Gnash Security Vulnerabilities - 2012

CVE-2011-4328

plugin/npapi/plugin.cpp in Gnash before 0.8.10 uses weak permissions (world readable) for cookie files with predictable names in /tmp, which allows local users to obtain sensitive information.

CVE-2012-1175

Integer overflow in the GnashImage::size method in libbase/GnashImage.h in GNU Gnash 0.8.10 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted SWF file, which triggers a heap-based buffer overflow.
