USN-5248-1: Thunderbird vulnerabilities

Releases

• Ubuntu 20.04 LTS
• Ubuntu 18.04 ESM

Packages

• thunderbird - Mozilla Open Source mail and newsgroup client

Details

Multiple security issues were discovered in Thunderbird. If a user were
tricked into opening a specially crafted website in a browsing context, an
attacker could potentially exploit these to cause a denial of service,
obtain sensitive information, trick a user into accepting unwanted
permissions, conduct header splitting attacks, conduct spoofing attacks,
bypass security restrictions, confuse the user, or execute arbitrary code.

CVE-2022-22745, CVE-2022-22747, CVE-2022-22748, CVE-2022-22751)

It was discovered that Thunderbird ignored the configuration to require
STARTTLS for an SMTP connection. A person-in-the-middle could potentially
exploit this to perform a downgrade attack in order to intercept messages
or take control of a session. (CVE-2021-38502)

It was discovered that JavaScript was unexpectedly enabled in the
composition area. An attacker could potentially exploit this in
combination with another vulnerability, with unspecified impacts.
(CVE-2021-43528)

A buffer overflow was discovered in the Matrix chat library bundled with
Thunderbird. An attacker could potentially exploit this to cause a denial
of service, or execute arbitrary code. (CVE-2021-44538)

It was discovered that Thunderbird's OpenPGP integration only considered
the inner signed message when checking signature validity in a message
that contains an additional outer MIME layer. An attacker could
potentially exploit this to trick the user into thinking that a message
has a valid signature. (CVE-2021-4126)

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 20.04

• thunderbird - 1:91.5.0+build1-0ubuntu0.20.04.1

Ubuntu 18.04

• thunderbird - 1:91.5.0+build1-0ubuntu0.18.04.1

After a standard system update you need to restart Thunderbird to make
all the necessary changes.
