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. This issue occurs because it mishandles message verification failures when curl does FTP transfers secured by krb5. • http://seclists.org/fulldisclosure/2022/Oct/28 http://seclists.org/fulldisclosure/2022/Oct/41 https://hackerone.com/reports/1590071 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://security.netapp.com/advisory/ntap-20220915-0003 https://support.apple.com/kb/HT213488 https://www.debian.org/security/2022/ • CWE-787: Out-of-bounds Write CWE-840: Business Logic Errors CWE-924: Improper Enforcement of Message Integrity During Transmission in a Communication Channel •

https://notcve.org/view.php?id=CVE-2022-27775
An information disclosure vulnerability exists in curl 7.65.0 to 7.82.0 are vulnerable that by using an IPv6 address that was in the connection pool but with a different zone id it could reuse a connection instead. Se presenta una vulnerabilidad de divulgación de información en curl versiones 7.65.0 a 7.82.0, son vulnerables que al usar una dirección IPv6 que estaba en el pool de conexiones pero con un id de zona diferente podría reusar una conexión en su lugar A vulnerability was found in curl. This security flaw occurs due to errors in the logic where the config matching function did not take the IPv6 address zone id into account. This issue can lead to curl reusing the wrong connection when one transfer uses a zone id, and the subsequent transfer uses another. • https://hackerone.com/reports/1546268 https://security.gentoo.org/glsa/202212-01 https://security.netapp.com/advisory/ntap-20220609-0008 https://www.debian.org/security/2022/dsa-5197 https://access.redhat.com/security/cve/CVE-2022-27775 https://bugzilla.redhat.com/show_bug.cgi?id=2078388 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
