CVSS: 6.5EPSS: 0%CPEs: 33EXPL: 1CVE-2022-32206 – curl: HTTP compression denial of service
https://notcve.org/view.php?id=CVE-2022-32206
curl < 7.84.0 supports "chained" HTTP compression algorithms, meaning that a serverresponse can be compressed multiple times and potentially with different algorithms. The number of acceptable "links" in this "decompression chain" was unbounded, allowing a malicious server to insert a virtually unlimited number of compression steps.The use of such a decompression chain could result in a "malloc bomb", makingcurl end up spending enormous amounts of allocated heap memory, or trying toand returning out of memory errors. curl versiones anteriores a 7.84.0, soporta algoritmos de compresión HTTP "encadenados", lo que significa que una respuesta al servidor puede ser comprimida múltiples veces y potencialmente con diferentes algoritmos. El número de "eslabones" aceptables en esta "cadena de descompresión" era ilimitado, lo que permitía a un servidor malicioso insertar un número prácticamente ilimitado de pasos de compresión. El uso de una cadena de descompresión de este tipo podía resultar en una "bomba de malloc", haciendo que curl acabara gastando enormes cantidades de memoria de montón asignada, o intentando y devolviendo errores de memoria A vulnerability was found in curl. This issue occurs because the number of acceptable "links" in the "decompression chain" was unbounded, allowing a malicious server to insert a virtually unlimited number of compression steps. • http://seclists.org/fulldisclosure/2022/Oct/28 http://seclists.org/fulldisclosure/2022/Oct/41 http://www.openwall.com/lists/oss-security/2023/02/15/3 https://cert-portal.siemens.com/productcert/pdf/ssa-333517.pdf https://hackerone.com/reports/1570651 https://lists.debian.org/debian-lts-announce/2022/08/msg00017.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/BEV6BR4MTI3CEWK2YU2HQZUW5FAS3FEY https://security.gentoo.org/glsa/202212-01 https:/ • CWE-770: Allocation of Resources Without Limits or Throttling •
CVSS: 9.8EPSS: 0%CPEs: 21EXPL: 1CVE-2022-32207 – curl: Unpreserved file permissions
https://notcve.org/view.php?id=CVE-2022-32207
When curl < 7.84.0 saves cookies, alt-svc and hsts data to local files, it makes the operation atomic by finalizing the operation with a rename from a temporary name to the final target file name.In that rename operation, it might accidentally *widen* the permissions for the target file, leaving the updated file accessible to more users than intended. Cuando curl versiones anteriores a 7.84.0, guarda datos de cookies, alt-svc y hsts en archivos locales, hace que la operación sea atómica al finalizar la operación con un renombramiento de un nombre temporal al nombre final del archivo de destino. En esa operación de renombramiento, podría accidentalmente *ampliar* los permisos del archivo de destino, dejando el archivo actualizado accesible a más usuarios de los previstos A vulnerability was found in curl. This issue occurs because when curl saves cookies, alt-svc, and HSTS data to local files, it makes the operation atomic by finalizing the process with a rename from a temporary name to the final target file name. This flaw leads to unpreserved file permissions, either by mistake or by a malicious actor. • http://seclists.org/fulldisclosure/2022/Oct/28 http://seclists.org/fulldisclosure/2022/Oct/41 https://hackerone.com/reports/1573634 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/BEV6BR4MTI3CEWK2YU2HQZUW5FAS3FEY https://security.gentoo.org/glsa/202212-01 https://security.netapp.com/advisory/ntap-20220915-0003 https://support.apple.com/kb/HT213488 https://www.debian.org/security/2022/dsa-5197 https://access.redhat.com/security/cve/CVE-2022-32207 http • CWE-276: Incorrect Default Permissions CWE-281: Improper Preservation of Permissions CWE-840: Business Logic Errors •

https://notcve.org/view.php?id=CVE-2022-32208
When curl < 7.84.0 does FTP transfers secured by krb5, it handles message verification failures wrongly. This flaw makes it possible for a Man-In-The-Middle attack to go unnoticed and even allows it to inject data to the client. Cuando curl versiones anteriores a 7.84.0, hace transferencias FTP aseguradas por krb5, maneja inapropiadamente los fallos de verificación de mensajes. Este fallo hace posible que un ataque de tipo Man-In-The-Middle pase desapercibido e incluso permite inyectar datos al cliente A vulnerability was found in curl.

Using its HSTS support, curl can be instructed to use HTTPS directly insteadof using an insecure clear-text HTTP step even when HTTP is provided in theURL. This mechanism could be bypassed if the host name in the given URL used atrailing dot while not using one when it built the HSTS cache. Or the otherway around - by having the trailing dot in the HSTS cache and *not* using thetrailing dot in the URL. usando su soporte HSTS, curl puede ser instruido para usar HTTPS directamente en lugar de usar un paso no seguro de texto sin cifrar HTTP incluso cuando HTTP es proporcionado en la URL. Este mecanismo podría ser omitido si el nombre de host en la URL dada usara un endpoint mientras no es usado uno cuando es construida la caché HSTS. O al revés, si el endpoint estuviera en la caché HSTS y *no* es usado el punto al final en la URL • http://www.openwall.com/lists/oss-security/2022/10/26/4 http://www.openwall.com/lists/oss-security/2022/12/21/1 https://hackerone.com/reports/1557449 https://security.gentoo.org/glsa/202212-01 https://security.netapp.com/advisory/ntap-20220609-0009 • CWE-319: Cleartext Transmission of Sensitive Information CWE-325: Missing Cryptographic Step •

libcurl wrongly allows cookies to be set for Top Level Domains (TLDs) if thehost name is provided with a trailing dot.curl can be told to receive and send cookies. curl's "cookie engine" can bebuilt with or without [Public Suffix List](https://publicsuffix.org/)awareness. If PSL support not provided, a more rudimentary check exists to atleast prevent cookies from being set on TLDs. This check was broken if thehost name in the URL uses a trailing dot.This can allow arbitrary sites to set cookies that then would get sent to adifferent and unrelated site or domain. libcurl permite erróneamente que se establezcan cookies para Dominios de Alto Nivel (TLDs) si el nombre de host es proporcionado con un punto al final. curl puede recibir y enviar cookies. "cookie engine" de curl puede construirse con o sin conocimiento de la [Lista de Sufijos Públicos] (https://publicsuffix.org/). Si no es proporcionado soporte de PSL, se presenta una comprobación más rudimentaria para al menos evitar que sean establecidas cookies en los TLD. • https://hackerone.com/reports/1553301 https://security.gentoo.org/glsa/202212-01 https://security.netapp.com/advisory/ntap-20220609-0009 • CWE-201: Insertion of Sensitive Information Into Sent Data •
