Symantec Encryption Desktop Block Data Move Read Access Violation
Details
Symantec was notified of Symantec Encryption Desktop's improper handling of data when parsing specifically formatted certificates. Attempting to open such a malformed file type could potentially result in memory access violations when the application attempts to parse the file. The identified issues include memory copy and block data move read access violations. Successful exploitation of these memory read access violations would likely result in a possibility of an application crash.
Symantec Response
The certificate file type identified as resulting in the memory read access violations is not a format that is normally used in network communications. Attempted exploitation would only be possible if the malicious individual were able to successfully entice an authorized user to double click and attempt parsing a specifically formatted certificate that had been introduced into the user's environment.
However, to prevent even the low probability of success of this type of issue, Symantec engineers have released an update in Symantec Encryption Desktop 10.3.2 maintenance pack 1 addressing the issue.
Update information
Customers may obtain Symantec Desktop Encryption maintenance updates through their normal Symantec support locations.
