Summary

A denial of service attack might be launched against the server if an unusually lengthy password (more than 10000000 characters) is supplied using the osTicket application. This can cause the website to go down or stop responding. When a long password is entered, this procedure will consume all available CPU and memory.

Fencer Vulns keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.
