libXfont2: BitmapScaleBitmaps Integer Overflow Heap Buffer Overflow

A flaw was found in libXfont2. In the BitmapScaleBitmaps function, an integer overflow can occur when calculating the memory needed for font glyphs. This overflow leads to a heap buffer overflow, where a smaller-than-required memory buffer is allocated. A local attacker can exploit this by loadin...
