| 标题 | Kamailio Project Kamailio SIP Server 5.5 NULL Pointer Dereference |
|---|
| 描述 | Kamailio v5.5 contains a NULL pointer dereference in configuration parsing. The parser action for certain expression constructs calls `rve_is_constant($3)` without verifying `$3` is non-NULL; a crafted configuration can make `$3` NULL and cause `rve_is_constant()` to dereference NULL and crash the process. Impact: Denial of Service on startup. |
