VirtualBox: unprivileged host user -> host kernel privesc via environment and ioctl (CVE-2017-3561)

This bug report describes two separate issues that, when combined, allow any user on a Linux host system on which VirtualBox is installed to gain code execution in the kernel. Since I'm not sure which one of these issues crosses something you consider to be a privilege boundary, I'm reporting the...

The vulnerability of the Linux operating system, which allows a perpetrator to trigger a service failure or cause other effects

The vulnerability of the sgioctl function in the drivers/scsi/sg.c file of the Linux operating system is caused by buffer overflow on the stack. Exploiting this vulnerability can allow an attacker to trigger a service failure memory spillage or cause other effects by invoking the SGNEXTCMDLEN ioc...

Broadcom: Heap overflow in "wl_iw_get_essid" when handling WLC_GET_SSID ioctl results(CVE-2017-0570)

Broadcom produces Wi-Fi HardMAC SoCs which are used to handle the PHY and MAC layer processing. These chips are present in both mobile devices and Wi-Fi routers, and are capable of handling many Wi-Fi related events without delegating to the host OS. On Android devices, the "bcmdhd" driver is use...
