Descriptions

The gfxTextRun::SanitizeGlyphRuns function in gfx/thebes/src/gfxFont.cpp in the browser engine in Mozilla Firefox 3.6 before 3.6.2 on Mac OS X, when the Core Text API is used, does not properly perform certain deletions, which allows remote attackers to cause a denial of service (memory corruption and application crash) and possibly execute arbitrary code via an HTML document containing invisible Unicode characters, as demonstrated by the U+FEFF, U+FFF9, U+FFFA, and U+FFFB characters.

La función gfxTextRun::SanitizeGlyphRuns en gfx/thebes/src/gfxFont.cpp en el motor del navegador en Mozilla Firefox v3.6 anterior a v3.6.2 sobre Mac OS X, cuando se utiliza Core Text API, no realiza adecuadamente ciertas supresiones, lo que permite a atacantes remotos producir una denegación de servicio (corrupción de memoria y caída de aplicación) y posiblemente ejecutar código arbitrario a través de un documento HTML que contenga caracteres Unicode invisibles, como se demuestro con los caracteres U+FEFF, U+FFF9, U+FFFA, y U+FFFB
