CVE-2014-2522

https://notcve.org/view.php?id=CVE-2014-2522

curl and libcurl 7.27.0 through 7.35.0, when running on Windows and using the SChannel/Winssl TLS backend, does not verify that the server hostname matches a domain name in the subject's Common Name (CN) or subjectAltName field of the X.509 certificate when accessing a URL that uses a numerical IP address, which allows man-in-the-middle attackers to spoof servers via an arbitrary valid certificate. curl y libcurl versiones 7.27.0 hasta 7.35.0, cuando se ejecuta en Windows y utiliza el backend TLS SChannel/Winssl, no comprueba que el nombre de host del servidor coincida con un nombre de dominio en el campo subject's Common Name (CN) o subjectAltName del certificado X.509 cuando se accede a una URL que usa una dirección IP numérica, que permite a los atacantes de tipo man-in-the-middle falsificar servidores por medio de un certificado válido arbitrario. • http://curl.haxx.se/docs/adv_20140326D.html http://seclists.org/oss-sec/2014/q1/585 http://seclists.org/oss-sec/2014/q1/586 http://secunia.com/advisories/57836 http://secunia.com/advisories/57966 http://secunia.com/advisories/57968 http://secunia.com/advisories/59458 http://www-947.ibm.com/support/entry/portal/docdisplay?lndocid=MIGR-5095862 http://www.getchef.com/blog/2014/04/09/chef-server-11-0-12-release http://www.getchef.com/blog/2014/04/09/enterp • CWE-20: Improper Input Validation •

CVE-2013-6422

https://notcve.org/view.php?id=CVE-2013-6422

The GnuTLS backend in libcurl 7.21.4 through 7.33.0, when disabling digital signature verification (CURLOPT_SSL_VERIFYPEER), also disables the CURLOPT_SSL_VERIFYHOST check for CN or SAN host name fields, which makes it easier for remote attackers to spoof servers and conduct man-in-the-middle (MITM) attacks. El backend de GnuTLS en libcurl 7.21.4 a 7.33.0, cuando se desactiva la verificación de firmas digitales (CURLOPT_SSL_VERIFYPEER), también desactiva la comprobación CURLOPT_SSL_VERIFYHOST para nombres de host CN o SAN, lo cual facilita a atacantes remotos la suplantación de servidores y la ejecución de ataques man-in-the-middle (MITM). • http://curl.haxx.se/docs/adv_20131217.html http://www.debian.org/security/2013/dsa-2824 http://www.oracle.com/technetwork/topics/security/cpujul2015-2367936.html http://www.ubuntu.com/usn/USN-2058-1 https://h20564.www2.hp.com/hpsc/doc/public/display?docId=emr_na-c04463322 • CWE-20: Improper Input Validation •

CVE-2013-2174 – curl: Loop counter error, leading to heap-based buffer overflow when decoding certain URLs

https://notcve.org/view.php?id=CVE-2013-2174

Heap-based buffer overflow in the curl_easy_unescape function in lib/escape.c in cURL and libcurl 7.7 through 7.30.0 allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted string ending in a "%" (percent) character. Desbordamiento de búfer basado en memoria dinámica en la función curl_easy_unescape en lib/escape.c en cURL y libcurl 7.7 a la 7.30.0, permite a atacantes remotos provocar una denegación de servicio (caída de aplicación) o posiblemente la ejecución de código arbitrario a través de una cadena manipulada que termina con el carácter "%". • http://curl.haxx.se/docs/adv_20130622.html http://lists.opensuse.org/opensuse-updates/2013-07/msg00013.html http://rhn.redhat.com/errata/RHSA-2013-0983.html http://www.debian.org/security/2013/dsa-2713 http://www.oracle.com/technetwork/topics/security/cpujul2015-2367936.html http://www.oracle.com/technetwork/topics/security/ovmbulletinjul2016-3090546.html http://www.securityfocus.com/bid/60737 http://www.ubuntu.com/usn/USN-1894-1 https://github.com/bagder/curl/commit/192c4f788d48 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-122: Heap-based Buffer Overflow •
