Cool PDF Reader PDF Stream Handling Buffer Overflow Vulnerability - CVE-2012-4914

evievarga — Wed, 30 Jun 2021 18:23:34 GMT

Today we are getting bombarded with reports of email issues. Digging into the reports we have a lot of users who aren't able to send PDF's and the culprit is that the attachments are getting flagged by PAN.

The related CVE shows it was updated yesterday. I'm struggling to find much information about the CVE. I feel like given the volume of reports we are getting these are false positives but am not sure. Need to do more analysis on my end but am curious if other people are experiencing issues with this?

I opened a case and got an official reply back that yes these are false positive detections.

Thanks for contacting Palo Alto Networks Support. I understand that you believe that you have a potential False Positive case with one of our Vulnerability signatures.

Our engineering team has determined that the signature in question has been exhibiting false positive behavior and they have decided to modify it. The signature will be modified in a future Apps and Threats content release. Since it has been determined that the signature is producing false positive results, you may elect to implement a threat exception. I will let you know once the content version reflecting the change is identified.
