CVE-2016-9384 [MEDIUM] CVE-2016-9384 xsa194 xen: guest 32-bit ELF symbol table load leaking host data (XSA-194)
CVE-2016-9384 xsa194 xen: guest 32-bit ELF symbol table load leaking host data (XSA-194)
ISSUE DESCRIPTION
Along with their main kernel binary, unprivileged guests may arrange
to have their Xen environment load (kernel) symbol tables for their
use. The ELF image metadata created for this purpose has a few unused
bytes when the symbol table binary is in 32-bit ELF format. These
unused bytes were not properly cleared during symbol table loading.
IMPACT
A malicious unprivileged guest may be able to obtain sensitive
information from the host.
The information leak is small and not under the control of the guest,
so effectively exploiting this vulnerability is probably difficult.
VULNERABLE SYSTEMS
Only Xen version 4.7 is affected. Xen versions 4.6 and earlier are not
affected.
