| CVE/CAN name | CVE-0209-0220 CVE-0209-0221 CVE-0209-0222 CVE-0209-0223 CVE-0209-0224 CVE-0209-0225 CVE-0209-0226 CVE-0209-0227 CVE-0209-0556 CVE-0209-1128 CVE-0209-1129 CVE-0209-1130 CVE-0209-1131 CVE-0209-1137 |
| Vendor threat level | Critical |
| SophosLabs threat level | Medium |
| Solution | Users are advised to apply the vendor patch for MS09-017 |
| Vendor description | This security update resolves a publicly disclosed vulnerability and several privately reported vulnerabilities in Microsoft Office PowerPoint that could allow remote code execution if a user opens a specially crafted PowerPoint file. An attacker who successfully exploited any of these vulnerabilities could take complete control of an affected system. |
| SophosLabs comments | Although this update patches fourteen individual CVE-categorised vulnerabilities, only one of these has been publicly disclosed (CVE-2009-0556). Over the period of time since receiving the first malware sample that exploited that publicly disclosed vulnerability we have seen only a handful. Given this limited prevalence of exploited PPT documents seen, and also allowing for the fact that this vulnerability is now patched SophosLabs has assigned this vulnerability a medium level threat rating. However it should be noted that although the other vulnerabilities patched as part of this update are not publicly disclosed there is no guarantee that exploits will not be seen for them. Also, it is common to see renewed interest in vulnerabilities after the release of an associated patch. For that reason we advise users to apply MS09-017 at the earliest opportunity. |
