CVE-2017-6507

Microsoft IIS WebDAV ScStoragePathFromUrl Buffer Overflow (CVE-2017-7269)

A buffer overflow exists in Microsoft Internet Information Services 6.0. The vulnerability is due to improper validation of a long header in HTTP request. A remote attacker could exploit this vulnerability by sending a crafted request over a network to the vulnerable application. Successful exploitation could result in denial of service conditions or execute arbitrary code on the target machine.

CVE-2017-7294

The vmw_surface_define_ioctl function in drivers/gpu/drm/vmwgfx/vmwgfx_surface.c in the Linux kernel through 4.10.6 does not validate addition of certain levels data, which allows local users to trigger an integer overflow and out-of-bounds write, and cause a denial of service (system hang or crash) or possibly gain privileges, via a crafted ioctl call for a /dev/dri/renderD* device.
