CVE-2011-0492 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 allows remote attackers to cause a denial of service (assertion failure and daemon exit) via blobs that trigger a certain file size, as demonstrated by the cached-descriptors.new file.
