CVE-2011-3464

Estado: ModificadaAlta (7.5)—

Off-by-one error in the png_formatted_warning function in pngerror.c in libpng 1.5.4 through 1.5.7 might allow remote attackers to cause a denial of service (application crash) and possibly execute arbitrary code via unspecified vectors, which trigger a stack-based buffer overflow.
