Threats affecting pkg:github/libtins

CVE-2026-112274 is an out-of-bounds read vulnerability in libtins up to version 4.6. It occurs in the DNS::soa_record::init function when processing SOA data that lacks NUL terminators. Remote attackers can exploit this by supplying raw SOA RDATA without a zero byte, causing strlen to read beyond the buffer and potentially crash the application.

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.
