Уязвимость функции _arc_error_normalized компонента cairo-arc.c библиотеки векторной графики Cairo, позволяющая нарушителю вызвать отказ в обслуживании

cairo 1.16.0, in cairo_ft_apply_variations() in cairo-ft-font.c, would free memory using a free function incompatible with WebKit's fastMalloc, leading to an application crash with a "free(): invalid pointer" error.

An issue was discovered in cairo 1.16.0. There is an assertion problem in the function _cairo_arc_in_direction in the file cairo-arc.c.

An issue was discovered in cairo 1.16.0. There is an infinite loop in the function _arc_error_normalized in the file cairo-arc.c, related to _arc_max_angle_for_tolerance_normalized.

A flaw was found in cairo's image-compositor.c in all versions prior to 1.17.4. This flaw allows an attacker who can provide a crafted input file to cairo's image-compositor (for example, by convincing a user to open a file in an application using cairo, or if an application uses cairo on untrusted input) to cause a stack buffer overflow -> out-of-bounds WRITE. The highest impact from this vulnerability is to confidentiality, integrity, as well as system availability.
