Oracle · Oracle Solaris · CVE-2011-0412
**Name of the Vulnerable Software and Affected Versions**
Oracle Solaris versions 8, 9, and 10
**Description**
The issue allows local users to obtain password hashes and conduct brute force password guessing attacks due to the storage of back-out patch files (undo.Z) unencrypted with world-readable permissions under /var/sadm/pkg/.
**Recommendations**
For Oracle Solaris versions 8, 9, and 10, consider restricting access to the /var/sadm/pkg/ directory to minimize the risk of exploitation.
As a temporary workaround, restrict read permissions on the undo.Z files to prevent unauthorized access until a more permanent solution is available.
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
