libvirt: double free in qemuAgentGetInterfaces() in qemu_agent.c

A double free memory issue was found to occur in the libvirt API responsible for requesting information about network interfaces of a running QEMU domain. This flaw affects the polkit access control driver. Specifically, clients connecting to the read-write socket with limited ACL permissions cou...

QEMU: ide: atapi: OOB access while processing read commands

An out-of-bounds read-access flaw was found in the ATAPI Emulator of QEMU. This issue occurs while processing the ATAPI read command if the logical block addressLBA is set to an invalid value. A guest user may use this flaw to crash the QEMU process on the host resulting in a denial of service...

QEMU: heap buffer overflow in iscsi_aio_ioctl_cb() in block/iscsi.c may lead to information disclosure

A heap buffer overflow flaw was found in the iSCSI support of QEMU. This flaw could lead to an out-of-bounds read access and possible information disclosure from the QEMU process memory to a malicious guest. The highest threat from this vulnerability is to data confidentiality...

QEMU: reachable assertion failure in net_tx_pkt_add_raw_fragment() in hw/net/net_tx_pkt.c

An assertion failure flaw was found in QEMU in the network packet processing component. This issue affects the "e1000e" and "vmxnet3" network devices. This flaw allows a malicious guest user or process to abort the QEMU process on the host, resulting in a denial of service...
