It was discovered that the X.org server did not use user privileges when
attempting to open security policy files. Local attackers could exploit
this to probe for files in directories they would not normally be able
to access. (CVE-2007-5958)

It was discovered that the PCF font handling code did not correctly
validate the size of fonts. An authenticated attacker could load a
specially crafted font and gain additional privileges. (CVE-2008-0006)");
