USN-5058-1: Thunderbird vulnerabilities
31 August 2021

Several security issues were fixed in Thunderbird.
Releases

  o Ubuntu 21.04
  o Ubuntu 20.04 LTS
  o Ubuntu 18.04 LTS

Packages

  o thunderbird - Mozilla Open Source mail and newsgroup client

Details

It was discovered that Thunderbird didn't ignore IMAP server responses
prior to completion of the STARTTLS handshake. A person-in-the-middle
could potentially exploit this to trick Thunderbird into showing incorrect
information. ( CVE-2021-29969 )

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, or
execute arbitrary code. ( CVE-2021-29970 , CVE-2021-29976 , CVE-2021-29980 ,
CVE-2021-29984 , CVE-2021-29985 , CVE-2021-29986 , CVE-2021-29988 ,
CVE-2021-29989 , CVE-2021-30547 )

Update instructions

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

Ubuntu 21.04

  o thunderbird - 1:78.13.0+build1-0ubuntu0.21.04.2

Ubuntu 20.04

  o thunderbird - 1:78.13.0+build1-0ubuntu0.20.04.2

Ubuntu 18.04

  o thunderbird - 1:78.13.0+build1-0ubuntu0.18.04.1
