Upstream bug(s):
https://code.google.com/p/chromium/issues/detail?id=567611698 https://code.google.com/p/chromium/issues/detail?id=126887
Statement
Red Hat Product Security rates the severity of this flaw as determined by the Google Chrome Security Advisory.
Mitigation
Operational controls can reduce the likelihood and impact of exploitation:
1. Operational practice: Avoid navigating to untrusted, unknown, or suspicious websites, and do not follow unsolicited web links.
2. Sandboxing enforcement: Ensure Chromium's built-in sandbox protections remain active. Never launch the browser using the `--no-sandbox` command-line flag, as the sandbox restricts attacker code execution to the renderer process and prevents direct access to the underlying host system.
Caveats: These operational controls minimize exposure and contain the blast radius to the sandboxed renderer, but they do not eliminate the vulnerability if a crafted page is rendered.
Understanding the Weakness (CWE)
Confidentiality
Technical Impact: Read Memory
If the expired pointer is used in a read operation, an attacker might be able to control data read in by the application.
Availability
Technical Impact: DoS: Crash, Exit, or Restart
If the expired pointer references a memory location that is not accessible to the product, or points to a location that is "malformed" (such as NULL) or larger than expected by a read or write operation, then a crash may occur.
Integrity,Confidentiality,Availability
Technical Impact: Execute Unauthorized Code or Commands
If the expired pointer is used in a function call, or points to unexpected data in a write operation, then code execution may be possible.
