OpenSIPS has vulnerability in the codec_delete_XX() functions
Publisher and source text is retained separately from QFinch interpretation.
QFinch assessment
OpenSIPS is a Session Initiation Protocol (SIP) server implementation. Prior to versions 3.1.7 and 3.2.4, OpenSIPS crashes when a malformed SDP body is received and is processed by the `delete_sdp_line` function in the sipmsgops module. This issue can be reproduced by calling the function with an SDP body that does not terminate by a line feed (i.e. `\n`).
