Technical 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.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
