Debian Security Advisory
DLA-1350-1 qemu-kvm -- LTS security update
- Date Reported:
- 17 Apr 2018
- Affected Packages:
- Security database references:
- In the Debian bugtracking system: Bug 892041.
In Mitre's CVE dictionary: CVE-2018-7550.
- More information:
The load_multiboot function in hw/i386/multiboot.c in Quick Emulator (aka QEMU) allows local guest OS users to execute arbitrary code on the QEMU host via a mh_load_end_addr value greater than mh_bss_end_addr, which triggers an out-of-bounds read or write memory access.
For Debian 7
Wheezy, these problems have been fixed in version 1.1.2+dfsg-6+deb7u25.
We recommend that you upgrade your qemu-kvm packages.
