https://notcve.org/view.php?id=CVE-2017-2620
Quick emulator (QEMU) before 2.8 built with the Cirrus CLGD 54xx VGA Emulator support is vulnerable to an out-of-bounds access issue. The issue could occur while copying VGA data in cirrus_bitblt_cputovideo. A privileged user inside guest could use this flaw to crash the QEMU process OR potentially execute arbitrary code on host with privileges of the QEMU process. Quick emulator (QEMU) en versiones anteriores a la 2.8 construido con el soporte del emulador Cirrus CLGD 54xx VGA Emulator es vulnerable a un problema de acceso fuera de límites. El problema puede ocurrir al copiar datos VGA en cirrus_bitblt_cputovideo. • http://rhn.redhat.com/errata/RHSA-2017-0328.html http://rhn.redhat.com/errata/RHSA-2017-0329.html http://rhn.redhat.com/errata/RHSA-2017-0330.html http://rhn.redhat.com/errata/RHSA-2017-0331.html http://rhn.redhat.com/errata/RHSA-2017-0332.html http://rhn.redhat.com/errata/RHSA-2017-0333.html http://rhn.redhat.com/errata/RHSA-2017-0334.html http://rhn.redhat.com/errata/RHSA-2017-0350.html http://rhn.redhat.com/errata/RHSA-2017-0351.html http://rhn • CWE-125: Out-of-bounds Read CWE-787: Out-of-bounds Write •
