APP: QEMU vnc set_pixel_format bits_per_pixel Null Pointer Dereference
A null pointer dereference vulnerability has been found in QEMU. The vulnerability is due to insufficient checking of an initialized buffer. A remote attacker could exploit this vulnerability by setting bits_per_pixel to a value that is less than 8. Successful exploitation could lead to a denial of service condition on the guest VM.
Extended Description
The set_pixel_format function in ui/vnc.c in QEMU allows remote attackers to cause a denial of service (crash) via a small bytes_per_pixel value.
