## 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.
