A security researcher disclosed a new unpatched bug in Windows that some experts believe could be used to remotely hijack a PC. Microsoft said it is investigating the flaw but provided no information on any analysis it’s conducted thus far. The vulnerability is reportedly in the “BowserWriteErrorLogEntry()” function within the “mrxsmb” driver. A successful exploit could “cause a denial of service or take complete control of a vulnerable system,” Vupen said. Microsoft’s next regularly-scheduled Patch Tuesday is March 8, but it’s unlikely to issue a fix by then.”]
