| Description: | Summary:
The remote host is missing an update for the Debian 'qemu' package(s) announced via the DLA-1781-1 advisory.
Vulnerability Insight:
Several vulnerabilities were found in QEMU, a fast processor emulator:
CVE-2018-11806
It was found that the SLiRP networking implementation could use a wrong size when reallocating its buffers, which can be exploited by a privileged user on a guest to cause denial of service or possibly arbitrary code execution on the host system.
CVE-2018-18849
It was found that the LSI53C895A SCSI Host Bus Adapter emulation was susceptible to an out of bounds memory access, which could be leveraged by a malicious guest user to crash the QEMU process.
CVE-2018-20815
A heap buffer overflow was found in the load_device_tree function, which could be used by a malicious user to potentially execute arbitrary code with the privileges of the QEMU process.
CVE-2019-9824
William Bowling discovered that the SLiRP networking implementation did not handle some messages properly, which could be triggered to leak memory via crafted messages.
For Debian 8 Jessie, these problems have been fixed in version 1:2.1+dfsg-12+deb8u11.
We recommend that you upgrade your qemu packages.
