CVE-2023-28097

OpenSIPS is a Session Initiation Protocol (SIP) server implementation.
Prior to versions 3.1.9 and 3.2.6, a malformed SIP message containing a
large Content-Length value and a specially crafted Request-URI causes a
segmentation fault in OpenSIPS. This issue occurs when a large amount of
shared memory using the -m flag was allocated to OpenSIPS, such as 10 GB
of RAM. On the test system, this issue occurred when shared memory was set
to 2362 or higher. This issue is fixed in versions 3.1.9 and 3.2.6. The
only workaround is to guarantee that the Content-Length value of input
messages is never larger than 2147483647.
