Details

Multiple security issues were discovered in Thunderbird. If a user were
tricked in to opening a specially crafted website in a browsing context,
an attacker could potentially exploit these to bypass same-origin
restrictions, bypass CSP restrictions, obtain sensitive information, spoof
the origin of modal alerts, cause a denial of service via application
crash, or execute arbitrary code. (CVE-2017-7753, CVE-2017-7779,
CVE-2017-7784, CVE-2017-7785, CVE-2017-7787, CVE-2017-7791, CVE-2017-7792,
CVE-2017-7800, CVE-2017-7801, CVE-2017-7802, CVE-2017-7803, CVE-2017-7807,
CVE-2017-7809)

A buffer overflow was discovered when displaying SVG content in some
circumstances. If a user were tricked in to opening a specially crafted
message, an attacker could potentially exploit this to cause a denial of
service via application crash, or execute arbitrary code. (CVE-2017-7786)
