https://notcve.org/view.php?id=CVE-2021-22945
When sending data to an MQTT server, libcurl <= 7.73.0 and 7.78.0 could in some circumstances erroneously keep a pointer to an already freed memory area and both use that again in a subsequent call to send data and also free it *again*. Cuando se envían datos a un servidor MQTT, libcurl versiones anteriores a 7.73.0, incluyéndola y 7.78.0, podría en algunas circunstancias, mantener erróneamente un puntero a un área de memoria ya liberada y usarlo de nuevo en una llamada posterior para enviar datos y también liberarlo *de nuevo* • http://seclists.org/fulldisclosure/2022/Mar/29 https://cert-portal.siemens.com/productcert/pdf/ssa-389290.pdf https://hackerone.com/reports/1269242 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/APOAK4X73EJTAPTSVT7IRVDMUWVXNWGD https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/RWLEC6YVEM2HWUBX67SDGPSY4CQB72OE https://security.gentoo.org/glsa/202212-01 https://security.netapp.com/advisory/ntap-20211029-0003 https://support.apple.com& • CWE-415: Double Free •
CVE-2021-22946 – curl: Requirement to use TLS not properly enforced for IMAP, POP3, and FTP protocols
https://notcve.org/view.php?id=CVE-2021-22946
A user can tell curl >= 7.20.0 and <= 7.78.0 to require a successful upgrade to TLS when speaking to an IMAP, POP3 or FTP server (`--ssl-reqd` on the command line or`CURLOPT_USE_SSL` set to `CURLUSESSL_CONTROL` or `CURLUSESSL_ALL` withlibcurl). This requirement could be bypassed if the server would return a properly crafted but perfectly legitimate response.This flaw would then make curl silently continue its operations **withoutTLS** contrary to the instructions and expectations, exposing possibly sensitive data in clear text over the network. Un usuario puede decirle a curl versiones posteriores a 7.20.0 incluyéndola , y versiones anteriores a 7.78.0 incluyéndola, que requiera una actualización con éxito a TLS cuando hable con un servidor IMAP, POP3 o FTP ("--ssl-reqd" en la línea de comandos o "CURLOPT_USE_SSL" configurado como "CURLUSESSL_CONTROL" o "CURLUSESSL_ALL" conlibcurl). Este requisito podría ser omitido si el servidor devolviera una respuesta correctamente diseñada pero perfectamente legítima. Este fallo haría que curl continuara silenciosamente sus operaciones **withoutTLS** en contra de las instrucciones y expectativas, exponiendo posiblemente datos confidenciales en texto sin cifrar a través de la red A flaw was found in curl. • http://seclists.org/fulldisclosure/2022/Mar/29 https://cert-portal.siemens.com/productcert/pdf/ssa-389290.pdf https://hackerone.com/reports/1334111 https://lists.debian.org/debian-lts-announce/2021/09/msg00022.html https://lists.debian.org/debian-lts-announce/2022/08/msg00017.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/APOAK4X73EJTAPTSVT7IRVDMUWVXNWGD https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/RWLEC6YVEM2HWUBX67 • CWE-319: Cleartext Transmission of Sensitive Information CWE-325: Missing Cryptographic Step •
