firefox vulnerabilities
==========================================================================

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

- Ubuntu 20.04 LTS

Summary:

Several security issues were fixed in Firefox.

Software Description:
- firefox: Mozilla Open Source web browser

Details:

Multiple security issues were discovered in Firefox. If a user were
tricked into opening a specially crafted website, an attacker could
potentially exploit these to cause a denial of service, obtain sensitive
information across domains, or execute arbitrary code. (CVE-2023-5169,
CVE-2023-5170, CVE-2023-5171, CVE-2023-5172, CVE-2023-5175, CVE-2023-5176)

Ronald Crane discovered that Firefox did not properly manage memory when
non-HTTPS Alternate Services (network.http.altsvc.oe) is enabled. An
attacker could potentially exploit this issue to cause a denial of service.
(CVE-2023-5173)

Clément Lecigne discovered that Firefox did not properly manage memory when
handling VP8 media stream. An attacker-controlled VP8 media stream could
lead to a heap buffer overflow in the content process, resulting in a
denial of service, or possibly execute arbitrary code. (CVE-2023-5217)

Update instructions:

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

Ubuntu 20.04 LTS:
  firefox                         118.0.1+build1-0ubuntu0.20.04.1

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