| 제목 | Tomato by Shibby Tomato Firmware 1.28 Stack-based Buffer Overflow |
|---|
| 설명 | usr/sbin/ripd receives zebra routing updates over the local Unix domain socket /tmp/.zserv. In the rip_zebra_read_ipv4 receive path, the daemon reads an attacker-controlled one-byte prefix length, computes ((plen + 7) >> 3), and uses that value as the byte count for a stack copy into a region that has only about 8 safe bytes before saved registers begin.
Because the implementation does not clamp IPv4 prefix length to <= 32 and does not validate the derived byte count against the actual local destination size, a crafted zserv frame can overwrite saved registers and the saved return address. |
