Description GLSAMaker/CVETool Bot gentoo-dev 2012-08-08 14:10:14 UTC
CVE-2012-2652 (
  The bdrv_open function in Qemu 1.0 does not properly handle the failure of
  the mkstemp function, when in snapshot node, which allows local users to
  overwrite or read arbitrary files via a symlink attack on an unspecified
  temporary file.

Since is marked as [ebuild] would be great if you mention the fixed version next time
Comment 2 Doug Goldstein (RETIRED) gentoo-dev 2012-08-08 17:51:11 UTC
The referenced commit that fixes this appears in the 1.1 release. 1.1.1-r1 is stable on amd64. We're waiting on x86 for bug #428476.
