| Vector | AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H |
Name of the Vulnerable Software and Affected Versions
QEMU version 3.0.0
Description
The issue is related to a heap-based buffer overflow in the
tcp emu function within the slirp/tcp subr.c file of the QEMU emulator. This overflow is associated with the sc rcv->sb data buffer. Exploitation of this issue may allow an attacker to cause a denial of service.Recommendations
For QEMU version 3.0.0, as a temporary workaround, consider disabling the
tcp emu function until a patch is available. Restrict access to the slirp/tcp subr.c module to minimize the risk of exploitation. Avoid using the sc rcv->sb data buffer in the affected TCP/IP emulation until the issue is resolved. At the moment, there is no information about a newer version that contains a fix for this vulnerability.Memory Corruption
