| 제목 | Kamailio Project Kamailio SIP Server 5.5 NULL Pointer Dereference |
|---|
| 설명 | Kamailio v5.5 crashes during configuration parsing due to a NULL pointer dereference in the `while_cmd` grammar rule. When the `while(...)` expression (`rval_expr`) fails to parse and `$2` is NULL, the error branch still calls `yyerror_at(&$2->fpos, ...)`, leading to a dereference of an invalid pointer inside `yyerror_at()` and a SIGSEGV.Impact: Denial of Service on startup. |
