thunderbird vulnerabilities

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 19.04

- Ubuntu 18.04 LTS
- Ubuntu 16.04 LTS


Several security issues were fixed in Thunderbird.

Software Description:
- thunderbird: Mozilla Open Source mail and newsgroup client


Multiple memory safety issues were discovered in Thunderbird. If a user
were tricked in to opening a specially crafted message, an attacker could
potentially exploit these to cause a denial of service, or execute
arbitrary code.

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

Ubuntu 19.04:
  thunderbird                     1:60.7.1+build1-0ubuntu0.19.04.1

all the necessary changes.
