CVE-2011-0016 medium priority: Ubuntu including 1 source packages (tor), 8 status rows across 8 suites (dapper, hardy, karmic, lucid, maverick, natty, oneiric, upstream): DNE 3, ignored 2, not-affected 2, released 1.
Tor before 0.2.1.29 and 0.2.2.x before 0.2.2.21-alpha does not properly manage key data in memory, which might allow local users to obtain sensitive information by leveraging the ability to read memory that was previously used by a different process.
