En resumen
- CVE-2018-12018 es una vulnerabilidad ALTO (CVSS 7.5) que afecta a github.com/ethereum/go-ethereum, go ethereum (ethereum).
- Probabilidad de explotación en los próximos 30 días (EPSS): 4.3%, mayor que el 91.1% de las vulnerabilidades.
- Solución: actualizar a 1.8.11 o posterior.
Description
The GetBlockHeadersMsg handler in the LES protocol implementation in Go Ethereum (aka geth) before 1.8.11 may lead to an access violation because of an integer signedness error for the array index, which allows attackers to launch a Denial of Service attack by sending a packet with a -1 query.Skip value. The vulnerable remote node would be crashed by such an attack immediately, aka the EPoD (Ethereum Packet of Death) issue.
