Symantec LiveUpdate for Macintosh Local Privilege Escalation

Some components of Symantec's LiveUpdate for Macintosh do not set their execution path environment

Risk Impact
Medium

A non-privileged user can change their execution path environment. If the user then executes one of these components, it will inherit the changed environment and use it to locate system commands. These components are configured to run with System Administrative privileges (SUID) and are vulnerable to a potential Trojan horse attack.

Symantec Response
A patch has been created and made available for all affected versions of the product through Symantec LiveUpdate.

To perform a manual update using Symantec LiveUpdate, users should:

• Open any installed Symantec product
• Click on LiveUpdate in the toolbar
• Run LiveUpdate until all available Symantec product updates are downloaded and installed

Symantec is not aware of any active attempts against or customers impacted by this issue.

As a part of normal best practices, users should keep vendor-supplied patches for all application software and operating systems up-to-date. Symantec strongly recommends any affected customers update their product immediately to protect against these types of threats.
