NVD Description
Note: Versions mentioned in the description apply only to the upstream libcacard-tools package and not the libcacard-tools package as distributed by RHEL.
See How to fix? for RHEL:7 relevant fixed versions and status.
A stack based buffer overflow was found in the virtio-net device of QEMU. This issue occurs when flushing TX in the virtio_net_flush_tx function if guest features VIRTIO_NET_F_HASH_REPORT, VIRTIO_F_VERSION_1 and VIRTIO_NET_F_MRG_RXBUF are enabled. This could allow a malicious user to overwrite local variables allocated on the stack. Specifically, the out_sg variable could be used to read a part of process memory and send it to the wire, causing an information leak.
