Summary

Multiple buffer overflows in Sun Java Development Kit (JDK) and Java Runtime Environment (JRE) 5.0 Update 7 and earlier, Java System Development Kit (SDK) and JRE 1.4.2_12 and earlier 1.4.x versions, and SDK and JRE 1.3.1_18 and earlier allow attackers to develop Java applets that read, write, or execute local files, possibly related to (1) integer overflows in the Java_sun_awt_image_ImagingLib_convolveBI, awt_parseRaster, and awt_parseColorModel functions; (2) a stack overflow in the Java_sun_awt_image_ImagingLib_lookupByteRaster function; and (3) improper handling of certain negative values in the Java_sun_font_SunLayoutEngine_nativeLayout function. NOTE: some of these details are obtained from third party information.
