CVE-2015-5279
CVSS v2.0
7.2
Alta
| Vetor | AV:L/AC:L/Au:N/C:C/I:C/A:C |
Name of the Vulnerable Software and Affected Versions
QEMU versions prior to 2.4.0.1
Description
The issue is caused by a heap-based buffer overflow in the
ne2000 receive function. This can allow a local attacker to cause a denial of service or possibly execute arbitrary code via vectors related to receiving packets. A privileged user inside a guest could use this flaw to crash the QEMU instance or potentially execute arbitrary code.Recommendations
For versions prior to 2.4.0.1, update to version 2.4.0.1 or later to resolve the issue. As a temporary workaround, consider disabling the
ne2000 receive function until a patch is available. Restrict access to the vulnerable hw/net/ne2000.c module to minimize the risk of exploitation. Avoid using the NE2000 NIC emulation support in QEMU until the issue is resolved.Exploit
