Description
===========

- CVE-2018-18335 (arbitrary code execution)

A heap-based buffer overflow has been found in the Skia component of
chromium before 71.0.3578.80 and thunderbird before 60.5.1.

- CVE-2018-18356 (arbitrary code execution)

A use-after-free has been found in the Skia component of chromium
before 71.0.3578.80 and firefox before 65.0.1 and thunderbird before
60.5.1.

- CVE-2018-18509 (insufficient validation)

A flaw during verification of certain S/MIME signatures causes emails
to be shown in Thunderbird before 60.5.1 as having a valid digital
signature, even if the shown message contents aren't covered by the
signature. The flaw allows an attacker to reuse a valid S/MIME
signature to craft an email message with arbitrary content.

An integer overflow issue has been found in the Skia component of
firefox before 65.0.1 and thunderbird before 60.5.1.

A remote attacker can reuse a valid S/MIME signature to craft an e-mail
message with arbitrary content, and execute arbitrary code through
skia.
