CVE-2026-112274 Details
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.
A memory safety vulnerability allowing out-of-bounds read has been identified in libtins versions through 4.6. This issue arises within the DNS SOA record initialization process, where the absence of NUL terminators in SOA data can lead to heap buffer overreads. Attackers can exploit this by providing raw SOA RDATA lacking a zero byte, causing the library to read past allocated buffer bounds. The vulnerability is triggered when the affected application processes DNS packets using the libtins library, particularly through the DNS dissector.
Users can upgrade to libtins version 4.7 or later, where this vulnerability has been addressed.
