Descriptions

FontForge 20161012 is vulnerable to a buffer over-read in getsid (parsettf.c) resulting in DoS or code execution via a crafted otf file.

FontForge versión 20161012, es vulnerable a una lectura excesiva del búfer en la función getsid (parsettf.c) resultando en una DoS o ejecución de código por medio de un archivo otf creado.

It was discovered that FontForge, a font editor, did not correctly validate its input. An attacker could use this flaw by tricking a user into opening a maliciously crafted OpenType font file, thus causing a denial-of-service via application crash, or execution of arbitrary code. For the oldstable distribution (jessie), these problems have been fixed in version 20120731.b-5+deb8u1. For the stable distribution (stretch), these problems have been fixed in version 1:20161005~dfsg-4+deb9u1.
