Descriptions
The bdfReadProperties function in bitmap/bdfread.c in X.Org libXfont before 1.4.9 and 1.5.x before 1.5.1 allows remote authenticated users to cause a denial of service (out-of-bounds write and crash) or possibly execute arbitrary code via a (1) negative or (2) large property count in a BDF font file.
La función bdfReadProperties en bitmap/bdfread.c en X.Org libXfont anterior a 1.4.9 y 1.5.x anterior a 1.5.1 permite a usuarios remotos autenticados causar una denegación de servicio (escritura y caída fuera de rango) o la posibilidad de ejecutar código arbitrario a través de (1) negative o (2) large property count en un archivo de fuente BDF.
An integer overflow flaw was found in the way libXfont processed certain Glyph Bitmap Distribution Format (BDF) fonts. A malicious, local user could use this flaw to crash the X.Org server or, potentially, execute arbitrary code with the privileges of the X.Org server.
