CVE-2018-1000121 – curl: LDAP NULL pointer dereference

https://notcve.org/view.php?id=CVE-2018-1000121

A NULL pointer dereference exists in curl 7.21.0 to and including curl 7.58.0 in the LDAP code that allows an attacker to cause a denial of service Existe una desreferencia de puntero NULL en curl, de la versión 7.21.0 a la 7.58.0, en el código LDAP que permite que un atacante provoque una denegación de servicio (DoS). A NULL pointer dereference flaw was found in the way libcurl checks values returned by the openldap ldap_get_attribute_ber() function. A malicious LDAP server could use this flaw to crash a libcurl client application via a specially crafted LDAP reply. • http://www.oracle.com/technetwork/security-advisory/cpujul2018-4258247.html http://www.oracle.com/technetwork/security-advisory/cpuoct2018-4428296.html http://www.securityfocus.com/bid/103415 http://www.securitytracker.com/id/1040529 https://access.redhat.com/errata/RHBA-2019:0327 https://access.redhat.com/errata/RHSA-2018:3157 https://access.redhat.com/errata/RHSA-2018:3558 https://access.redhat.com/errata/RHSA-2020:0544 https://access.redhat.com/errata/RHSA-2020:0594 https://curl&# • CWE-476: NULL Pointer Dereference •

CVE-2018-1000007 – curl: HTTP authentication leak in redirects

https://notcve.org/view.php?id=CVE-2018-1000007

libcurl 7.1 through 7.57.0 might accidentally leak authentication data to third parties. When asked to send custom headers in its HTTP requests, libcurl will send that set of headers first to the host in the initial URL but also, if asked to follow redirects and a 30X HTTP response code is returned, to the host mentioned in URL in the `Location:` response header value. Sending the same set of headers to subsequent hosts is in particular a problem for applications that pass on custom `Authorization:` headers, as this header often contains privacy sensitive information or data that could allow others to impersonate the libcurl-using client's request. libcurl, desde la versión 7.1 hasta la 7.57.0, podría filtrar accidentalmente datos de autenticación a terceros. Cuando se le solicita que envíe cabeceras personalizadas en sus peticiones HTTP, libcurl enviará primero ese conjunto de cabeceras al host en la URL inicial pero también, si se le pide que siga redirecciones y se devuelve un código de respuesta HTTP 30X al host mencionado en la URL en el valor de la cabecera de respuesta "Location:". El envío de la misma serie de cabeceras a hosts subsecuentes es un problema en particular para las aplicaciones que pasan cabeceras "Authorization:" personalizadas, ya que esta cabecera suele contener información sensible de privacidad o datos que podrían permitir que otros suplanten la petición del cliente que emplea libcurl. • http://www.openwall.com/lists/oss-security/2022/04/27/4 http://www.securitytracker.com/id/1040274 https://access.redhat.com/errata/RHBA-2019:0327 https://access.redhat.com/errata/RHSA-2018:3157 https://access.redhat.com/errata/RHSA-2018:3558 https://access.redhat.com/errata/RHSA-2019:1543 https://access.redhat.com/errata/RHSA-2020:0544 https://access.redhat.com/errata/RHSA-2020:0594 https://curl.haxx.se/docs/adv_2018-b3bf.html https://lists.debian.org/debian • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

CVE-2017-8818

https://notcve.org/view.php?id=CVE-2017-8818

curl and libcurl before 7.57.0 on 32-bit platforms allow attackers to cause a denial of service (out-of-bounds access and application crash) or possibly have unspecified other impact because too little memory is allocated for interfacing to an SSL library. curl y libcurl en versiones anteriores a la 7.57.0 en plataformas de 32 bits permiten que los atacantes provoquen una denegación de servicio (acceso fuera de límites y cierre inesperado de la aplicación) o, posiblemente, provoquen otro impacto porque se asigna demasiado poca memoria para interconectarse con una librería SSL. • http://security.cucumberlinux.com/security/details.php?id=163 http://www.securityfocus.com/bid/102014 http://www.securitytracker.com/id/1039898 https://curl.haxx.se/docs/adv_2017-af0a.html https://security.gentoo.org/glsa/201712-04 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

CVE-2017-8816 – curl: NTLM buffer overflow via integer overflow

https://notcve.org/view.php?id=CVE-2017-8816

The NTLM authentication feature in curl and libcurl before 7.57.0 on 32-bit platforms allows attackers to cause a denial of service (integer overflow and resultant buffer overflow, and application crash) or possibly have unspecified other impact via vectors involving long user and password fields. La característica de autenticación NTLM en curl y libcurl en versiones anteriores a la 7.57.0 en plataformas de 32-bits permite que los atacantes provoquen una denegación de servicio (desbordamiento de enteros y desbordamiento de búfer resultante, y cierre inesperado de la aplicación) o que, posiblemente, causen otro tipo de impacto sin especificar mediante vectores relacionados con campos user y password largos. • http://security.cucumberlinux.com/security/details.php?id=161 http://www.securityfocus.com/bid/101998 http://www.securitytracker.com/id/1039896 http://www.securitytracker.com/id/1040608 https://access.redhat.com/errata/RHSA-2018:3558 https://curl.haxx.se/docs/adv_2017-12e7.html https://security.gentoo.org/glsa/201712-04 https://www.debian.org/security/2017/dsa-4051 https://access.redhat.com/security/cve/CVE-2017-8816 https://bugzilla.redhat.com/show_bug.cgi?id=1515757 • CWE-122: Heap-based Buffer Overflow CWE-190: Integer Overflow or Wraparound •
