NVD Description

Note: Versions mentioned in the description apply only to the upstream libtins package and not the libtins package as distributed by Echo. See How to fix? for Echo:latest relevant fixed versions and status.

libtins through 4.6 contains a heap out-of-bounds read vulnerability in DNS::compose_name in src/dns.cpp that allows remote attackers to read past the packet buffer by sending a label ending exactly at the packet end. Attackers can deliver crafted DNS packets whose additional, answer, or authority records trigger a one-byte read when parsed, crashing applications on hardened allocators.
