Description Agostino Sarubbo gentoo-dev 2017-02-15 10:31:17 UTC
From ${URL} :

Quick emulator(Qemu) built with the SDHCI device emulation support is vulnerable
to an infinite loop issue. It could occur while doing a multi block SDMA
transfer via 'sdhci_sdma_transfer_multi_blocks' routine.

A privileged user inside guest could use this flaw to crash the Qemu process
resulting in DoS.

Upstream patch:


@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.
