Security Bulletin
This security bulletin contains one low risk vulnerability.
EUVDB-ID: #VU14116
Risk: Low
CVSSv3.1: 6.7 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:P/RL:O/RC:C]
CVE-ID: CVE-2018-12617
CWE-ID:
CWE-190 - Integer overflow
Exploit availability: Yes
DescriptionThe vulnerability allows a remote attacker to cause DoS condition on the target system.
The vulnerability exists due to integer overflow in qmp_guest_file_read in qga/commands-posix.c and qga/commands-win32.c in qemu-ga (aka QEMU Guest Agent). A remote attacker can send a specially crafted QMP command (including guest-file-read with a large count value) to the agent via the listening socket, cause a g_malloc0() call to trigger a segmentation fault when trying to allocate a large memory chunk and cause the service to crash.
MitigationUpdate the affected packages.
Opensuse: 15.0
