Debian DSA-2608-1 : qemu - buffer overflow

high Nessus Plugin ID 63557

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.
