Description Stefan Behte (RETIRED) gentoo-dev Security 2009-01-04 01:44:44 UTC 
CVE-2008-4539 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2008-4539):
  Heap-based buffer overflow in the Cirrus VGA implementation in (1)
  KVM before kvm-82 and (2) QEMU on Debian GNU/Linux and Ubuntu might
  allow local users to gain privileges by using the VNC console for a
  connection, aka the LGD-54XX "bitblt" heap overflow.  NOTE: this
  issue exists because of an incorrect fix for CVE-2007-1320.
Comment 1 Daniel Gryniewicz (RETIRED) gentoo-dev 2009-01-05 01:32:34 UTC 
82 is added.  This supposedly also fixes CVE-2007-5729 and CVE-2008-2382.
Comment 2 Stefan Behte (RETIRED) gentoo-dev Security 2009-01-05 02:21:50 UTC 
Thanks!
Changing whiteboard to noglsa as it's not a stable package.
