FKIE_CVE-2016-9104

Vulnerability from fkie_nvd - Published: 2016-12-09 22:59 - Updated: 2026-06-17 00:55
Summary
Multiple integer overflows in the (1) v9fs_xattr_read and (2) v9fs_xattr_write functions in hw/9pfs/9p.c in QEMU (aka Quick Emulator) allow local guest OS administrators to cause a denial of service (QEMU process crash) via a crafted offset, which triggers an out-of-bounds access.
