https://notcve.org/view.php?id=CVE-2018-12293
The getImageData function in the ImageBufferCairo class in WebCore/platform/graphics/cairo/ImageBufferCairo.cpp in WebKit, as used in WebKitGTK+ prior to version 2.20.3 and WPE WebKit prior to version 2.20.1, is vulnerable to a heap-based buffer overflow triggered by an integer overflow, which could be abused by crafted HTML content. La función getImageData en la clase ImageBufferCairo en WebCore/platform/graphics/cairo/ImageBufferCairo.cpp en WebKit, tal y como se emplea en WebKitGTK+ en versiones anteriores a la 2.20.3 y WPE WebKit en versiones anteriores a la 2.20.1, es vulnerable a un desbordamiento de búfer basado en memoria dinámica (heap) desencadenado por un desbordamiento de enteros, que podría ser empleado por contenido HTML manipulado. • https://www.exploit-db.com/exploits/45205 http://packetstormsecurity.com/files/148200/WebKitGTK-Data-Leak-Code-Execution.html http://www.openwall.com/lists/oss-security/2018/06/14/1 http://www.securityfocus.com/archive/1/542087/100/0/threaded https://bugs.webkit.org/show_bug.cgi?id=186384 https://security.gentoo.org/glsa/201808-04 https://trac.webkit.org/changeset/232618 https://usn.ubuntu.com/3687-1 • CWE-190: Integer Overflow or Wraparound CWE-787: Out-of-bounds Write •
