CVE-2026-112274 · libtins through 4.6 Out-of-Bounds Read via DNS::soa_record::init
This page contains facts from public vulnerability sources. Check the original advisory before updating.
libtins through 4.6 contains an out-of-bounds read vulnerability in DNS::soa_record::init that allows remote attackers to read past buffer bounds by supplying SOA data lacking NUL terminators. Attackers can feed raw SOA RDATA without a zero byte to applications using the buffer constructor, causing strlen to overrun the heap buffer and possibly crash.
