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.
