Ubuntu 18.04 LTS / 20.04 LTS : Thunderbird vulnerabilities (USN-5248-1)

critical Nessus Plugin ID 156961

Language:

Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 18.04 LTS / 20.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-5248-1 advisory.

 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-2021-4129, CVE-2021-4140, CVE-2021-29981, CVE-2021-29982, CVE-2021-29987, CVE-2021-29991, CVE-2021-38495, CVE-2021-38496, CVE-2021-38497, CVE-2021-38498, CVE-2021-38500, CVE-2021-38501, CVE-2021-38503, CVE-2021-38504, CVE-2021-38506, CVE-2021-38507, CVE-2021-38508, CVE-2021-38509, CVE-2021-43534, CVE-2021-43535, CVE-2021-43536, CVE-2021-43537, CVE-2021-43538, CVE-2021-43539, CVE-2021-43541, CVE-2021-43542, CVE-2021-43543, CVE-2021-43545, CVE-2021-43656, CVE-2022-22737, CVE-2022-22738, CVE-2022-22739, CVE-2022-22740, CVE-2022-22741, CVE-2022-22742, CVE-2022-22743, 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)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages.
