Name of the Vulnerable Software and Affected Versions
QEMU versions 2.10 through 3.1.0
Description
The issue is related to an out-of-bounds read of up to 128 bytes in the
i2c ddc() function, located in the hw/i2c/i2c-ddc.c file. A local attacker with permission to execute i2c commands could exploit this to read stack memory of the qemu process on the host, potentially revealing protected information.Recommendations
For QEMU versions 2.10 through 3.1.0, consider restricting access to the
i2c ddc() function in the hw/i2c/i2c-ddc.c file until a patch is available.
At the moment, there is no information about a newer version that contains a fix for this vulnerability.Out of bounds Read
