EPSS is 0.44% for the current model date.
Compensating controls
Validate the affected product branch and deploy the verified fixed release.
Restrict the affected network interface to trusted sources where business-safe.
Monitor vendor guidance and exploitation sources for a material change.
Verification
Confirm that the asset runs The GNU C Library glibc and falls inside the recorded affected range.
Verify the installed build against the product-specific fixed version after deployment.
Validate exposure, authentication requirements and compensating controls in the actual environment.
Reopen this reassessment when CVSS, KEV, EPSS, exploit evidence or remediation changes.

Summary
The deprecated functions ns_printrrf, ns_printrr and fp_nquery in the GNU C Library version 2.0.1 to version 2.43 fail to validate the RDATA content against the RDATA length in a DNS response when processing A6, CERT, LOC, TKEY or TSIG records, which may allow an attacker to craft a DNS response, causing a target application to crash or read uninitialized memory. These functions are for application debugging only and hence not in the path of code executed by the DNS resolver. Further, they have been deprecated since version 2.34 and should not be used by any new applications. Applications should consider porting away from these interfaces since they may be removed in future versions.

Summary
A flaw was found in glibc (GNU C Library). The deprecated functions ns_printrrf, ns_printrr, and fp_nquery do not properly validate the length of RDATA (Resource Record Data) in a DNS (Domain Name System) response when processing specific record types like LOC, CERT, TKEY, or TSIG. A remote attacker could craft a malicious DNS response, leading to a target application crashing or reading uninitialized memory. These functions are intended for application debugging and are not part of the standard DNS resolver path.

What, why and how
The deprecated functions ns_printrrf, ns_printrr and fp_nquery in the GNU C Library version 2.0.1 to version 2.43 fail to validate the RDATA content against the RDATA length in a DNS response when processing A6, CERT, LOC, TKEY or TSIG records, which may allow an attacker to craft a DNS response, causing a target application to crash or read uninitialized memory.

Why
The product reads from a buffer using buffer access mechanisms such as indexes or pointers that reference memory locations after the targeted buffer.
How
An attacker operating through a network path may attempt exploitation without authentication or user interaction. If successful, the issue may disrupt the affected service.

Exploit reality and attack path
CVSS severity, EPSS forecast probability, public exploit material and CISA-confirmed exploitation are separate signals.
Observed exploitation ?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.No confirmed evidence
No CISA KEV match was present at the last successful refresh. This means no confirmation from that source, not proof of no exploitation.
Public PoC / exploit material ?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.None recorded
No exploit-tagged reference or CISA SSVC proof-of-concept state is currently recorded. Research may still exist outside the structured feeds.

GNU Cライブラリのバージョン2.2以降において、非推奨の関数ns_printrrf、ns_printrrおよびfp_nqueryは、LOC、CERT、TKEY、TSIGレコードを処理する際にDNS応答中のRDATAの内容とRDATA長を検証しません。このため、攻撃者が細工したDNS応答を作成し、ターゲットアプリケーションをクラッシュさせたり、未初期化メモリを読み取らせたりする可能性があります。これらの関数はアプリケーションのデバッグ専用であり、DNSリゾルバによって実行されるコード経路には含まれていません。さらに、これらはバージョン2.34以降非推奨となっており、新しいアプリケーションでの使用は推奨されていません。将来的に削除される可能性があるため、アプリケーションはこれらのインターフェースからの移行を検討すべきです。
Operational remediation based on structured source evidence.
Status ?Patch availability is based on structured fixed-version fields and authoritative update references. If no fix is verified, check the vendor advisory before making a change.
Use the product-specific evidence above. Patch only products with a verified fixed release, and keep every affected or under-investigation state without a matching fix in the remediation queue.
Workaround
No verified workaround is recorded. If business-safe, reduce exposure to the affected interface and allow only trusted sources until authoritative guidance is available.
