thunderbird vulnerabilities
Details

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 security restrictions, obtain sensitive information, cause undefined behaviour, spoof the browser UI, or execute arbitrary code. (CVE-2022-22759, CVE-2022-22760, CVE-2022-22761, CVE-2022-22763, CVE-2022-22764, CVE-2022-26381, CVE-2022-26383, CVE-2022-26384)

It was discovered that extensions of a particular type could auto-update themselves and bypass the prompt that requests permissions. If a user were tricked into installing a specially crafted extension, an attacker could potentially exploit this to bypass security restrictions. (CVE-2022-22754)

It was discovered that dragging and dropping an image into a folder could result in it being marked as executable. If a user were tricked into dragging and dropping a specially crafted image, an attacker could potentially exploit this to execute arbitrary code. (CVE-2022-22756)

It was discovered that files downloaded to /tmp were accessible to other users. A local attacker could exploit this to obtain sensitive information. (CVE-2022-26386)

A TOCTOU bug was discovered when verifying addon signatures during install. A local attacker could potentially exploit this to trick a user into installing an addon with an invalid signature. (CVE-2022-26387)

An out-of-bounds write by one byte was discovered when processing messages in some circumstances. If a user were tricked into opening a specially crafted message, an attacker could potentially exploit this to cause a denial of service. (CVE-2022-0566)
