Description OSIDB Bzimport 2026-01-08 06:28:43 UTC 
A NULL pointer dereference vulnerability exists in the SendingMessage function of SIPp v3.7.3. When SIPp processes specially crafted SIP messages replayed during an active call scenario, insufficient validation of internal message structures can lead to dereferencing a NULL pointer, triggering a segmentation fault. This flaw can be reliably reproduced using a malformed SIP proof-of-concept and AFLNet replay tooling. Under certain memory layout and runtime conditions, this crash may be exploitable to achieve local arbitrary code execution, impacting the integrity and availability of the system running SIPp.
Comment 1 Peter Lemenkov 2026-01-23 00:56:35 UTC 
This issue was fixed in commit 6ff1a322843c0f82e64abebfc7fea69e58204fa5 which initialized previously uninitialized members in the SendingMessage class.

The fix is included in version 3.7.6, and the packages were built and released several weeks ago.
