Description

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.

• CWE-119Improper Restriction of Operations within the Bounds of a Memory BufferThe product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
