Title: Bochs: Multiple vulnerabilities (GLSA 200711-21)
Date: November 17, 2007
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++.
Vulnerable: < 2.3
Unaffected: >= 2.3
Architectures: All supported architectures
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).
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.
There is no known workaround at this time.
All Bochs users should upgrade to the latest version:
|# emerge --sync
# emerge --ask --oneshot --verbose ">=app-emulation/bochs-2.3"
