CVSS 7.5 · High EPSS 0,66%

Kerentanan NULL Pointer Dereference pada coredns.io coredns. Skor CVSS 3.1 7.5 (High) menurut github.com.

Deskripsi (NVD)

CoreDNS is a DNS server written in Go. Prior to 1.14.4, a single 28-byte UDP datagram can crash the CoreDNS process when the proxyproto plugin is enabled because plugin/pkg/proxyproto/proxyproto.go PacketConn.ReadFrom handles a PROXY v2 header with non-UDP transport such as family byte 0x11, reassigns addr from a nil readFrom result after parseProxyProtocol errors, and calls addr.String() in the warning log before ServeDNS recovery applies. This issue is fixed in version 1.14.4.
