Description:
Secunia Research has discovered a security issue in Adobe Reader for Unix, which can be exploited by malicious, local users to gain knowledge of sensitive information.
The problem is caused due to temporary files being created with permissions based on the user's umask in the "/tmp" folder under certain circumstances when documents are opened.
Successful exploitation allows an unprivileged user to read arbitrary users' documents.
The security issue has been confirmed in version 5.0.10. The vendor has reported that version 5.0.9 is also affected.
Do you have this product installed on your home computer? Scan using the free Personal Software Inspector. Check if a vulnerable version is installed on computers in your corporate network, using the Network Software Inspector.
Solution:
-- Linux and Solaris Platforms --
