New! Vulnerability Priority Rating (VPR)
Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.

SynopsisThe remote Debian host is missing a security update.
DescriptionSeveral vulnerabilities were found in QEMU, a fast processor emulator :
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).
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.
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.
