Details

Multiple security issues were discovered in Thunderbird. If a user were
tricked in to opening a specially crafted website in a browsing-like
context, an attacker could potentially exploit these to read uninitialized
memory, bypass phishing and malware protection, conduct cross-site
scripting (XSS) attacks, cause a denial of service via application crash,
or execute arbitrary code. (CVE-2017-7793, CVE-2017-7810, CVE-2017-7814,
CVE-2017-7818, CVE-2017-7819, CVE-2017-7823, CVE-2017-7824)

Martin Thomson discovered that NSS incorrectly generated handshake hashes.
A remote attacker could potentially exploit this to cause a denial of
service via application crash, or execute arbitrary code. (CVE-2017-7805)
