Buffer Overflow

QEMU is vulnerable to buffer overflows. A remote, unauthenticated attacker could cause a system crash due to device tree size manipulation before buffer allocation leading to denial of service conditions. Affected by this issue is the function loadimage of the file devicetree.c...

QEMU: device_tree: heap buffer overflow while loading device tree blob

A heap buffer overflow issue was found in the loaddevicetree function of QEMU, which is invoked to load a device tree blob at boot time. It occurs due to device tree size manipulation before buffer allocation, which could overflow a signed int type. A user/process could use this flaw to potential...

The vulnerability of the `load_device_tree` function in the QEMU hardware emulation software allows a hacker to execute arbitrary code.

The vulnerability of the loaddevicetree function in the QEMU hardware emulation software is related to buffer overflow in dynamic memory. Exploiting this vulnerability can allow an attacker to execute arbitrary code...
