APP: Trolltech Qt BMP Handling Overflow

This signature detects attempts to exploit a flaw in the Trolltech Qt image handling subsystem, which is used by the KDE Graphical Environment, commonly found in Linux and other Unix-based systems. A known vulnerability exists in the read_dib function that does not perform proper bounds checking of RLE data from a BMP file. An attacker could exploit this flaw to crash a system or possibly install malicious software when a user attempts to view a specially crafted BMP.

Extended Description

Multiple heap overflows have been reported to exist in the Qt QImage library. These issues may be triggered when handling malformed images of various types, potentially causing a denial of service in applications that use the library to render images. Remote code execution is also possible.
