| 제목 | dnsmasq v2.73rc6 NULL Pointer Dereference |
|---|
| 설명 | dnsmasq v2.73rc6 contains a null pointer write in parse_dhcp_opt() when handling OPTION_SIP_SERVER. If the configuration provides an empty or otherwise invalid text value such that the builder buffer m is never allocated, the code still executes m[0] = 0, writing to NULL and crashing during startup. Reproduce by replacing dnsmasq.conf with the provided file and launching ./dnsmasq (AFLNet seed result4/id:19 also triggers the same path). |
