Hi, it's Ryan. Package managers partially automate the process of installing and removing software packages. Most package managers use cryptographic signatures to verify the integrity of packages. In the article Attacks on Package Managers, the authors describe how an attacker can abuse package managers that use digital signatures.
Hi, it's Will. Anybody who has been keeping an eye on the US-CERT Vulnerability Notes has probably noticed that I've published a lot of ActiveX vulnerabilities. So it should be no surprise to learn that we have been testing ActiveX controls and discovering vulnerabilities in the process.
Hi, it's Will again. ActiveX vulnerabilities seem to be getting a lot of attention lately. However, Java applets are also a concern.
The classic understanding of a Java applet is that it runs in a sandbox in your web browser. This model prevents a Java applet from accessing sensitive resources, such as your file system or registry. So, barring vulnerabilities in the Java Virtual Machine (JVM), Java applets should not have the ability to do anything malicious on your system. That was the case with the JDK 1.0 security model.
Hey, it's Will. As you may already be aware, there is active exploitation of a vulnerability in Adobe Flash. So, it's a good idea to make sure that you have the latest version of Flash Player, which, at the time of this writing, is 22.214.171.124. Even if you think that you are up to date, can you be sure?
Hi, Ryan Giobbi from the Vulnerability Analysis team making this post. The CERT/CC has been tracking cross-site scripting vulnerabilities for a long time, and the actual vulnerabilities haven't changed much over the years. However, some technology that was developed to make life easier can actually be exploited to expand the impact of a cross-site scripting attack. Single sign-on is an access-control technology that enables a user to login once and gain access to multiple systems. Some websites use single sign-on to allow access to multiple applications. While this type of authentication is convenient, it has the side effect of introducing an opportunity for an attacker to gain access to multiple systems by targeting a single vulnerable application.
Hi, this is Will Dormann of the CERT/CC Vulnerability Analysis team. A few months ago, reports of infected digital picture frames hit the media. I was curious about how the malicious code was being executed, so I began investigating the Microsoft AutoRun and AutoPlay features.
Hi, this is Art Manion, the Vulnerability Analysis team lead at the CERT Coordination Center (CERT/CC). For our first blog entry, I'd like to briefly explain our efforts to reduce software vulnerabilities.
