Description:
Some vulnerabilities have been reported in FreeType, which can be exploited by malicious people to potentially compromise an application using the library.
1) An integer overflow error within the "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.
2) 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.
3) An integer overflow error within the "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.
Successful exploitation may allow execution of arbitrary code.
The vulnerabilities are reported in version 2.3.9. Other versions may also be affected.
