Article Source Mandriva Linux Security Advisories
Security issues were identified and fixed in firefox 3.5.x:
  The nsObserverList::FillObserverArray function in
  xpcom/ds/nsObserverList.cpp in Mozilla Firefox before 3.5.7 allows
  remote attackers to cause a denial of service (application crash)
  via a crafted web site that triggers memory consumption and an
  accompanying Low Memory alert dialog, and also triggers attempted
  removal of an observer from an empty observers array (CVE-2010-0220).
  Additionally, some packages which require so, have been rebuilt and
  are being provided as updates.
