ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Successful exploitation can allow remote code execution in the security context of the current user. If the user is running with administrative privileges, the attacker may be able to fully compromise the affected system. The content also states that the vulnerability may cause denial of service through memory corruption.

Mitigation

If you can’t patch tonight, do this now.

No specific workaround or mitigating factor is provided for this specific memory corruption vulnerability in the supplied content. General exposure reduction noted in the bulletin includes the fact that attackers typically must convince a user to browse to malicious content, and Internet Explorer Enhanced Security Configuration on supported Windows Server platforms reduces exposure to specially crafted web content.

Remediation

Patch, then assume compromise.

Apply Microsoft's Internet Explorer security fixes associated with Security Update 3034682. The provided content further states that for Internet Explorer 9, 10, and 11, both update 3021952 and update 3034196 were required for full protection, with Microsoft noting manual installation order requirements and possible automatic installation of related updates on some platforms.
