libtins through 4.6 Out-of-Bounds Read via DNS::soa_record::init

Published Oct 19, 2026 CVSS 4.0 · 6.3 Medium EPSS < 1% KEV · Not listed
Description
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.
