All supported architectures
Multiple vulnerabilities have been discovered in Bochs, possibly allowing
for the execution of arbitrary code or a Denial of Service.
Bochs is a IA-32 (x86) PC emulator written in C++.
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
A local attacker in the guest operating system could exploit these
issues to execute code outside of the virtual machine, or cause Bochs
There is no known workaround at this time.
All Bochs users should upgrade to the latest version:
Code Listing 3.1: Resolution
# emerge --sync
# emerge --ask --oneshot --verbose ">=app-emulation/bochs-2.3"
