CVE-2016-8616 – curl: Case insensitive password comparison
https://notcve.org/view.php?id=CVE-2016-8616
A flaw was found in curl before version 7.51.0 When re-using a connection, curl was doing case insensitive comparisons of user name and password with the existing connections. This means that if an unused connection with proper credentials exists for a protocol that has connection-scoped credentials, an attacker can cause that connection to be reused if s/he knows the case-insensitive version of the correct password. Se ha descubierto un problema en versiones anteriores a la 7.51.0 de curl. Al reutilizar una conexión, curl realizaba comparaciones no sensibles a mayúsculas del nombre de usuario y la contraseña en las conexiones existentes. Esto significa que, si existe una conexión no utilizada con credenciales adecuadas para un protocolo que tiene credenciales restringidas a la conexión, un atacante podría provocar que se reutilice esa conexión si este conoce la versión que no distingue entre mayúsculas/minúsculas de la contraseña correcta. • http://www.oracle.com/technetwork/security-advisory/cpuoct2018-4428296.html http://www.securityfocus.com/bid/94094 http://www.securitytracker.com/id/1037192 https://access.redhat.com/errata/RHSA-2018:2486 https://access.redhat.com/errata/RHSA-2018:3558 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2016-8616 https://curl.haxx.se/CVE-2016-8616.patch https://curl.haxx.se/docs/adv_20161102B.html https://security.gentoo.org/glsa/201701-47 https://www.tenable.com/security/ • CWE-255: Credentials Management Errors CWE-287: Improper Authentication CWE-592: DEPRECATED: Authentication Bypass Issues •

CVE-2016-8623 – curl: Use-after-free via shared cookies
https://notcve.org/view.php?id=CVE-2016-8623
A flaw was found in curl before version 7.51.0. The way curl handles cookies permits other threads to trigger a use-after-free leading to information disclosure. Se ha descubierto un problema en versiones anteriores a la 7.51.0 de curl. La forma en la que curl gestiona las cookies permite que otros hilos desencadenen un uso de memoria previamente liberada que conduce a una divulgación de información. • http://www.oracle.com/technetwork/security-advisory/cpuoct2018-4428296.html http://www.securityfocus.com/bid/94106 http://www.securitytracker.com/id/1037192 https://access.redhat.com/errata/RHSA-2018:2486 https://access.redhat.com/errata/RHSA-2018:3558 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2016-8623 https://curl.haxx.se/CVE-2016-8623.patch https://curl.haxx.se/docs/adv_20161102I.html https://lists.apache.org/thread.html/r58af02e294bd07f487e2c64ffc0a29b837db5600e33b6e698b9d696b%40%3Cissu • CWE-416: Use After Free •
