A vulnerability has been discovered in ChromeOS which could allow for arbitrary code execution. ChromeOS is a Linux-based operating system developed and designed by Google. Depending on the privileges associated with the user an attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Users whose accounts are configured to have fewer user rights on the system could be less impacted than those who operate with administrative user rights.

Multiple vulnerabilities have been discovered in Mozilla products, the most severe of which could allow for arbitrary code execution.
Mozilla Firefox is a web browser used to access the Internet.
Mozilla Firefox ESR is a version of the web browser intended to be deployed in large organizations.
Mozilla Thunderbird is an email client.
Successful exploitation of the most severe of these vulnerabilities could allow for arbitrary code execution. Depending on the privileges associated with the user an attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Users whose accounts are configured to have fewer user rights on the system could be less impacted than those who operate with administrative user rights.
Tony Battersby discovered that OpenSSL incorrectly handled key and
initialization vector (IV) lengths. This could lead to truncation issues
and result in loss of confidentiality for some symmetric cipher modes.
(CVE-2023-5363)
Juerg Wullschleger discovered that OpenSSL incorrectly handled the AES-SIV
cipher. This could lead to empty data entries being ignored, resulting in
certain applications being misled. This issue only affected Ubuntu 22.04
LTS and Ubuntu 23.04. (CVE-2023-2975)
It was discovered that OpenSSL incorrectly handled checking excessively
long DH keys or parameters. A remote attacker could possibly use this issue
