The US-CERT Current Activity web page is a regularly updated summary of the most frequent, high-impact types of security incidents currently being reported to the US-CERT.
Apple has released Security Update 2010-004 and Mac OS X v10.6.4 to address multiple vulnerabilities that affect a number of applications. These vulnerabilities may allow an attacker to execute arbitrary code, cause a denial-of-service condition, operate with elevated privileges, conduct man-in-the-middle attacks, alter configuration settings, or conduct cross-site scripting attacks.
Note that these Apple updates include Adobe Flash Player plugin version 10.0.45.2, which contains vulnerabilities previously identified in Adobe Security Bulletin APSB10-14. The Adobe Product Security Incident Response Team (PSIRT) has published a blog entry recommending that Mac OS X users upgrade to the latest version of the Flash Player (version 10.1.53.64) after applying these Apple updates.
Adobe has released a Security Bulletin to address vulnerabilities in Adobe Flash Player 10.0.45.2 and earlier versions and in Adobe AIR 188.8.131.5230 and earlier versions. Exploitation of these vulnerabilities may allow an attacker to execute arbitrary code or cause a denial-of-service condition.
US-CERT encourages users and administrators to review Adobe Security Bulletin APSB10-14 and to update to Adobe Flash Player 10.1 to help mitigate the risks.
US-CERT is aware of a vulnerability affecting the Mircosoft Windows Help and Support Center. This vulnerability is due to improper sanitization of hcp:// URIs. Exploitation of this vulnerability may allow a remote, unauthenticated attacker to execute arbitrary commands.
US-CERT encourages users and administrators to review Vulnerability Note VU#578319 and implement the workarounds to help mitigate the risks and reduce attack vectors.
