USN-5435-1: Thunderbird vulnerabilities

Read Time:52 Second

Multiple security issues were discovered in Thunderbird. If a user were
tricked into opening a specially crafted website in a browsing context, an
attacker could potentially exploit these to cause a denial of service,
bypass permission prompts, obtain sensitive information, bypass security
restrictions, cause user confusion, or execute arbitrary code.
(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 Thunderbird would show the wrong security status
after viewing an attached message that is signed or encrypted. An attacker
could potentially exploit this by tricking the user into trusting the
authenticity of a message. (CVE-2022-1520)

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)
