USN-571-1 fixed vulnerabilities in X.org. The upstream fixes were
incomplete, and under certain situations, applications using the MIT-SHM
extension (e.g. Java, wxWidgets) would crash with BadAlloc X errors.
This update fixes the problem.
We apologize for the inconvenience.
Original advisory details:
Multiple overflows were discovered in the XFree86-Misc, XInput-Misc,
TOG-CUP, EVI, and MIT-SHM extensions which did not correctly validate
function arguments. An authenticated attacker could send specially
crafted requests and gain root privileges. (CVE-2007-5760, CVE-2007-6427,
CVE-2007-6428, CVE-2007-6429)
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)
