CVE-2012-4513

Status Candidate

Overview

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.

Red Hat Security Advisory 2012-1416-01 - The kdelibs packages provide libraries for the K Desktop Environment. Konqueror is a web browser. A heap-based buffer overflow flaw was found in the way the CSS parser in kdelibs parsed the location of the source for font faces. A web page containing malicious content could cause an application using kdelibs to crash or, potentially, execute arbitrary code with the privileges of the user running the application. A heap-based buffer over-read flaw was found in the way kdelibs calculated canvas dimensions for large images. A web page containing malicious content could cause an application using kdelibs to crash or disclose portions of its memory.
