CWE-126

Description

An attacker might be able to trigger an out-of-bounds read by sending a crafted DNS response packet, when custom Lua code uses newDNSPacketOverlay to parse DNS packets. The out-of-bounds read might trigger a crash, leading to a denial of service, or access unrelated memory, leading to potential information disclosure.

Affected configurations

• powerdns dnsdist (>= 1.9.0 < 1.9.12) • powerdns dnsdist (>= 2.0.0 < 2.0.3)
