Bochs: Multiple vulnerabilities

Background

Bochs is a IA-32 (x86) PC emulator written in C++.

Description

Tavis Ormandy of the Google Security Team discovered a heap-based overflow vulnerability in the NE2000 driver (CVE-2007-2893). He also discovered a divide-by-zero error in the emulated floppy disk controller (CVE-2007-2894).

Impact

A local attacker in the guest operating system could exploit these issues to execute code outside of the virtual machine, or cause Bochs to crash.

Workaround

There is no known workaround at this time.

Resolution

All Bochs users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=app-emulation/bochs-2.3"
