| Vendor description | This security update resolves five privately reported vulnerabilities and one publicly disclosed vulnerability. All of the vulnerabilities could allow remote code execution if a user views a specially crafted Web page using Internet Explorer. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights. |
| SophosLabs comments | Although there are six individual vulnerabilities listed as part of this security bulletin the message is the same for each. Be aware of browsing to untrusted websites. Given the popularity of the affected software it is a possibility that attackers may try to exploit these vulnerabilities although currently we have yet to see any affected web pages. The fact that Microsoft has already issued a patch for these vulnerabilities means that customers already have a source of protection against these attacks available to them and for these reasons SophosLabs has assigned these vulnerabilities a threat level of medium. |
| SophosLabs testing result | N/A |
| Currently known exploits | At the time of writing SophosLabs has seen no samples of malware attempting to exploit this vulnerability. Should this situation change samples will be analysed and the necessary action will be taken. |
