Descriptions

khtml/imload/scaledimageplane.h in Konqueror in KDE 4.7.3 allows remote attackers to cause a denial of service (crash) and possibly read memory via large canvas dimensions, which leads to an unexpected sign extension and a heap-based buffer over-read.

khtml/imload/scaledimageplane.h en Konqueror en KDE v4.7.3, permite a atacantes remotos provocar una denegación de servicio (caída) y posiblemente leer la memoria a través de grandes dimensiones del lienzo, lo que conduce a una extensión de signo inesperado y una sobre lectura de búfer basado en memoria dinámica.

Multiple vulnerabilities have been found in Konqueror, the worst of which may allow execution of arbitrary code. Versions less than 4.9.3-r1 are affected.
