Ubuntu Security Notice USN-4328-1
April 13, 2020

thunderbird vulnerabilities
==========================================================================

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

- Ubuntu 19.10
- Ubuntu 18.04 LTS

Summary:

Several security issues were fixed in Thunderbird.

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

Details:

It was discovered that Message ID calculation was based on uninitialized
data. An attacker could potentially exploit this to obtain sensitive
information. (CVE-2020-6792)

Mutiple security 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, obtain sensitive
information, or execute arbitrary code. (CVE-2020-6793, CVE-2020-6795,
CVE-2020-6822)

It was discovered that if a user saved passwords before Thunderbird 60
and then later set a master password, an unencrypted copy of these
passwords would still be accessible. A local user could exploit this to
obtain sensitive information. (CVE-2020-6794)

Multiple security issues were discovered in Thunderbird. If a user were
tricked in to opening a specially crafted website in a browsing context,
an attacker could potentially exploit these to cause a denial of service,
conduct cross-site scripting (XSS) attacks, obtain sensitive information,
or execute arbitrary code. (CVE-2019-20503, CVE-2020-6798, CVE-2020-6800,
CVE-2020-6805, CVE-2020-6806, CVE-2020-6807, CVE-2020-6812, CVE-2020-6814,
CVE-2020-6819, CVE-2020-6820, CVE-2020-6821, CVE-2020-6825)

It was discovered that the Devtools’ ‘Copy as cURL’ feature did not
fully escape website-controlled data. If a user were tricked in to using
the ‘Copy as cURL’ feature to copy and paste a command with specially
crafted data in to a terminal, an attacker could potentially exploit this
to execute arbitrary commands via command injection. (CVE-2020-6811)

Update instructions:

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

Ubuntu 19.10:
thunderbird 1:68.7.0+build1-0ubuntu0.19.10.1

Ubuntu 18.04 LTS:
thunderbird 1:68.7.0+build1-0ubuntu0.18.04.1

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