A flaw was reported in how the Subversion FSFS repository handled the packing of revision properties.  When one or more revision properties of a packed revision are set to new, larger values, a "pack file" in the repository might get split.  While this is happening, it is possible that the wrong pack file gets deleted, which can lead to data loss of revision property data.

This issue only affects FSFS repositories in Subversion 1.8.0 and 1.8.1.  It does not affect BDB repositories or earlier versions of Subversion.
