CVE-2017-18265
Prosody before 0.10.0 allows remote attackers to cause a denial of service (application crash), related to an incompatibility with certain versions of the LuaSocket library, such as the lua-socket package from Debian stretch.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.73%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
