A flaw was discovered in OpenLDAP before 2.4.57 leading to a slapd crash in the Values Return Filter control handling, resulting in denial of service (double free and out-of-bounds read). Se detectó un fallo en OpenLDAP versiones anteriores a 2.4.57, conllevando un bloqueo de slapd en el manejo del control de Values Return Filter, resultando en una denegación de servicio (doble liberación y lectura fuera de límites) • http://seclists.org/fulldisclosure/2021/May/64 http://seclists.org/fulldisclosure/2021/May/65 http://seclists.org/fulldisclosure/2021/May/70 https://bugs.openldap.org/show_bug.cgi?id=9408 https://git.openldap.org/openldap/openldap/-/commit/21981053a1195ae1555e23df4d9ac68d34ede9dd https://git.openldap.org/openldap/openldap/-/tags/OPENLDAP_REL_ENG_2_4_57 https://lists.apache.org/thread.html/r58af02e294bd07f487e2c64ffc0a29b837db5600e33b6e698b9d696b%40%3Cissues.bookkeeper.apache.org%3E https://lists.apache.org • CWE-125: Out-of-bounds Read CWE-415: Double Free •
CVSS: 7.5EPSS: 0%CPEs: 62EXPL: 1CVE-2020-8285 – curl: Malicious FTP server can trigger stack overflow when CURLOPT_CHUNK_BGN_FUNCTION is used
https://notcve.org/view.php?id=CVE-2020-8285
curl 7.21.0 to and including 7.73.0 is vulnerable to uncontrolled recursion due to a stack overflow issue in FTP wildcard match parsing. curl versiones 7.21.0 hasta 7.73.0 e incluyéndola, es vulnerable a una recursividad no controlada debido a un problema de desbordamiento de la pila en el análisis de coincidencias del comodín FTP Libcurl offers a wildcard matching functionality, which allows a callback (set with `CURLOPT_CHUNK_BGN_FUNCTION`) to return information back to libcurl on how to handle a specific entry in a directory when libcurl iterates over a list of all available entries. When this callback returns `CURL_CHUNK_BGN_FUNC_SKIP`, to tell libcurl to not deal with that file, the internal function in libcurl then calls itself recursively to handle the next directory entry. If there's a sufficient amount of file entries and if the callback returns "skip" enough number of times, libcurl runs out of stack space. The exact amount will of course vary with platforms, compilers and other environmental factors. • http://seclists.org/fulldisclosure/2021/Apr/51 https://cert-portal.siemens.com/productcert/pdf/ssa-389290.pdf https://curl.se/docs/CVE-2020-8285.html https://github.com/curl/curl/issues/6255 https://hackerone.com/reports/1045844 https://lists.apache.org/thread.html/r58af02e294bd07f487e2c64ffc0a29b837db5600e33b6e698b9d696b%40%3Cissues.bookkeeper.apache.org%3E https://lists.apache.org/thread.html/rf4c02775860db415b4955778a131c2795223f61cb8c6a450893651e4%40%3Cissues.bookkeeper.apache.org%3E https://lists.debian.org/debian-lts • CWE-121: Stack-based Buffer Overflow CWE-674: Uncontrolled Recursion CWE-787: Out-of-bounds Write •
CVSS: 7.5EPSS: 0%CPEs: 40EXPL: 1CVE-2020-8286 – curl: Inferior OCSP verification
https://notcve.org/view.php?id=CVE-2020-8286
curl 7.41.0 through 7.73.0 is vulnerable to an improper check for certificate revocation due to insufficient verification of the OCSP response. curl versiones 7.41.0 hasta 7.73.0, es vulnerable a una comprobación inapropiada para la revocación del certificado debido a una verificación insuficiente de la respuesta OCSP Libcurl offers "OCSP stapling" via the CURLOPT_SSL_VERIFYSTATUS option. When set, libcurl verifies the OCSP response that a server responds with as part of the TLS handshake. It then aborts the TLS negotiation if something is wrong with the response. The same feature can be enabled with --cert-status using the curl tool. As part of the OCSP response verification, a client should verify that the response is indeed set out for the correct certificate. • http://seclists.org/fulldisclosure/2021/Apr/50 http://seclists.org/fulldisclosure/2021/Apr/51 http://seclists.org/fulldisclosure/2021/Apr/54 https://cert-portal.siemens.com/productcert/pdf/ssa-200951.pdf https://cert-portal.siemens.com/productcert/pdf/ssa-389290.pdf https://curl.se/docs/CVE-2020-8286.html https://hackerone.com/reports/1048457 https://lists.debian.org/debian-lts-announce/2020/12/msg00029.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fe • CWE-295: Improper Certificate Validation •
CVSS: 7.5EPSS: 0%CPEs: 22EXPL: 0CVE-2020-8037 – ppp decapsulator can be convinced to allocate a large amount of memory
https://notcve.org/view.php?id=CVE-2020-8037
The ppp decapsulator in tcpdump 4.9.3 can be convinced to allocate a large amount of memory. El ppp decapsulator en tcpdump versión 4.9.3 puede ser convencido para que asigne una gran cantidad de memoria A flaw was found in tcpdump while printing PPP packets captured in a pcap file or coming from the network. This flaw allows a remote attacker to send specially crafted packets that, when printed, can lead the application to allocate a large amount of memory, resulting in a denial of service. The highest threat from this vulnerability is to system availability. • http://seclists.org/fulldisclosure/2021/Apr/51 https://github.com/the-tcpdump-group/tcpdump/commit/32027e199368dad9508965aae8cd8de5b6ab5231 https://lists.debian.org/debian-lts-announce/2020/11/msg00018.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/F2MX34MJIUJQGL6CMEPLTKFOOOC3CJ4Z https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/LWDBONZVLC6BAOR2KM376DJCM4H3FERV https://support.apple.com/kb/HT212325 https://support.apple.com/kb/HT212326 h • CWE-400: Uncontrolled Resource Consumption CWE-770: Allocation of Resources Without Limits or Throttling •

https://notcve.org/view.php?id=CVE-2013-0340
expat 2.1.0 and earlier does not properly handle entities expansion unless an application developer uses the XML_SetEntityDeclHandler function, which allows remote attackers to cause a denial of service (resource consumption), send HTTP requests to intranet servers, or read arbitrary files via a crafted XML document, aka an XML External Entity (XXE) issue. NOTE: it could be argued that because expat already provides the ability to disable external entity expansion, the responsibility for resolving this issue lies with application developers; according to this argument, this entry should be REJECTed, and each affected application would need its own CVE. expat 2.1.0 y anteriores no maneja adecuadamente entidades de expansión a menos que un desarrollador de aplicaciones use la función XML_SetEntityDeclHandler, esto permite a atacantes remotos provocar una denegación de servicio (consumo de recursos), enviar peticiones HTTP a los servidores de la intranet, o leer archivos arbitrarios a través de un documento XML manipulado, también conocido como problema XML External Entity (XXE) NOTA: se podría argumentar que debido a que expat ya ofrece la posibilidad de desactivar la expansión entidad externa, la responsabilidad de la solución de este problema se encuentra con los desarrolladores de aplicaciones, de acuerdo con este argumento, esta entrada debe ser rechazada, y cada aplicación afectada tendría su propio CVE . • http://openwall.com/lists/oss-security/2013/02/22/3 http://seclists.org/fulldisclosure/2021/Oct/61 http://seclists.org/fulldisclosure/2021/Oct/62 http://seclists.org/fulldisclosure/2021/Oct/63 http://seclists.org/fulldisclosure/2021/Sep/33 http://seclists.org/fulldisclosure/2021/Sep/34 http://seclists.org/fulldisclosure/2021/Sep/35 http://seclists.org/fulldisclosure/2021/Sep/38 http://seclists.org/fulldisclosure/2021/Sep/39 http://seclists.org/fulldisclosure/2021/Sep • CWE-611: Improper Restriction of XML External Entity Reference •
