| Detailed Description |
The Hotfix (MS15-053, 3057263) for 'Vulnerabilities in JScript and VBScript Scripting Engines Could Allow Security Feature Bypass' has not been applied.
This security update resolves ASLR security feature bypasses in the JScript and VBScript scripting engines in Microsoft Windows. An attacker could use one of these ASLR bypasses in conjunction with another vulnerability, such as a remote code execution vulnerability, to more reliably run arbitrary code on a target system.
- VBScript ASLR Bypass(CVE-2015-1684)
A security feature bypass exists when the VBScript engine fails to use the Address Space Layout Randomization (ASLR) security feature, allowing an attacker to more reliably predict the memory offsets of specific instructions in a given call stack. The security feature bypass by itself does not allow arbitrary code execution. However, an attacker could use the ASLR bypass in conjunction with another vulnerability, such as a remote code execution vulnerability, to more reliably run arbitrary code on a target system.
- VBScript and JScript ASLR Bypass(CVE-2015-1686)
A security feature bypass exists when the JScript and VBScript engines fail to use the Address Space Layout Randomization (ASLR) security feature, allowing an attacker to more reliably predict the memory offsets of specific instructions in a given call stack. The security feature bypass by itself does not allow arbitrary code execution. However, an attacker could use the ASLR bypass in conjunction with another vulnerability, such as a remote code execution vulnerability, to more reliably run arbitrary code on a target system.
