Description Agostino Sarubbo gentoo-dev 2016-09-26 12:13:22 UTC
From ${URL} :

The .receive callback of xlnx.xps-ethernetlite doesn't check the length of data before calling memcpy. As a result, the NetClientState object in heap 
will be overflowed. All versions of qemu with xlnx.xps-ethernetlite are affected.

Upstream patch:;a=commit;h=a0d1cbdacff5df4ded16b753b38fdd9da6092968

CVE assignment:

@maintainer(s): after the bump, in case we need to stabilize the package, please let us know if it is ready for the stabilization or not.
Comment 1 Matthias Maier gentoo-dev 2016-09-27 02:03:01 UTC
This patch already made it into the 2.7.0 release of qemu. Currently stable version in tree is 2.7.0-r3 with no vulnerable version left in the tree.
