A vulnerability was found in HdrHistogram up to 2.2.2. This issue affects the function org.HdrHistogram.DoubleHistogram.recordValue of the file src/main/java/org/HdrHistogram/DoubleHistogram.java of the component Range Check. Performing a manipulation results in incorrect comparison. The attack is only possible with local access. The exploit has been made public and could be used. The presence of this vulnerability remains uncertain at this time. This issue is disputed due to the potential lack of crossing of security boundaries and the pre-requisites for a successful attack.
