QEMU 'vl.c' Security Bypass Vulnerability
QEMU is prone to a security-bypass vulnerability because the application fails to properly restrict access to certain functionality.
Attackers in a guest system can exploit this issue to bypass certain security restrictions and carry out some unauthorized tasks. This may lead to various attacks.
This issue affects QEMU 0.9.1; other versions may also be vulnerable.
