Software Description: – thunderbird: Mozilla Open Source mail and newsgroup client
Multiple security issues were discovered in Thunderbird.

(CVE-2022-29909, CVE-2022-29911, CVE-2022-29912, CVE-2022-29913, CVE-2022-29914, CVE-2022-29916, CVE-2022-29917)

It was discovered that the methods of an Array object could be corrupted as a result of prototype pollution by sending a message to the parent process. If a user were tricked into opening a specially crafted website in a browsing context, an attacker could exploit this to execute JavaScript in a privileged context. (CVE-2022-1529, CVE-2022-1802)
