#### **1.0 Introduction** Mozilla Foundation has released security updates to address multiple vulnerabilities in Firefox, Firefox ESR and SeaMonkey. Mozilla encourages users and administrators to review Mozilla's Security Updates and apply the necessary updates.
**2.0 Impact**
The vulnerabilities impacting each software are listed below:
**Firefox**
- **Code execution through incorrect JavaScript bounds checking elimination** - This flaw can be leveraged into the reading and writing of memory allowing for arbitary code execution on the local system.
**Firefox ESR**
- **Reading of local files through manipulation of form autocomplete** – Through this flaw, a user readable file in a known local path could be uploaded to a malicious site. This was done by manipulating the autocomplete feature in a form and user interaction with it.
- **Out-of-bounds read and write while rendering SVG content** - This flaw could potentially allow the attacker to read uninitialized memory.
- **Use-after-free in IndexedDB** - This flaw can lead to a potentially exploitable crash.
**SeaMonkey**
- **Code execution through incorrect JavaScript bounds checking elimination** - This flaw can be leveraged into the reading and writing of memory allowing for arbitary code execution on the local system.
- **Privilege escalation through SVG navigation** - This bypassed the same-origin policy protections by using a flaw in the processing of SVG format content navigation.
**3.0 Affected Products**
The detail lists of the Mozilla products updates are as below:
- Firefox 36.0.3
