Description Petr Matousek 2013-09-10 17:39:38 UTC 
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.
