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 cause a denial of service
via application crash, install lightweight themes without user
interaction, or execute arbitrary code. (CVE-2018-5150, CVE-2018-5154,
CVE-2018-5155, CVE-2018-5159, CVE-2018-5168, CVE-2018-5178)

An issue was discovered when processing message headers in Thunderbird. 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 hang. (CVE-2018-5161)

It was discovered encrypted messages could leak plaintext via the src
attribute of remote images or links. An attacker could potentially exploit
this to obtain sensitive information. (CVE-2018-5162)

It was discovered that the filename of an attachment could be spoofed. An
attacker could potentially exploit this by tricking the user in to opening
an attachment of a different type to the one expected. (CVE-2018-5170)

Multiple security issues were discovered in Skia. If a user were tricked
in to opening a specially crafted message, an attacker could potentially
exploit these to cause a denial of service via application crash, or
execute arbitrary code. (CVE-2018-5183)

It was discovered that S/MIME encrypted messages with remote content could
leak plaintext via a chosen-ciphertext attack. An attacker could
potentially exploit this to obtain sensitive information. (CVE-2018-5184)

It was discovered that plaintext of decrypted emails could leak by
submitting an embedded form. An attacker could potentially exploit this to
obtain sensitive information. (CVE-2018-5185)
