CVSS: 7.5EPSS: 0%CPEs: 9EXPL: 0CVE-2020-8449 – squid: Improper input validation issues in HTTP Request processing
https://notcve.org/view.php?id=CVE-2020-8449
An issue was discovered in Squid before 4.10. Due to incorrect input validation, it can interpret crafted HTTP requests in unexpected ways to access server resources prohibited by earlier security filters. Se detectó un problema en Squid versiones anteriores a 4.10. Debido a una comprobación de entrada incorrecta, puede interpretar las peticiones HTTP diseñadas de manera no prevista para acceder a recursos del servidor prohibidos por parte de los filtros de seguridad anteriores. A flaw was found in squid. • http://lists.opensuse.org/opensuse-security-announce/2020-03/msg00012.html http://lists.opensuse.org/opensuse-security-announce/2020-05/msg00010.html http://www.squid-cache.org/Advisories/SQUID-2020_1.txt http://www.squid-cache.org/Versions/v3/3.5/changesets/SQUID-2020_1.patch http://www.squid-cache.org/Versions/v3/3.5/changesets/squid-3.5-8e657e835965c3a011375feaa0359921c5b3e2dd.patch http://www.squid-cache.org/Versions/v4/changesets/SQUID-2020_1.patch http://www.squid-cache.org/Versions&# • CWE-20: Improper Input Validation CWE-668: Exposure of Resource to Wrong Sphere •
CVSS: 9.8EPSS: 3%CPEs: 12EXPL: 0CVE-2019-12526 – squid: Heap overflow issue in URN processing
https://notcve.org/view.php?id=CVE-2019-12526
An issue was discovered in Squid before 4.9. URN response handling in Squid suffers from a heap-based buffer overflow. When receiving data from a remote server in response to an URN request, Squid fails to ensure that the response can fit within the buffer. This leads to attacker controlled data overflowing in the heap. Se detectó un problema en Squid versiones anteriores a 4.9. • http://www.squid-cache.org/Advisories/SQUID-2019_7.txt https://bugzilla.suse.com/show_bug.cgi?id=1156326 https://lists.debian.org/debian-lts-announce/2019/12/msg00011.html https://lists.debian.org/debian-lts-announce/2020/07/msg00009.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/MTM74TU2BSLT5B3H4F3UDW53672NVLMC https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/UEMOYTMCCFWK5NOXSXEIH5D2VGWVXR67 https://security.gentoo.org&#x • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-787: Out-of-bounds Write •

https://notcve.org/view.php?id=CVE-2019-12523
An issue was discovered in Squid before 4.9. When handling a URN request, a corresponding HTTP request is made. This HTTP request doesn't go through the access checks that incoming HTTP requests go through. This causes all access checks to be bypassed and allows access to restricted HTTP servers, e.g., an attacker can connect to HTTP servers that only listen on localhost. Se detectó un problema en Squid versiones anteriores a 4.9. • http://lists.opensuse.org/opensuse-security-announce/2019-11/msg00056.html http://www.squid-cache.org/Advisories/SQUID-2019_8.txt https://bugzilla.suse.com/show_bug.cgi?id=1156329 https://lists.debian.org/debian-lts-announce/2020/07/msg00009.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/MTM74TU2BSLT5B3H4F3UDW53672NVLMC https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/UEMOYTMCCFWK5NOXSXEIH5D2VGWVXR67 https://usn.ubuntu.com& • CWE-20: Improper Input Validation •

https://notcve.org/view.php?id=CVE-2019-18676
An issue was discovered in Squid 3.x and 4.x through 4.8. Due to incorrect input validation, there is a heap-based buffer overflow that can result in Denial of Service to all clients using the proxy. Severity is high due to this vulnerability occurring before normal security checks; any remote client that can reach the proxy port can trivially perform the attack via a crafted URI scheme. Se descubrió un problema en Squid versiones 2.x, 3.x y versiones 4.x hasta 4.8. Debido a una comprobación de entrada incorrecta, hay un desbordamiento del búfer en la región heap de la memoria que puede resultar en una Denegación de Servicio a todos los clientes que usan el proxy. • http://www.squid-cache.org/Advisories/SQUID-2019_8.txt http://www.squid-cache.org/Versions/v4/changesets/squid-4-fbbdf75efd7a5cc244b4886a9d42ea458c5a3a73.patch https://bugzilla.suse.com/show_bug.cgi?id=1156329 https://github.com/squid-cache/squid/pull/275 https://lists.debian.org/debian-lts-announce/2020/07/msg00009.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/MTM74TU2BSLT5B3H4F3UDW53672NVLMC https://lists.fedoraproject.org/archives/list/package-announce%40lists • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-787: Out-of-bounds Write •

An issue was discovered in Squid 3.x and 4.x through 4.8 when the append_domain setting is used (because the appended characters do not properly interact with hostname length restrictions). Due to incorrect message processing, it can inappropriately redirect traffic to origins it should not be delivered to. Se descubrió un problema en Squid versiones 2.x, 3.x y versiones 4.x hasta 4.8 cuando la configuración append_domain es usada (porque los caracteres añadidos no interactúan apropiadamente con las restricciones de longitud del nombre de host). Debido a un procesamiento incorrecto del mensaje, puede redireccionar inapropiadamente el tráfico a los orígenes a los que no debe ser enviado. • http://www.squid-cache.org/Advisories/SQUID-2019_9.txt http://www.squid-cache.org/Versions/v3/3.5/changesets/squid-3.5-e5f1813a674848dde570f7920873e1071f96e0b4.patch http://www.squid-cache.org/Versions/v4/changesets/squid-4-36492033ea4097821a4f7ff3ddcb971fbd1e8ba0.patch https://bugzilla.suse.com/show_bug.cgi?id=1156328 https://github.com/squid-cache/squid/pull/427 https://lists.debian.org/debian-lts-announce/2019/12/msg00011.html https://lists.debian.org/debian-lts-announce/2020/07/msg00009.html h • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') CWE-352: Cross-Site Request Forgery (CSRF) •
