CVE-2007-5633

Estado: ModificadaAlta (7.2)—

Speedfan.sys in Alfredo Milani Comparetti SpeedFan 4.33, when used on Microsoft Windows Vista x64, allows local users to read or write arbitrary MSRs, and gain privileges and load unsigned drivers, via the (1) IOCTL_RDMSR 0x9C402438 and (2) IOCTL_WRMSR 0x9C40243C IOCTLs to \Device\speedfan, as demonstrated by an IOCTL_WRMSR action on MSR_LSTAR.
