Description Agostino Sarubbo gentoo-dev 2012-09-13 09:18:42 UTC
From secunia at $URL:

halfdog has reported a vulnerability in Oracle VirtualBox, which can be exploited by malicious, local users in a guest virtual machine to cause a DoS (Denial of Service).

The vulnerability is caused due to a NULL-pointer dereference error when calling the task-gate via IDT (software interrupt) with insufficient privileges in a processor missing VT-x / AMD-V extensions and can be exploited to cause a crash.

The vulnerability is reported in versions prior to 4.1.22.

Update to version 4.1.22.

Arches please test and mark stable the following packages:


Target keywords are:
amd64 x86

Although only app-emulation/virtualbox{,-bin} are affected we need all these packages stable as they are:
  - a dependency of app-emulation/virtualbox{,-bin}
  - need to stay in sync with the rest of the packages
Comment 2 Richard Freeman gentoo-dev 2012-09-14 13:44:22 UTC
I'm not sure if all need to be kept in sync.  For amd64 I've tested and can stabilize:
