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(). Un atacante local con permisos para ejecutar comandos i2c podría aprovechar este hecho para leer la memoria de pila del proceso qemu en el host. • http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00094.html http://lists.opensuse.org/opensuse-security-announce/2019-05/msg00040.html http://www.securityfocus.com/bid/107059 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2019-3812 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/CGCFIFSIWUREEQQOZDZFBYKWZHXCWBZN https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/KJMTVGDLA654HNCDGLCUEIP36SNJEKK7 https://seclists.org/bugtraq&# • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-125: Out-of-bounds Read •
