CVE-2017-2585 – keycloak: timing attack in JWS signature verification
https://notcve.org/view.php?id=CVE-2017-2585
Red Hat Keycloak before version 2.5.1 has an implementation of HMAC verification for JWS tokens that uses a method that runs in non-constant time, potentially leaving the application vulnerable to timing attacks. Red Hat Keycloak, en versiones anteriores a la 2.5.1, tiene una implementación de la verificación HMAC para los tokens JWS que emplea un método que se ejecuta en tiempo no constante, lo que podría hacer que la aplicación sea vulnerable a ataques de sincronización. It was found that keycloak's implementation of HMAC verification for JWS tokens uses a method that runs in non-constant time, potentially leaving the application vulnerable to timing attacks. • http://rhn.redhat.com/errata/RHSA-2017-0876.html http://www.securityfocus.com/bid/97393 http://www.securitytracker.com/id/1038180 https://access.redhat.com/errata/RHSA-2017:0872 https://access.redhat.com/errata/RHSA-2017:0873 https://bugzilla.redhat.com/show_bug.cgi?id=1412376 https://access.redhat.com/security/cve/CVE-2017-2585 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-385: Covert Timing Channel •
CVE-2016-8629 – keycloak: user deletion via incorrect permissions check
https://notcve.org/view.php?id=CVE-2016-8629
Red Hat Keycloak before version 2.4.0 did not correctly check permissions when handling service account user deletion requests sent to the rest server. An attacker with service account authentication could use this flaw to bypass normal permissions and delete users in a separate realm. Red Hat Keycloak, en versiones anteriores a la 2.4.0, no comprobaba correctamente los permisos al gestionar peticiones de eliminación de usuario de cuenta de servicio enviadas al servidor REST. Un atacante con autenticación de cuenta de servicio podría aprovechar este fallo para omitir permisos normales y eliminar usuarios en un realm separado. It was found that keycloak did not correctly check permissions when handling service account user deletion requests sent to the rest server. • http://rhn.redhat.com/errata/RHSA-2017-0876.html http://www.securityfocus.com/bid/97392 http://www.securitytracker.com/id/1038180 https://access.redhat.com/errata/RHSA-2017:0872 https://access.redhat.com/errata/RHSA-2017:0873 https://bugzilla.redhat.com/show_bug.cgi?id=1388988 https://access.redhat.com/security/cve/CVE-2016-8629 • CWE-264: Permissions, Privileges, and Access Controls CWE-284: Improper Access Control •
CVE-2015-0235 – Exim ESMTP 4.80 - glibc gethostbyname Denial of Service
https://notcve.org/view.php?id=CVE-2015-0235
Heap-based buffer overflow in the __nss_hostname_digits_dots function in glibc 2.2, and other 2.x versions before 2.18, allows context-dependent attackers to execute arbitrary code via vectors related to the (1) gethostbyname or (2) gethostbyname2 function, aka "GHOST." Desbordamiento de buffer basado en memoria dinámica en la función __nss_hostname_digits_dots en glibc 2.2, y otras versiones 2.x anteriores a 2.18, permite a atacantes dependientes de contexto ejecutar código arbitrario a través de vectores relacionados con la funciín (1) gethostbyname o (2) gethostbyname2, también conocido como 'GHOST.' A heap-based buffer overflow was found in glibc's __nss_hostname_digits_dots() function, which is used by the gethostbyname() and gethostbyname2() glibc function calls. A remote attacker able to make an application call either of these functions could use this flaw to execute arbitrary code with the permissions of the user running the application. The industrial managed switch series 852 from WAGO is affected by multiple vulnerabilities such as old software components embedded in the firmware. • https://www.exploit-db.com/exploits/35951 https://www.exploit-db.com/exploits/36421 https://github.com/aaronfay/CVE-2015-0235-test https://github.com/makelinux/CVE-2015-0235-workaround https://github.com/sUbc0ol/CVE-2015-0235 https://github.com/mikesplain/CVE-2015-0235-cookbook https://github.com/tobyzxj/CVE-2015-0235 https://github.com/adherzog/ansible-CVE-2015-0235-GHOST http://blogs.sophos.com/2015/01/29/sophos-products-and-the-ghost-vulnerability-affecting-linux http:/ • CWE-122: Heap-based Buffer Overflow CWE-787: Out-of-bounds Write •
