CVE-2017-15118
Last modified
CVE-2017-15118 is a high-severity vulnerability rated 8.3/10 on the CVSS scale. A stack-based buffer overflow vulnerability was found in NBD server implementation in qemu before 2.11 allowing a client to request an export name of size up to 4096 bytes, which in fact should be limited to 256 bytes, causing an out-of-bounds stack write in the qemu process. If NBD server requires TLS, the attacker cannot trigger the buffer overflow without first successfully negotiating TLS.. EPSS estimates a 11.93% chance of exploitation in the next 30 days.
