|---|---|---|---|---|---|---|---|
| CVE-2026-6554 | Med | 5.5 | < 1.10.7-1.1 | 1.10.7-1.1 | Sep 5, 2026 | libpcap BPF interpreter treats the offset in the 'ja L' BPF instruction as a signed integer to implement looping via backward jumps, but it does not limit the number of loop iterations. In particular uncommon use cases a crafted filter program can cause the interpreter to loop i | |
| CVE-2026-6244 | Med | 5.5 | < 1.10.7-1.1 | 1.10.7-1.1 | Sep 5, 2026 | libpcap BPF interpreter for the 'div #k' and 'mod #k' ALU instructions does not check whether the immediate value is zero. In particular uncommon use cases a crafted filter program can cause a division by zero. | |
| CVE-2026-31912 | Med | 5.5 | < 1.10.7-1.1 | 1.10.7-1.1 | Sep 5, 2026 | libpcap BPF interpreter detects neither reaching the end of the filter program buffer due to lack of a return instruction nor executing a jump instruction with an offset that translates to a pointer outside of the buffer. In particular uncommon use cases a crafted filter program | |
| CVE-2026-31911 | Med | 5.5 | < 1.10.7-1.1 | 1.10.7-1.1 | Sep 5, 2026 | libpcap BPF interpreter calls abort() if it encounters a BPF instruction that has an invalid opcode. In particular uncommon use cases a crafted filter program can terminate the OS process. | |
| CVE-2026-18313 | Med | 4.3 | < 1.10.7-1.1 | 1.10.7-1.1 | Sep 5, 2026 | rpcapd can allocate up to 65536 bytes per each RPCAP_MSG_UPDATEFILTER_REQ or RPCAP_MSG_STARTCAP_REQ message received from the client, but it never frees the memory, so it leaks memory even under normal use. A malicious client can cause the server to leak memory substantially fas | |
| CVE-2026-18238 | Med | 5.0 | < 1.10.7-1.1 | 1.10.7-1.1 | Sep 5, 2026 | The rpcap client code that processes a RPCAP_MSG_PACKET message received from the server incorrectly validates its headers. A malicious server can send a crafted message and cause the client to treat up to 20 bytes of the client process memory beyond the end of the buffer as if | |
| CVE-2026-0799 | Hig | 8.7 | < 1.10.7-1.1 | 1.10.7-1.1 | Sep 5, 2026 | In BPF instructions that load/store a value from/to a scratch memory register the register index is an unsigned 32-bit integer and must not exceed 15, but libpcap BPF interpreter does not validate the value. In particular uncommon use cases a crafted filter program can cause the | |

The string argument must be a well-formed MAC-48 address in one of the supported formats, but this requirement has been poorly documented. If an applicat | |
