CVE-2020-1711
An out-of-bounds heap buffer access flaw was found in the way the iSCSI Block driver in QEMU handled a response coming from an iSCSI server while checking the status of a Logical Address Block (LBA) in an iscsi_co_block_status() routine. A remote user could use this flaw to crash the QEMU process, resulting in a denial of service or potential execution of arbitrary code with privileges of the QEMU process on the host.
CVE-2020-13253
An out-of-bounds read access issue was found in the SD Memory Card emulator of the QEMU. It occurs while performing block write commands via sdhci_write(), if a guest user has sent address which is OOB of 's->wp_groups'. A guest user/process may use this flaw to crash the QEMU process resulting in DoS.
CVE-2020-14364
An out-of-bounds read/write access issue was found in the USB emulator of the QEMU. It occurs while processing USB packets from a guest, when 'USBDevice->setup_len' exceeds the USBDevice->data_buf[4096], in do_token_{in,out} routines.
CVE-2020-16092
An assertion failure can occur in the network packet processing. This issue affects the e1000e and vmxnet3 network devices. A malicious guest user/process could use this flaw to abort the QEMU process on the host, resulting in a denial of service condition in net_tx_pkt_add_raw_fragment in hw/net/net_tx_pkt.c
For Debian 9 stretch, these problems have been fixed in version 1:2.8+dfsg-6+deb9u11.
We recommend that you upgrade your qemu packages.
For the detailed security status of qemu please refer to its security tracker page at: [link moved to references]
Further information about Debian LTS security advisories, how to apply these updates to your system and frequently asked questions can be found at: [link moved to references]");
