Description

An out-of-bound write access flaw was found in the way QEMU loads ROM contents at boot time. This flaw occurs in the rom_copy() routine while loading the contents of a 32-bit -kernel image into memory. Running an untrusted -kernel image may load contents at arbitrary memory locations, potentially leading to code execution with the privileges of the QEMU process.

Statement

In Red Hat OpenStack Platform, because the flaw has a lower impact and the fix would require a substantial amount of development, no update will be provided at this time for the RHOSP qemu-kvm-rhev package.
