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-2016-8619 – curl: Double-free in krb5 code
https://notcve.org/view.php?id=CVE-2016-8619
The function `read_data()` in security.c in curl before version 7.51.0 is vulnerable to memory double free. La función "read_data()" en security.c en curl en versiones anteriores a la 7.51.0 es vulnerable a una doble liberación (double free) de memoria. • http://www.oracle.com/technetwork/security-advisory/cpuoct2018-4428296.html http://www.securityfocus.com/bid/94100 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-2016-8619 https://curl.haxx.se/CVE-2016-8619.patch https://curl.haxx.se/docs/adv_20161102E.html https://security.gentoo.org/glsa/201701-47 https://www.tenable.com/security/ • CWE-415: Double Free CWE-416: Use After Free •
CVE-2016-8620 – curl: Glob parser write/read out of bounds
https://notcve.org/view.php?id=CVE-2016-8620
The 'globbing' feature in curl before version 7.51.0 has a flaw that leads to integer overflow and out-of-bounds read via user controlled input. La funcionalidad de "globbing" en curl en versiones anteriores a la 7.51.0 tiene un error que conduce a un desbordamiento de enteros y a una lectura fuera de límites mediante entradas controladas por el usuario. • http://www.oracle.com/technetwork/security-advisory/cpuoct2018-4428296.html http://www.securityfocus.com/bid/94102 http://www.securitytracker.com/id/1037192 https://access.redhat.com/errata/RHSA-2018:3558 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2016-8620 https://curl.haxx.se/docs/adv_20161102F.html https://security.gentoo.org/glsa/201701-47 https://www.tenable.com/security/tns-2016-21 https://access.redhat.com/security/cve/CVE-2016-8620 https://bugzilla.redhat.com& • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') CWE-125: Out-of-bounds Read CWE-190: Integer Overflow or Wraparound •
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 •
CVE-2016-8618 – curl: Double-free in curl_maprintf
https://notcve.org/view.php?id=CVE-2016-8618
The libcurl API function called `curl_maprintf()` before version 7.51.0 can be tricked into doing a double-free due to an unsafe `size_t` multiplication, on systems using 32 bit `size_t` variables. La función API de libcurl llamada "curl_maprintf()" en versiones anteriores a la 7.51.0 puede ser engañada para realizar una doble liberación (double free) debido a una multiplicación "size_t" insegura en sistemas que utilizan variables "size_t" de 32 bits. • http://www.oracle.com/technetwork/security-advisory/cpuoct2018-4428296.html http://www.securityfocus.com/bid/94098 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-2016-8618 https://curl.haxx.se/docs/adv_20161102D.html https://security.gentoo.org/glsa/201701-47 https://www.tenable.com/security/tns-2016-21 https://access.redhat.com/securit • CWE-415: Double Free CWE-416: Use After Free •
