When parsing a JID, jabberd2 version 2.3.2 and below truncate the data but do not verify whether the result is valid UTF8 before passing it to libidn. If the data ends with an unterminated multi-byte UTF8 sequence then libidn may copy data past the buffer into the result. This can be exploited by remote clients or remote servers. Could you please assign a CVE for this issue?  = https://github.com/jabberd2/jabberd2/issues/85 Best regards, Thijs Alkemade Download attachment "signature.asc" of type "application/pgp-signature" (842 bytes)
