Freshness: upstream tracker timestamp is available; use API updated time as primary recency signal.
CVE-2011-0064 medium priority: Ubuntu including 1 source packages (pango1.0), 6 status rows across 6 suites (dapper, hardy, karmic, lucid, maverick, upstream): released 3, ignored 1, needs-triage 1, not-affected 1.
The hb_buffer_ensure function in hb-buffer.c in HarfBuzz, as used in Pango 1.28.3, Firefox, and other products, does not verify that memory reallocations succeed, which allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) or possibly execute arbitrary code via crafted OpenType font data that triggers use of an incorrect index.
