19 Feb 2019 — QEMU, through version 2.10 and through version 3.1.0, is vulnerable to an out-of-bounds read of up to 128 bytes in the hw/i2c/i2c-ddc.c:i2c_ddc() function. A local attacker with permission to execute i2c commands could exploit this to read stack memory of the qemu process on the host. QEMU, hasta la versión 2.10 y la 3.1.0, es vulnerable a una lectura fuera de límites de hasta 128 bytes en la función hw/i2c/i2c-ddc.c:i2c_ddc().
