| CVE | 概要 | ソース | CVSS 最大値 | EPSS（%） | 公開 | 更新 |
|---|---|---|---|---|---|---|
| CVE-2024-35434 | Irontec Sngrep v1.8.1 was discovered to contain a heap buffer overflow via the function rtp_check_packet at /sngrep/src/rtp.c. This vulnerability allows attackers to cause a Denial of Service (DoS) via a crafted SIP packet. | [email protected] | 7.5 | 0.61% | 2024-05-29 | 2026-06-17 |
| CVE-2024-3120 | A stack-buffer overflow vulnerability exists in all versions of sngrep since v1.4.1. The flaw is due to inadequate bounds checking when copying 'Content-Length' and 'Warning' headers into fixed-size buffers in the sip_validate_packet and sip_parse_extra_headers functions within src/sip.c. This vulnerability allows remote attackers to execute arbitrary code or cause a denial of service (DoS) via crafted SIP messages. | 41c37e40-543d-43a2-b660-2fee83ea851a | 9.0 | 1.80% | 2024-04-09 | 2026-06-17 |
| CVE-2024-3119 | A buffer overflow vulnerability exists in all versions of sngrep since v0.4.2, due to improper handling of 'Call-ID' and 'X-Call-ID' SIP headers. The functions sip_get_callid and sip_get_xcallid in sip.c use the strncpy function to copy header contents into fixed-size buffers without checking the data length. This flaw allows remote attackers to execute arbitrary code or cause a denial of service (DoS) through specially crafted SIP messages. | 41c37e40-543d-43a2-b660-2fee83ea851a | 9.0 | 1.80% | 2024-04-09 | 2026-06-17 |
| CVE-2023-36192 | Sngrep v1.6.0 was discovered to contain a heap buffer overflow via the function capture_ws_check_packet at /src/capture.c. | [email protected] | 7.8 | 0.28% | 2023-06-22 | 2026-06-17 |
| CVE-2023-31982 | Sngrep v1.6.0 was discovered to contain a heap buffer overflow via the function capture_packet_reasm_ip at /src/capture.c. | [email protected] | 7.8 | 0.31% | 2023-05-09 | 2026-06-17 |
| CVE-2023-31981 | Sngrep v1.6.0 was discovered to contain a stack buffer overflow via the function packet_set_payload at /src/packet.c. | [email protected] | 7.8 | 0.31% | 2023-05-09 | 2026-06-17 |
