has been found in Firefox before version 88 and Thunderbird before version 78.10. If a Blob URL was loaded through some unusual user interaction, it could have been loaded by the System Principal and granted additional privileges that should not be granted to web content. - CVE-2021-24002 (arbitrary command execution) A security issue has been found in Firefox before version 88 and Thunderbird before version 78.10. When a user clicked on an FTP URL containing encoded newline characters (%0A and %0D), the newlines would have been interpreted as such and allowed arbitrary commands to be sent to the FTP server. - CVE-2021-29946 (access restriction bypass) A security issue has been found in Firefox before version 88 and Thunderbird before version 78.10. Ports that were written as an integer overflow above the bounds of a 16-bit integer could have bypassed port blocking restrictions when used in the Alt-Svc header. - CVE-2021-29948 (signature forgery) A security issue has been found in Thunderbird before version 78.10. Signatures are written to disk before and read during verification, which might be subject to a race condition when a malicious local process or user is replacing the file. Impact ====== An attacker is able to execute arbitrary code, spoof context, escape the sandbox, and bypass port blocking restrictions through various means. In addition a local attacker might spoof the verification of emails signed using PGP by winning a race condition.
