Suricata 5.0.3 released

We are pleased to announce the release of Suricata 5.0.3. This is a larger than usual point release, with a number of important fixes.

This is the first release after Suricata joined the Oss-Fuzz program, leading to discovery of a number of (potential) security issues. We expect that in the coming months we’ll fix more such issues, as the fuzzers increase their coverage and we continue to improve the seed corpus.
