Description
This security bulletin contains information about 1 security vulnerability.
1) Out-of-bounds read (CVE-ID: CVE-2016-9104)
The vulnerability allows a local privileged user to perform a denial of service (DoS) attack.
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.
