Responding to Third Party Vulnerabilities

We are now more than one year on from the release of HeartBleed, the first major vulnerability disclosed in widely used third-party code. This is an excellent point in time to look back at what Cisco and our customers have achieved since, including how the Cisco Product Security Incident Response Team (PSIRT) has evolved to meet this new type of threat. It’s also a key time for us to confirm and clarify our commitment to transparency in the vulnerability disclosure process.

In direct response to your feedback, we have also included a Cisco Security Advisory addressing vulnerabilities in Cisco IOS XE Software in this publication. We hope this timeline and additional “bundling” continues to allow your organization to plan and ensure resources are available to analyze, test, and remediate vulnerabilities in your environments.

Talos Discovered Three More Vulnerabilities in Pidgin

This post was authored by Yves Younan and edited by Armin Pelkmann

Table of contents

CVE-2014-3697, VRT-2014-0205
CVE-2014-3696, VRT-2014-0204
CVE-2014-3695, VRT-2014-0203

Cisco Talos is announcing the discovery and patching of another three 3 CVE vulnerabilities in Pidgin (An open-source multi-platform instant messaging client – see wikipedia page). These vulnerabilities were discovered by our team and reported to the Pidgin team. They were found during our initial look at Pidgin which resulted in the first 4 vulnerabilities released in January, but were reported to Pidgin a little later and took longer to get patched. Now that these vulnerabilities were patched in the latest version of Pidgin, 2.10.10, we want to publicly disclose our findings.

 

The first vulnerability (CVE-2014-3697, VRT-2014-0205) is in the routines Pidgin uses to handle smiley and theme packages in Windows. These packages can be downloaded from websites and installed by dragging and dropping them to Pidgin. The packages are TAR files and Pidgin handles them by un-tarring the files to a specific directory. Read More »

Cisco 2014 Midyear Security Report: Focusing on Common Vulnerabilities is Smart Security Strategy

Enterprise security professionals have their hands full these days—monitoring networks for security breaches, managing the implications of “bring your own device” policies, and patching systems to combat “weak links,” or vulnerabilities that could allow online criminals to grant entry.

Regarding this last task, security practitioners may be able to take an approach to addressing vulnerabilities that allows them to more effectively allocate resources toward resolving these challenges. As detailed in the Cisco 2014 Midyear Security Report, urgent critical vulnerabilities—those that merit the time and attention of security executives—make up a very small number of reported vulnerabilities. While all reported vulnerabilities should be patched, it’s wise to focus on those that pose the most danger.

Cisco publishes thousands of multivendor alerts every year, and zero-day vulnerabilities (for which patches are not yet available) tend to win the lion’s share of attention from security practitioners and the media because of their perceived urgency. However, only about two percent of the thousands of reported vulnerabilities were being activity exploited soon after published reports.
