Multiple Vulnerabilities in Google Chrome Could Allow for Arbitrary Code Execution

Read Time:28 Second

Multiple vulnerabilities have been discovered in Google Chrome, the most severe of which could allow for arbitrary code execution. Successful exploitation of the most severe of these vulnerabilities could allow for arbitrary code execution in the context of the logged on user. 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.

NOTE: This update will only fix fresh PostgreSQL installations. Current
PostgreSQL installations will remain vulnerable to this issue until manual
steps are performed. Please see the instructions in the changelog located
at /usr/share/doc/postgresql-*/changelog.Debian.gz after the updated
packages have been installed, or in the PostgreSQL release notes located
