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

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

- Ubuntu 23.10
- Ubuntu 22.04 LTS
- Ubuntu 20.04 LTS

Summary:

Several security issues were fixed in Thunderbird.

Software Description:
- 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, bypass security restrictions, cross-site
tracing, or execute arbitrary code. (CVE-2024-0743, CVE-2024-2611,
CVE-2024-2614)

Hubert Kario discovered that Thunderbird had a timing side-channel when
performing RSA decryption. A remote attacker could possibly use this
issue to recover sensitive information. (CVE-2023-5388)

Gary Kwong discovered that Thunderbird incorrectly updated return
registers for JIT code on Armv7-A systems. An attacker could potentially
exploit this issue to execute arbitrary code. (CVE-2024-2607)

Ronald Crane discovered that Thunderbird did not properly manage memory
during character encoding. An attacker could potentially exploit this
issue to cause a denial of service. (CVE-2024-2608)

Georg Felber and Marco Squarcina discovered that Thunderbird incorrectly
handled html and body tags. An attacker who was able to inject markup into
a page otherwise protected by a Content Security Policy may have been able
obtain sensitive information. (CVE-2024-2610)

Ronald Crane discovered a use-after-free in Thunderbird when handling code
in SafeRefPtr. An attacker could potentially exploit this issue to cause a
denial of service, or execute arbitrary code. (CVE-2024-2612)

Ryan VanderMeulen and Dan Minor discovered that Thunderbird did not
properly manage memory conditions in ICU. An attacker could potentially
exploit this issue to cause a denial of service. (CVE-2024-2616)

Update instructions:

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

Ubuntu 23.10:
   thunderbird                     1:115.9.0+build1-0ubuntu0.23.10.1

Ubuntu 22.04 LTS:
   thunderbird                     1:115.9.0+build1-0ubuntu0.22.04.1

Ubuntu 20.04 LTS:
   thunderbird                     1:115.9.0+build1-0ubuntu0.20.04.1

In general, a standard system update will make all the necessary changes.
