Multiple integer overflows in FreeType might allow for the remote execution of arbitrary code or a Denial of Service.
FreeType is a high-quality and portable font engine.
Tavis Ormandy reported multiple integer overflows in the cff_charset_compute_cids() function in cff/cffload.c, sfnt/tccmap.c and the ft_smooth_render_generic() function in smooth/ftsmooth.c, possibly leading to heap or stack-based buffer overflows.
A remote attacker could entice a user or automated system to open a specially crafted font file, possibly resulting in the execution of arbitrary code with the privileges of the user running the application, or a Denial of Service.
There is no known workaround at this time.
All FreeType users should upgrade to the latest version:
