https://notcve.org/view.php?id=CVE-2019-14896
A heap-based buffer overflow vulnerability was found in the Linux kernel, version kernel-2.6.32, in Marvell WiFi chip driver. A remote attacker could cause a denial of service (system crash) or, possibly execute arbitrary code, when the lbs_ibss_join_existing function is called after a STA connects to an AP. Se encontró una vulnerabilidad de desbordamiento de búfer basada en el montón en el kernel de Linux, versión kernel-2.6.32, en el controlador de chip WiFi Marvell. Un atacante remoto podría causar una denegación de servicio (bloqueo del sistema) o, posiblemente, ejecutar código arbitrario, cuando se llama a la función lbs_ibss_join_existing después de que una STA se conecta a un AP. A heap-based buffer overflow vulnerability was found in the Linux kernel's Marvell WiFi chip driver. • http://lists.opensuse.org/opensuse-security-announce/2020-03/msg00021.html http://packetstormsecurity.com/files/155879/Kernel-Live-Patch-Security-Notice-LSN-0061-1.html http://packetstormsecurity.com/files/156185/Kernel-Live-Patch-Security-Notice-LSN-0062-1.html https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2019-14896 https://lists.debian.org/debian-lts-announce/2020/01/msg00013.html https://lists.debian.org/debian-lts-announce/2020/03/msg00001.html https://lists.fedoraproject.org/archives/list& • CWE-122: Heap-based Buffer Overflow CWE-787: Out-of-bounds Write •

Ruby through 2.4.7, 2.5.x through 2.5.6, and 2.6.x through 2.6.4 mishandles path checking within File.fnmatch functions. Ruby versiones hasta 2.4.7, versiones 2.5.x hasta 2.5.6 y versiones 2.6.x hasta 2.6.4, maneja inapropiadamente la comprobación de ruta dentro de las funciones File.fnmatch. A flaw was discovered in Ruby in the way certain functions handled strings containing NULL bytes. Specifically, the built-in methods File.fnmatch and its alias File.fnmatch? did not properly handle path patterns containing the NULL byte. • http://lists.opensuse.org/opensuse-security-announce/2020-03/msg00041.html https://hackerone.com/reports/449617 https://lists.debian.org/debian-lts-announce/2019/11/msg00025.html https://seclists.org/bugtraq/2019/Dec/31 https://seclists.org/bugtraq/2019/Dec/32 https://security.gentoo.org/glsa/202003-06 https://usn.ubuntu.com/4201-1 https://www.debian.org/security/2019/dsa-4587 https://www.oracle.com/security-alerts/cpujan2020.html https://access.redhat.com/security/cve • CWE-41: Improper Resolution of Path Equivalence •

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 •
CVSS: 9.1EPSS: 0%CPEs: 13EXPL: 0CVE-2019-12523 – squid: Improper input validation in URI processor
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 •
