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, an attacker may be able to take full control of the affected system. The provided description also notes that the vulnerability may be used to cause denial of service through memory corruption.

Mitigation

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

The provided content states that Microsoft identified no mitigating factors and no workarounds for the memory corruption vulnerabilities in this bulletin. On affected Windows Server platforms, Internet Explorer Enhanced Security Configuration reduces exposure to specially crafted web content and therefore lowers risk, but it is not a substitute for patching.

Remediation

Patch, then assume compromise.

Apply Microsoft Security Update 3034682 for affected Internet Explorer versions. For Internet Explorer 9, 10, and 11, the provided content states that both update 3021952 and update 3034196 are required for full protection, and Microsoft noted that 3021952 should be installed before 3034196 when installed manually. Additional related updates, including 3023607 and on some platforms 3036197, may be installed automatically as part of the update process.
