Secunia reports :

Some vulnerabilities have been reported in FreeType, which can be exploited by malicious people to potentially compromise an application using the library.

An integer overflow error within the β€˜cff_charset_compute_cids()’ function in cff/cffload.c can be exploited to potentially cause a heap-based buffer overflow via a specially crafted font.

Multiple integer overflow errors within validation functions in sfnt/ttcmap.c can be exploited to bypass length validations and potentially cause buffer overflows via specially crafted fonts.

An integer overflow error within the β€˜ft_smooth_render_generic()’ function in smooth/ftsmooth.c can be exploited to potentially cause a heap-based buffer overflow via a specially crafted font.
