CVE-2017-15118

Qemu: stack buffer overflow in NBD server triggered via long export name

Published Jul 27, 2018 CVSS 3.0 · 8.3 High EPSS 11.9% KEV · Not listed
Description
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.
