| Title | Kamailio Project Kamailio SIP Server 5.5 Use After Free |
|---|
| Description | Kamailio v5.5 contains a heap use-after-free in configuration include handling. Malicious or malformed configuration files that exercise `import` / `include` handling can cause Kamailio to read freed memory while parsing configuration (`sr_push_yy_state` / `cfg.lex`), resulting in process crash at startup (Denial of Service) and potential memory-corruption that could be leveraged further. |
