DEBIAN-CVE-2021-27379

An issue was discovered in Xen through 4.11.x, allowing x86 Intel HVM guest OS users to achieve unintended read/write DMA access, and possibly cause a denial of service host OS crash or gain privileges. This occurs because a backport missed a flush, and thus IOMMU updates were not always correct...

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 the QEMU process on the host resulting in a denial of service condition or potentially execute arbitrary code with privileges of the QEMU process on the host.
