Detailsinfo

A vulnerability has been found in Fabrice Bellard QEMU 0.8.2 (Virtualization Software) and classified as critical. Affected by this vulnerability is an unknown function. The manipulation with an unknown input leads to a memory corruption vulnerability. The CWE definition for the vulnerability is CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

The NE2000 emulator in QEMU 0.8.2 allows local users to execute arbitrary code by writing Ethernet frames with a size larger than the MTU to the EN0_TCNT register, which triggers a heap-based buffer overflow in the slirp library, aka NE2000 "mtu" heap overflow. NOTE: some sources have used CVE-2007-1321 to refer to this issue as part of "NE2000 network driver and the socket code," but this is the correct identifier for the mtu overflow vulnerability.

The bug was discovered 11/01/2007. The weakness was disclosed 05/01/2007 by Tavis Ormandy (Website). It is possible to read the advisory at vupen.com. This vulnerability is known as CVE-2007-5729 since 10/30/2007. Attacking locally is a requirement. The successful exploitation requires a single authentication. The technical details are unknown and an exploit is not publicly available.

It is declared as proof-of-concept. The vulnerability scanner Nessus provides a plugin with the ID 25151 (Debian DSA-1284-1 : qemu - several vulnerabilities), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Debian Local Security Checks and running in the context l. The commercial vulnerability scanner Qualys is able to test this issue with plugin 165646 (SUSE Enterprise Linux Security Update (SUSE-SR:2009:002)).

Upgrading eliminates this vulnerability. A possible mitigation has been published before and not just after the disclosure of the vulnerability.

The vulnerability is also documented in the databases at X-Force (38238), Tenable (25151), SecurityFocus (BID 23731†), OSVDB (42986†) and Secunia (SA27486†). The entries VDB-36553, VDB-36552, VDB-36551 and VDB-39488 are pretty similar. Be aware that VulDB is the high quality source for vulnerability data.
