Package : qemu
Version : 1:2.1+dfsg-12+deb8u10
CVE ID : CVE-2018-12617 CVE-2018-16872 CVE-2019-6778
Debian Bug : 916397, 902725, 921525
Several vulnerabilities were found in QEMU, a fast processor emulator:
CVE-2018-12617
The qmp_guest_file_read function (qga/commands-posix.c) is affected
by an integer overflow and subsequent memory allocation failure. This
weakness might be leveraged by remote attackers to cause denial of
service (application crash).
CVE-2018-16872
The usb_mtp_get_object, usb_mtp_get_partial_object and
usb_mtp_object_readdir functions (hw/usb/dev-mtp.c) are affected by a
symlink attack. Remote attackers might leverage this vulnerability to
perform information disclosure.
CVE-2019-6778
The tcp_emu function (slirp/tcp_subr.c) is affected by a heap buffer
overflow caused by insufficient validation of available space in the
sc_rcv->sb_data buffer. Remote attackers might leverage this flaw to
cause denial of service, or any other unspecified impact.
For Debian 8 "Jessie", these problems have been fixed in version
1:2.1+dfsg-12+deb8u10.
We recommend that you upgrade your qemu packages.
