Freshness: upstream tracker timestamp is available; use API updated time as primary recency signal.
CVE-2011-4601 low priority: Ubuntu including 1 source packages (pidgin), 7 status rows across 7 suites (hardy, lucid, maverick, natty, oneiric, precise, upstream): released 3, ignored 2, needs-triage 1, not-affected 1.
family_feedbag.c in the oscar protocol plugin in libpurple in Pidgin before 2.10.1 does not perform the expected UTF-8 validation on message data, which allows remote attackers to cause a denial of service (application crash) via a crafted (1) AIM or (2) ICQ message associated with buddy-list addition.
