OpenSIPS is a Session Initiation Protocol (SIP) server implementation. Prior to versions 3.1.8 and 3.2.5, when a specially crafted SIP message is processed by the function rewrite_ruri, a crash occurs due to a segmentation fault. This issue causes the server to crash. It affects configurations containing functions that make use of the affected code, such as the function setport. This issue has been fixed in version 3.1.8 and 3.2.5.
