Heap-based buffer overflow in Cirrus CLGD 54xx VGA Emulator in Quick Emulator (Qemu) 2.8 and earlier allows local guest OS users to execute arbitrary code or cause a denial of service (crash) via vectors related to a VNC client updating its display after a VGA operation.
CVE-2017-8309 3 Debian, Qemu, Redhat 3 Debian Linux, Qemu, Openstack 2021-08-04 7.8 HIGH 7.5 HIGH
Memory leak in the audio/audio.c in QEMU (aka Quick Emulator) allows remote attackers to cause a denial of service (memory consumption) by repeatedly starting and stopping audio capture.
CVE-2017-8379 3 Debian, Qemu, Redhat 3 Debian Linux, Qemu, Openstack 2021-08-04 4.9 MEDIUM 6.5 MEDIUM
Memory leak in the keyboard input event handlers support in QEMU (aka Quick Emulator) allows local guest OS privileged users to cause a denial of service (host memory consumption) by rapidly generating large keyboard events.
CVE-2018-17963 4 Canonical, Debian, Qemu and 1 more 6 Ubuntu Linux, Debian Linux, Qemu and 3 more 2021-08-04 7.5 HIGH 9.8 CRITICAL
qemu_deliver_packet_iov in net/net.c in Qemu accepts packet sizes greater than INT_MAX, which allows attackers to cause a denial of service or possibly have unspecified other impact.
CVE-2020-24352 1 Qemu 1 Qemu 2021-07-21 2.1 LOW 5.5 MEDIUM
An issue was discovered in QEMU through 5.1.0. An out-of-bounds memory access was found in the ATI VGA device implementation. This flaw occurs in the ati_2d_blt() routine in hw/display/ati_2d.c while handling MMIO write operations through the ati_mm_write() callback. A malicious guest could use this flaw to crash the QEMU process on the host, resulting in a denial of service.

tcp_emu in tcp_subr.c in libslirp 4.1.0, as used in QEMU 4.2.0, mismanages memory, as demonstrated by IRC DCC commands in EMU_IRC. This can cause a heap-based buffer overflow or other out-of-bounds access which can lead to a DoS or potential execute arbitrary code.
CVE-2008-1945 6 Canonical, Debian, Opensuse and 3 more 9 Ubuntu Linux, Debian Linux, Opensuse and 6 more 2020-12-16 2.1 LOW N/A
QEMU 0.9.0 does not properly handle changes to removable media, which allows guest OS users to read arbitrary files on the host OS by using the diskformat: parameter in the -usbdevice option to modify the disk-image header to identify a different format, a related issue to CVE-2008-2004.
CVE-2007-1321 4 Debian, Fedoraproject, Qemu and 1 more 5 Debian Linux, Fedora, Fedora Core and 2 more 2020-12-15 7.2 HIGH N/A
Integer signedness error in the NE2000 emulator in QEMU 0.8.2, as used in Xen and possibly other products, allows local users to trigger a heap-based buffer overflow via certain register values that bypass sanity checks, aka QEMU NE2000 "receive" integer signedness error. NOTE: this identifier was inadvertently used by some sources to cover multiple issues that were labeled "NE2000 network driver and the socket code," but separate identifiers have been created for the individual vulnerabilities since there are sometimes different fixes; see CVE-2007-5729 and CVE-2007-5730.
CVE-2007-1320 5 Debian, Fedoraproject, Opensuse and 2 more 6 Debian Linux, Fedora, Fedora Core and 3 more 2020-12-15 7.2 HIGH N/A
Multiple heap-based buffer overflows in the cirrus_invalidate_region function in the Cirrus VGA extension in QEMU 0.8.2, as used in Xen and possibly other products, might allow local users to execute arbitrary code via unspecified vectors related to "attempting to mark non-existent regions as dirty," aka the "bitblt" heap overflow.
