Julio,
In other words, 15.0.3 before 15.0.3 ESD#4.3, 15.5 before 15.5 ESD#5.3, and 15.7 before 15.7 SP50 or 15.7 SP100 allows local users to obtain sensitive information via unspecified vectors.
The specific vector in question, network vulnerability not requiring authentication...
So, apply the specific patches and / or upgrade to ASE 16.0 ASAP?
Cheers.
Jean-Pierre
