Freshness: upstream tracker timestamp is available; use API updated time as primary recency signal.
CVE-2011-1155 medium priority: Ubuntu including 1 source packages (logrotate), 7 status rows across 7 suites (dapper, hardy, karmic, lucid, maverick, natty, upstream): released 4, ignored 2, needs-triage 1.
The writeState function in logrotate.c in logrotate 3.7.9 and earlier might allow context-dependent attackers to cause a denial of service (rotation outage) via a (1) \n (newline) or (2) \ (backslash) character in a log filename, as demonstrated by a filename that is automatically constructed on the basis of a hostname or virtual machine name.
