| CVE-2021-20263 | 0.00 | — | 0.00 | Mar 9, 2021 | A flaw was found in the virtio-fs shared file system daemon (virtiofsd) of QEMU. The new 'xattrmap' option may cause the 'security.capability' xattr in the guest to not drop on file write, potentially leading to a modified, privileged executable in the guest. In rare… | |||
| CVE-2021-20203 | 0.00 | — | 0.01 | Feb 25, 2021 | An integer overflow issue was found in the vmxnet3 NIC emulator of the QEMU for versions up to v5.2.0. It may occur if a guest was to supply invalid values for rx/tx queue size or other NIC parameters. A privileged guest user may use this flaw to crash the QEMU process on the… | |||
| CVE-2020-17380 | 0.00 | — | 0.00 | Jan 30, 2021 | A heap-based buffer overflow was found in QEMU through 5.0.0 in the SDHCI device emulation support. It could occur while doing a multi block SDMA transfer via the sdhci_sdma_transfer_multi_blocks() routine in hw/sd/sdhci.c. A guest user or process could use this flaw to crash… | |||
| CVE-2020-35517 | 0.00 | — | 0.01 | Jan 28, 2021 | A flaw was found in qemu. A host privilege escalation issue was found in the virtio-fs shared file system daemon where a privileged guest user is able to create a device special file in the shared directory and use it to r/w access host devices. | |||
