Synopsis ========
Multiple vulnerabilities have been discovered in Bochs, possibly allowing for the execution of arbitrary code or a Denial of Service.
Background ==========
Bochs is a IA-32 (x86) PC emulator written in C++.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 app-emulation/bochs < 2.3 >= 2.3
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"
