Description Agostino Sarubbo gentoo-dev 2017-02-16 08:47:21 UTC
From ${URL} :

Quick Emulator(Qemu) built with the Crypto block IV generator - essiv support
is vulnerable to a host memory leakage issue. It could occur while initialising
the crypto device in 'qcrypto_ivgen_essiv_init'.

A guest user/process could use this flaw to leak host memory resulting in DoS.

@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.

This one turned out to be a non security issue, as guest could not trigger this memory leak.

CVE has been cancelled, see https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2017-6000
