Multiple use-after-free vulnerabilities in vnc.c in the VNC server in QEMU
0.10.6 and earlier might allow guest OS users to execute arbitrary code on
the host OS by establishing a connection from a VNC client and then (1)
disconnecting during data transfer, (2) sending a message using incorrect
integer data types, or (3) using the Fuzzy Screen Mode protocol, related to
double free vulnerabilities.
Notes
| Author | Note |
|---|---|
| jdstrand | versions 0.9.1 and earlier are not affected. Need the following commit to be affected: http://git.savannah.gnu.org/cgit/qemu.git/commit/?id=753b405331. This came in 0.10.0 (from ChangeLog: ‘Multiple VNC clients are now supported’) kvm-84 as included in Ubuntu 9.04 does not contain the affected code (it has a pre-release version of qemu 0.10.0) kvm-84 in hardy-backports and intrepid-backports are not affected (they are based on kvm-84 from Ubuntu 9.04) simply search for VncDisplay in vnc.c to see if might be affected |
