CVE-2010-2805 – freetype: FT_Stream_EnterFrame() does not properly validate certain position values
https://notcve.org/view.php?id=CVE-2010-2805
The FT_Stream_EnterFrame function in base/ftstream.c in FreeType before 2.4.2 does not properly validate certain position values, which allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted font file. La función FT_Stream_EnterFrame en base/ftstream.c de FreeType anterior a v2.4.2 no valida adecuadamente los valores de cierta posición, lo cual permite a atacantes remotos causar una denegación de servicio (fallo de la aplicación) o posiblemente ejecutar código a su elección a través de ficheros de fuentes manipulados. • http://freetype.sourceforge.net/index2.html#release-freetype-2.4.2 http://git.savannah.gnu.org/cgit/freetype/freetype2.git/commit/?id=45a3c76b547511fa9d97aca34b150a0663257375 http://lists.apple.com/archives/security-announce/2010//Nov/msg00000.html http://lists.apple.com/archives/security-announce/2010//Nov/msg00003.html http://marc.info/?l=oss-security&m=128111955616772&w=2 http://secunia.com/advisories/40816 http://secunia.com/advisories/40982 http://secunia.com/advisories/42314 http: • CWE-20: Improper Input Validation •
