CVE-2020-17380 (GCVE-0-2020-17380)

Vulnerability from cvelistv5 – Published: 2021-01-30 05:38 – Updated: 2024-08-04 13:53
VLAI
Summary
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.
