Description
Stack-based buffer overflow in libpixman, as used in Pale Moon before 15.4 and possibly other products, has unspecified impact and context-dependent attack vectors. NOTE: this issue might be resultant from an integer overflow in the fast_composite_scaled_bilinear function in pixman-inlines.h, which triggers an infinite loop.
