Freshness: upstream tracker timestamp is available; use API updated time as primary recency signal.
CVE-2011-3594 medium priority: Ubuntu including 1 source packages (pidgin), 6 status rows across 6 suites (hardy, lucid, maverick, natty, oneiric, upstream): released 3, ignored 1, needs-triage 1, not-affected 1.
The g_markup_escape_text function in the SILC protocol plug-in in libpurple 2.10.0 and earlier, as used in Pidgin and possibly other products, allows remote attackers to cause a denial of service (crash) via invalid UTF-8 sequences that trigger use of invalid pointers and an out-of-bounds read, related to interactions with certain versions of glib2.
