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

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

- Ubuntu 23.04
- 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-2023-4573, CVE-2023-4574,
CVE-2023-4575, CVE-2023-4581, CVE-2023-4584)

It was discovered that Thunderbird did not properly manage memory when
handling WebP images. If a user were tricked into opening a malicious WebP
image file, an attacker could potentially exploit these to cause a denial
of service or execute arbitrary code. (CVE-2023-4863)

Update instructions:

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

Ubuntu 23.04:
  thunderbird                     1:102.15.1+build1-0ubuntu0.23.04.1

Ubuntu 22.04 LTS:
  thunderbird                     1:102.15.1+build1-0ubuntu0.22.04.1

Ubuntu 20.04 LTS:
  thunderbird                     1:102.15.1+build1-0ubuntu0.20.04.1
