概要

Microsoft addresses the following vulnerabilities in its May batch of patches:

(MS11-035) Vulnerability in WINS Could Allow Remote Code Execution (2524426)
Risk Rating: Critical

This security update addresses a privately reported vulnerability in the Windows Internet Name Service (WINS). If successfully exploited, this could allow a remote malicious user to execute arbitrary code onto an affected user's system. Since WINS is not pre-installed on any affected operating system by default, only systems manually installed with WINS are affected by this issue. Read more here.

(MS11-036) Vulnerabilities in Microsoft PowerPoint Could Allow Remote Code Execution (2545814)
Risk Rating: Important

This bulletin resolves two privately reported vulnerabilities in Microsoft PowerPoint, which may lead to remote code execution if successfully exploited using a specially crafted PowerPoint file. An attacker could also gain the same user rights as the logged-on user. Users with fewer rights are less impacted compared to those with administrative rights. Installing and configuring Office File Validation (OFV) to prevent the opening of suspicious files can also block attack vectors exploiting these vulnerabilities. Read more here.
