CVE-2019-16779 describes a race condition in RubyGem excon versions prior to 0.71.0, affecting products like Debian and OpenSUSE. This vulnerability allows subsequent requests to receive data from a previous, interrupted connection due to residual data on the socket. Rated as MEDIUM severity (CVSS 5.9), it has a network attack vector and high confidentiality impact, but a high attack complexity due to the short race condition window. There is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or inclusion in the KEV catalog, with minimal community discussion and media coverage.
