CVE-2020-17380: Buffer Overflow
First published: Thu Jul 30 2020(Updated: )
A heap-based buffer overflow vulnerability was found in QEMU in the SDHCI device emulation support. It could occur while doing a multi block SDMA transfer via sdhci_sdma_transfer_multi_blocks() routine. 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.
