The do_dump_data function in utils/opcontrol in OProfile 0.9.6 and earlier might allow local users to create or overwrite arbitrary files via a crafted –session-dir argument in conjunction with a symlink attack on the opd_pipe file, a different vulnerability than CVE-2011-1760.
Weakness
The product attempts to access a file based on the filename, but it does not properly prevent that filename from identifying a link or shortcut that resolves to an unintended resource.

Potential Mitigations
- Follow the principle of least privilege when assigning access rights to entities in a software system.
- Denying access to a file can prevent an attacker from replacing that file with a link to a sensitive file. Ensure good compartmentalization in the system to provide protected areas that can be trusted.
