When ldns version 1.7.1 verifies a zone file, the ldns_rr_new_frm_str_internal function has a heap out of bounds read vulnerability. An attacker can leak information on the heap by constructing a zone file payload. Cuando ldns versión 1.7.1, verifica un archivo de zona, la función ldns_rr_new_frm_str_internal presenta una vulnerabilidad de lectura fuera de límites de la pila. Un atacante puede filtrar información en la pila al construir una carga útil de archivo de zona • https://github.com/NLnetLabs/ldns/commit/15d96206996bea969fbc918eb0a4a346f514b9f3 https://github.com/NLnetLabs/ldns/issues/50 • CWE-125: Out-of-bounds Read •
CVSS: 7.5EPSS: 0%CPEs: 2EXPL: 0CVE-2021-43174 – gzip transfer encoding caused out-of-memory crash
https://notcve.org/view.php?id=CVE-2021-43174
NLnet Labs Routinator versions 0.9.0 up to and including 0.10.1, support the gzip transfer encoding when querying RRDP repositories. This encoding can be used by an RRDP repository to cause an out-of-memory crash in these versions of Routinator. RRDP uses XML which allows arbitrary amounts of white space in the encoded data. The gzip scheme compresses such white space extremely well, leading to very small compressed files that become huge when being decompressed for further processing, big enough that Routinator runs out of memory when parsing input data waiting for the next XML element. NLnet Labs Routinator versiones 0.9.0 hasta la 0.10.1 incluyéndola, soportan una codificación de transferencia gzip cuando se consultan repositorios RRDP. • https://www.debian.org/security/2022/dsa-5041 https://www.nlnetlabs.nl/downloads/routinator/CVE-2021-43172_CVE-2021-43173_CVE-2021-43174.txt • CWE-787: Out-of-bounds Write CWE-1325: Improperly Controlled Sequential Memory Allocation •
CVSS: 7.5EPSS: 0%CPEs: 2EXPL: 0CVE-2021-43173 – Hanging RRDP request
https://notcve.org/view.php?id=CVE-2021-43173
In NLnet Labs Routinator prior to 0.10.2, a validation run can be delayed significantly by an RRDP repository by not answering but slowly drip-feeding bytes to keep the connection alive. This can be used to effectively stall validation. While Routinator has a configurable time-out value for RRDP connections, this time-out was only applied to individual read or write operations rather than the complete request. Thus, if an RRDP repository sends a little bit of data before that time-out expired, it can continuously extend the time it takes for the request to finish. Since validation will only continue once the update of an RRDP repository has concluded, this delay will cause validation to stall, leading to Routinator continuing to serve the old data set or, if in the initial validation run directly after starting, never serve any data at all. • https://www.debian.org/security/2021/dsa-5033 https://www.debian.org/security/2022/dsa-5041 https://www.nlnetlabs.nl/downloads/routinator/CVE-2021-43172_CVE-2021-43173_CVE-2021-43174.txt • CWE-400: Uncontrolled Resource Consumption CWE-755: Improper Handling of Exceptional Conditions •
CVSS: 7.5EPSS: 0%CPEs: 1EXPL: 0CVE-2021-43172 – Infinite length chain of RRDP repositories
https://notcve.org/view.php?id=CVE-2021-43172
NLnet Labs Routinator prior to 0.10.2 happily processes a chain of RRDP repositories of infinite length causing it to never finish a validation run. In RPKI, a CA can choose the RRDP repository it wishes to publish its data in. By continuously generating a new child CA that only consists of another CA using a different RRDP repository, a malicious CA can create a chain of CAs of de-facto infinite length. Routinator prior to version 0.10.2 did not contain a limit on the length of such a chain and will therefore continue to process this chain forever. As a result, the validation run will never finish, leading to Routinator continuing to serve the old data set or, if in the initial validation run directly after starting, never serve any data at all. • https://www.nlnetlabs.nl/downloads/routinator/CVE-2021-43172_CVE-2021-43173_CVE-2021-43174.txt • CWE-674: Uncontrolled Recursion CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop') •
CVSS: 7.5EPSS: 0%CPEs: 1EXPL: 0CVE-2021-41531 – Invalid RPKI data could disable Route Origin Validation on RTR clients.
https://notcve.org/view.php?id=CVE-2021-41531
NLnet Labs Routinator prior to 0.10.0 produces invalid RTR payload if an RPKI CA uses too large values in the max-length parameter in a ROA. This will lead to RTR clients such as routers to reject the RPKI data set, effectively disabling Route Origin Validation. NLnet Labs Routinator versiones anteriores a 0.10.0, produce una carga útil RTR no válida si una CA RPKI usa valores demasiado grandes en el parámetro de longitud máxima en un ROA. Esto conlleva a que los clientes RTR, como los enrutadores, rechacen el conjunto de datos RPKI, deshabilitando efectivamente la Comprobación del Origen de Ruta • https://www.nlnetlabs.nl/downloads/routinator/CVE-2021-41531.txt • CWE-20: Improper Input Validation CWE-1288: Improper Validation of Consistency within Input •
