CVE-2012-4433 – gegl: Integer overflow, leading to heap-based buffer overflow by parsing PPM image headers

https://notcve.org/view.php?id=CVE-2012-4433

Multiple integer overflows in operations/external/ppm-load.c in GEGL (Generic Graphics Library) 0.2.0 allow remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a large (1) width or (2) height value in a Portable Pixel Map (ppm) image, which triggers a heap-based buffer overflow. Múltiples desbordamientos de enteros en operations/external/ppm-load.c en GEGL (Generic Graphics Library) v0.2.0 permiten a atacantes remotos provocar una denegación de servicio (por caída de la aplicación) o posiblemente ejecutar código de su elección a través de una gran (1) anchura ó (2) altura en una imagen "Mapa de Pixels Portable" (ppm), lo que provoca un desbordamiento de búfer basado en memoria dinámica (heap). • http://git.gnome.org/browse/gegl/commit/?id=1e92e5235ded0415d555aa86066b8e4041ee5a53 http://git.gnome.org/browse/gegl/commit/?id=4757cdf73d3675478d645a3ec8250ba02168a230 http://lists.opensuse.org/opensuse-updates/2013-01/msg00054.html http://rhn.redhat.com/errata/RHSA-2012-1455.html http://secunia.com/advisories/51114 http://secunia.com/advisories/51274 http://www.mandriva.com/security/advisories?name=MDVSA-2013:081 http://www.openwall.com/lists/oss-security/2012/11/06/1 http://www.securityfo • CWE-122: Heap-based Buffer Overflow CWE-189: Numeric Errors •
