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 logged-in user has administrative privileges, the attacker may be able to fully compromise the affected system. The content also states 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 addressed by this bulletin. General exposure reduction is possible by avoiding untrusted web content and operating without administrative privileges, but no specific vendor mitigation is provided in the supplied material.

Remediation

Patch, then assume compromise.

Apply Microsoft's February 2015 cumulative Internet Explorer security update 3034682 and any required companion updates for the affected platform. The provided content notes that for Internet Explorer 9, 10, and 11, both updates 3021952 and 3034196 were required for full protection, with Microsoft specifying installation-order considerations for manual deployment. Although CVE-2015-0050 specifically affects Internet Explorer 8 and 9, remediation should follow Microsoft's supported cumulative update guidance for the affected product and platform.
