DSA-2607-1 qemu-kvm -- buffer overflow

Debian Security Advisory

DSA-2607-1 qemu-kvm -- buffer overflow

Date Reported:

15 Jan 2013

Affected Packages:

qemu-kvm

Vulnerable:

Yes

Security database references:

In the Debian bugtracking system: Bug 696051.
In Mitre's CVE dictionary: CVE-2012-6075.

More information:

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).

For the stable distribution (squeeze), this problem has been fixed in version 0.12.5+dfsg-5+squeeze10.

For the unstable distribution (sid), this problem has been fixed in version 1.1.2+dfsg-4.

We recommend that you upgrade your qemu-kvm packages.
