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 •

The FTP wildcard function in curl and libcurl before 7.57.0 allows remote attackers to cause a denial of service (out-of-bounds read and application crash) or possibly have unspecified other impact via a string that ends with an '[' character. La función FTP wildcard en curl y libcurl en versiones anteriores a la 7.57.0 permite que atacantes remotos provoquen una denegación de servicio (lectura fuera de límites y cierre inesperado de aplicación) o, probablemente, causen cualquier otro tipo de impacto mediante una cadena que termina con un carácter "[". • http://security.cucumberlinux.com/security/details.php?id=162 http://www.securityfocus.com/bid/102057 http://www.securitytracker.com/id/1039897 https://access.redhat.com/errata/RHSA-2018:3558 https://curl.haxx.se/docs/adv_2017-ae72.html https://lists.debian.org/debian-lts-announce/2017/11/msg00040.html https://security.gentoo.org/glsa/201712-04 https://www.debian.org/security/2017/dsa-4051 https://access.redhat.com/security/cve/CVE-2017-8817 https://bugzilla.redhat.com& • CWE-125: Out-of-bounds Read •
CVSS: 6.5EPSS: 0%CPEs: 32EXPL: 0CVE-2017-1000101 – curl: URL globbing out of bounds read
https://notcve.org/view.php?id=CVE-2017-1000101
curl supports "globbing" of URLs, in which a user can pass a numerical range to have the tool iterate over those numbers to do a sequence of transfers. In the globbing function that parses the numerical range, there was an omission that made curl read a byte beyond the end of the URL if given a carefully crafted, or just wrongly written, URL. The URL is stored in a heap based buffer, so it could then be made to wrongly read something else instead of crashing. An example of a URL that triggers the flaw would be `http://ur%20[0-60000000000000000000`. curl es compatible con el "globbing" de URL, donde un usuario puede pasar un rango numérico para hacer que la herramienta itere sobre esos números para realizar una secuencia de transferencias. En la función de "globbing" que analiza sintácticamente el rango numérico, hay una omisión que hace que curl lea un byte más allá del fin de la URL si se proporciona una URL manipulada o simplemente mal escrita. • http://www.debian.org/security/2017/dsa-3992 http://www.securityfocus.com/bid/100249 http://www.securitytracker.com/id/1039117 https://access.redhat.com/errata/RHSA-2018:3558 https://curl.haxx.se/docs/adv_20170809A.html https://security.gentoo.org/glsa/201709-14 https://support.apple.com/HT208221 https://access.redhat.com/security/cve/CVE-2017-1000101 https://bugzilla.redhat.com/show_bug.cgi?id=1478309 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-125: Out-of-bounds Read •
CVSS: 5.3EPSS: 0%CPEs: 1EXPL: 0CVE-2017-9502
https://notcve.org/view.php?id=CVE-2017-9502
In curl before 7.54.1 on Windows and DOS, libcurl's default protocol function, which is the logic that allows an application to set which protocol libcurl should attempt to use when given a URL without a scheme part, had a flaw that could lead to it overwriting a heap based memory buffer with seven bytes. If the default protocol is specified to be FILE or a file: URL lacks two slashes, the given "URL" starts with a drive letter, and libcurl is built for Windows or DOS, then libcurl would copy the path 7 bytes off, so that the end of the given path would write beyond the malloc buffer (7 bytes being the length in bytes of the ascii string "file://"). En curl en sus versiones anteriores a la 7.54.1 de Windows y DOS, la función libcurl de protocolo por defecto, el cual es lógico que permita una aplicación poner que protocolo libcurl debe intentar usar cuando una URL le es dada sin una parte diseñada, tiene un flaw que podría llevar a sobrescribir buffer heap --heap-- con siete bytes. Si se especifica que el protocolo sea FILE o un archivo: A la URL le faltan dos barras, la URL dada comienza con una letra de unidad, y libcurl es construida para Windows o DOS, entonces libcurl copiaría la ruta de 7bytes, asique el final de la ruta dada escribiría mas allá del buffer reservado (7 bytes son la longitud de la cadena ASCII "file://"). • http://openwall.com/lists/oss-security/2017/06/14/1 http://www.securityfocus.com/bid/99120 http://www.securitytracker.com/id/1038697 https://curl.haxx.se/docs/adv_20170614.html • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

https://notcve.org/view.php?id=CVE-2017-2628
curl, as shipped in Red Hat Enterprise Linux 6 before version 7.19.7-53, did not correctly backport the fix for CVE-2015-3148 because it did not reflect the fact that the HAVE_GSSAPI define was meanwhile substituted by USE_HTTP_NEGOTIATE. This issue was introduced in RHEL 6.7 and affects RHEL 6 curl only. curl, tal y como se distribuye en Red Hat Enterprise Linux 6, en versiones anteriores a la 7.19.7-53, no realizó correctamente el backport de la solución para CVE-2015-3148 debido a que no reflejó el hecho de que la definición HAVE_GSSAPI se sustituyó mientras tanto por USE_HTTP_NEGOTIATE. Este problema se introdujo en RHEL 6.7 y solo afecta a RHEL 6 curl. It was found that the fix for CVE-2015-3148 in curl was incomplete. An application using libcurl with HTTP Negotiate authentication could incorrectly re-use credentials for subsequent requests to the same server. • http://rhn.redhat.com/errata/RHSA-2017-0847.html http://www.securityfocus.com/bid/97187 https://bugzilla.redhat.com/show_bug.cgi?id=1422464 https://access.redhat.com/security/cve/CVE-2017-2628 • CWE-287: Improper Authentication •
