CVE-2012-1175

Estado: ModificadaMedia (6.8)—

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.

CVSS

Probabilidad de explotación (EPSS)
