Adobe has released Security bulletin APSB07-20 to address multiple vulnerabilities affecting Adobe Flash Player. Attackers could exploit these vulnerabilities to execute arbitrary code, perform DNS rebinding and cross-site scripting attacks, conduct port scans, or cause a denial of service.
Adobe Security Update APSB07-20 addresses a number of vulnerabilities affecting Adobe Flash 22.214.171.124 and earlier, 126.96.36.199 and earlier and 7.0.70 and earlier. Further details are available in the related vulnerability notes.
An attacker could exploit these vulnerabilities by convincing a user to load a specially crafted Flash file. Flash content is widely deployed on the internet. An attacker could distribute Flash files using web sites that allow user-supplied content, like popular social networking sites.
The impacts of these vulnerabilities vary. An attacker may be able to execute arbitrary code, perform DNS rebinding or cross-site scripting attacks, conduct port scans, or cause a denial of service.
