Multiple buffer overflows in the ssd0323_load function in hw/display/ssd0323.c in QEMU before 1.7.2 allow remote attackers to cause a denial of service (memory corruption) or possibly execute arbitrary code via crafted (1) cmd_len, (2) row, or (3) col values; (4) row_start and row_end values; or (5) col_star and col_end values in a savevm image.
CVE-2016-9923 1 Qemu 1 Qemu 2025-04-12 5.5 Medium
Quick Emulator (Qemu) built with the 'chardev' backend support is vulnerable to a use after free issue. It could occur while hotplug and unplugging the device in the guest. A guest user/process could use this flaw to crash a Qemu process on the host resulting in DoS.
CVE-2014-5388 2 Canonical, Qemu 2 Ubuntu Linux, Qemu 2025-04-12 N/A
Off-by-one error in the pci_read function in the ACPI PCI hotplug interface (hw/acpi/pcihp.c) in QEMU allows local guest users to obtain sensitive information and have other unspecified impact related to a crafted PCI device that triggers memory corruption.
CVE-2013-4537 1 Qemu 1 Qemu 2025-04-12 N/A
The ssi_sd_transfer function in hw/sd/ssi-sd.c in QEMU before 1.7.2 allows remote attackers to execute arbitrary code via a crafted arglen value in a savevm image.
CVE-2013-4527 2 Qemu, Redhat 3 Qemu, Enterprise Linux, Openstack 2025-04-12 N/A
Buffer overflow in hw/timer/hpet.c in QEMU before 1.7.2 might allow remote attackers to execute arbitrary code via vectors related to the number of timers.
