Security issues were identified and fixed in firefox: layout/generic/nsObjectFrame.cpp in Mozilla Firefox 3.6.7 does not properly free memory in the parameter array of a plugin instance, which allows remote attackers to cause a denial of service or possibly execute arbitrary code via a crafted HTML document, related to the DATA and SRC attributes of an OBJECT element. NOTE: this vulnerability exists because of an incorrect fix for CVE-2010-1214 . Packages for 2008.0 and 2009.0 are provided as of the Extended Maintenance Program. The python packages contained a small dependency problem on 2008.0/2009.0/MES5 that is addressed as well with this advisory.
