Amazon Linux 2023 : perl-Net-DNS, perl-Net-DNS-Nameserver, perl-Net-DNS-tests (ALAS2023-2026-2046)

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2026-2046 advisory. Net::DNS versions through 1.55 for Perl allow remote execution injection via EDNS EXTENDED ERROR. Net::DNS::RR::OPT::EXTENDEDERROR::decompose parses the EXTRA-TEXT field of an EDNS...

Amazon Linux 2 : perl-Net-DNS, --advisory ALAS2-2026-3855 (ALAS-2026-3855)

The version of perl-Net-DNS installed on the remote host is prior to 0.72-6. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2026-3855 advisory. Net::DNS versions through 1.55 for Perl allow Denial of Service via deep DNS compression pointer chains...

Important: perl-Net-DNS

Issue Overview: Net::DNS versions through 1.55 for Perl allow remote execution injection via EDNS EXTENDED ERROR. Net::DNS::RR::OPT::EXTENDEDERROR::decompose parses the EXTRA-TEXT field of an EDNS EXTENDED-ERROR option RFC 8914 by tokenising the raw bytes and passing the result to Perl's eval...

Security update for perl-Net-DNS

This update for perl-Net-DNS fixes the following issue: CVE-2026-64194: RFC 1035 compression pointers are followed via recursion with no depth limit established, which can lead to DoS when specially crafted DNS packets are parsed bsc1272214. Patch Instructions: To install this SUSE update use the...

CVE-2026-64194

Net::DNS versions through 1.55 for Perl allow Denial of Service via deep DNS compression pointer chains. Net::DNS::DomainName::decode follows RFC 1035 compression pointers by recursing into itself with no depth limit. It is possible to construct a name which saturates the call stack at least with...

CVE-2026-14461

A flaw was found in mtr. A remote attacker, by influencing the DNS Domain Name System TXT response used for AS Autonomous System lookups, can trigger an out-of-bound read vulnerability in the ipinfolookup function. This occurs when a DNS response larger than 512 bytes contains a crafted compressi...

CVE-2026-47180

CVE-2026-47180 affects the Zeroconf Python library. The vulnerability stems from DNSIncoming._decode_labels_at_offset recursing for each DNS-name compression pointer; a crafted mDNS packet with ~1500 chained pointers can cause unbounded recursion, escaping DNSIncoming.init and triggering sustaine...

PYSEC-2026-3436 zeroconf has unbounded recursion in DNS compression-pointer decoder that allows LAN-local denial of service

Impact DNSIncoming.decodelabelsatoffset recurses once per DNS-name compression pointer RFC 1035 §4.1.4. Pointer cycles and label counts were capped, but the chain length of unique forward pointers was not. A single 3 kB mDNS packet carrying 1500 chained pointers drives the recursion past CPython'...

CVE-2026-14461

The CVE-2026-14461 entry affects mtr up to version 0.96, where ipinfo_lookup() performs DNS AS lookups and can be triggered by a TXT response larger than 512 bytes with a crafted compression pointer, causing an out-of-bounds read. The function uses the response length as the end-of-message bounda...
