A vulnerability classified as critical was found in OpenSIPS up to 3.1.8/3.2.5. This vulnerability affects an unknown function of the component Message Handler. The manipulation of the argument Content-Length with an unknown input leads to a integer overflow vulnerability. The CWE definition for the vulnerability is CWE-190. The product performs a calculation that can produce an integer overflow or wraparound, when the logic assumes that the resulting value will always be larger than the original value. This can introduce other weaknesses when the calculation is used for resource management or execution control. As an impact it is known to affect availability. CVE summarizes:

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`.

The weakness was shared 03/16/2023 as GHSA-c6j5-f4h4-2xrq. The advisory is available at github.com. This vulnerability was named CVE-2023-28097 since 03/10/2023. Technical details are known, but there is no available exploit.

Upgrading to version 3.1.9 or 3.2.6 eliminates this vulnerability. Applying the patch 7cab422e2fc648f910abba34f3f0dbb3ae171ff5 is able to eliminate this problem. The bugfix is ready for download at github.com. The best possible mitigation is suggested to be upgrading to the latest version.
