CVE request -- libvirt: virBitmapParse out-of-bounds read access

[Petr Matousek <pmatouse () redhat com>]

The virBitmapParse function was calling virBitmapIsSet() function that
requires the caller to check the bounds of the bitmap without checking
them. This resulted into crashes when parsing a bitmap string that was
exceeding the bounds used as argument.
