Debian DSA-2608-1 : qemu - buffer overflow

high Nessus Plugin ID 63557
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

The remote Debian host is missing a security-related update.

Description

It was discovered that the e1000 emulation code in QEMU does not enforce frame size limits in the same way as the real hardware does.
This could trigger buffer overflows in the guest operating system driver for that network card, assuming that the host system does not discard such frames (which it will by default).

Solution

Upgrade the qemu packages.

For the stable distribution (squeeze), this problem has been fixed in version 0.12.5+dfsg-3squeeze3.
