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
