Astra Linux – Vulnerability in Qemu

A heap-based buffer overflow was discovered in the SDHCI device emulation of QEMU. The bug is triggered when both s-datacount and the size of s-fifobuffer are set to 0x200, leading to an out-of-bound access. A malicious guest could exploit this flaw to crash the QEMU process on the host, resultin...
