Summary:

Several security issues were fixed in Thunderbird.

cut off in the message header display. An attacker could potentially
exploit this to spoof the sender address. (CVE-2017-7829)

It was discovered that it is possible to execute JavaScript in RSS feeds
in some circumstances. If a user were tricked in to opening a specially
crafted RSS feed, an attacker could potentially exploit this in
combination with another vulnerability, in order to cause unspecified
problems. (CVE-2017-7846)

It was discovered that the RSS feed can leak local path names. If a user
were tricked in to opening a specially crafted RSS feed, an attacker
could potentially exploit this to obtain sensitive information.

a user were tricked in to opening a specially crafted RSS feed, an
attacker could potentially exploit this to cause unspecified problems.
(CVE-2017-7848)

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 cause a denial of service,
execute arbitrary code, or cause other unspecified effects.
