Palo Alto Networks™, the network security company, today announced that its Threat Research Team has discovered three vulnerabilities in today's Microsoft Patch Tuesday security bulletin all of which affect using Microsoft Visio (more). Microsoft credited Palo Alto Networks' Threat Research Team with finding CVE-2011-0092 (Visio Object Memory Corruption Vulnerability) and CVE-2011-0093 (Visio Data Type Memory Corruption Vulnerability), and CVE-2011-0031 (Scripting Engines Information Disclosure Vulnerability).
All three of the following vulnerabilities are categorized as important:
- Visio Object Memory Corruption Vulnerability
A remote code execution vulnerability exists in the way that Microsoft Visio validates objects in memory when parsing specially crafted Visio files. An attacker who successfully exploited this vulnerability could take complete control of an affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. - Visio Data Type Memory Corruption Vulnerability
A remote code execution vulnerability exists in the way that Microsoft Visio parses certain structures when handling specially crafted Visio files. An attacker who successfully exploited this vulnerability could take complete control of an affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. - Scripting Engines Information Disclosure Vulnerability
This information disclosure vulnerability exists in the JScript and VBScript scripting engines due to a memory corruption error. An attacker who successfully exploited this vulnerability could read data not intended to be disclosed.
The Palo Alto Networks Threat Research Team is active in the research community, aggressively pursuing both new vulnerability research and alleviation of all types of threats. The team has leveraged its expertise to uncover a string of critical and important vulnerabilities and have then worked with Microsoft to make sure users are protected.
Enterprises using legacy security technology increasingly lack visibility into and control of application traffic. Palo Alto Networks' next-generation firewalls are unique in the industry in their ability to see and control applications, users and content – not just ports, IP addresses and packets. Palo Alto Networks' next-generation firewalls enable enterprises to create granular, business-relevant security policies and safely control applications instead of the block-or-nothing approach offered by traditional port-blocking firewalls.
About Palo Alto Networks
Palo Alto Networks™ is the network security company. Its next-generation firewalls enable unprecedented visibility and granular policy control of applications and content—by user, not just IP address—at up to 10Gbps with no performance degradation. Based on patent-pending App-ID™ technology, Palo Alto Networks firewalls accurately identify and control applications—regardless of port, protocol, evasive tactic or SSL encryption—and scan content to stop threats and prevent data leakage. Enterprises can for the first time embrace Web 2.0 and maintain complete visibility and control, while significantly reducing total cost of ownership through device consolidation.
