CVE-2015-6815  (opens in a new tab)
CWE-835  (opens in a new tab)

How to fix?

Upgrade Debian:8 qemu to version 1:2.1+dfsg-12+deb8u4 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream qemu package and not the qemu package as distributed by Debian. See How to fix? for Debian:8 relevant fixed versions and status.

The process_tx_desc function in hw/net/e1000.c in QEMU before 2.4.0.1 does not properly process transmit descriptor data when sending a network packet, which allows attackers to cause a denial of service (infinite loop and guest crash) via unspecified vectors.
