Impact: Processing maliciously crafted web content may lead to
arbitrary code execution. Apple is aware of…
Multiple security issues were discovered in Chromium, which could result
in the execution of arbitrary code, denial of service or information
disclosure.
Multiple vulnerabilities have been discovered in Google Chrome, the most severe of which could allow for arbitrary code execution. Google Chrome is a web browser used to access the internet. 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.

In gcc, a crafted input source file could cause g++ to crash during compilation when provided certain optimization flags. The problem resides in the ipcp_store_vr_results function in gcc/ipa-cp.c.
