CVE-2019-5443
https://notcve.org/view.php?id=CVE-2019-5443
A non-privileged user or program can put code and a config file in a known non-privileged path (under C:/usr/local/) that will make curl <= 7.65.1 automatically run the code (as an openssl "engine") on invocation. If that curl is invoked by a privileged user it can do anything it wants. Un usuario o programa no privilegiado puede colocar un código y un archivo de configuración en una ruta (path) no privilegiada conocida (bajo C:/usr/local/) que hará que curl anterior a versión 7.65.1 incluyéndola, ejecute automáticamente el código en la invocación (como un "engine" openssl). Si ese curl es invocado por un usuario privilegiado, este puede hacer lo que desee. • http://www.openwall.com/lists/oss-security/2019/06/24/1 http://www.securityfocus.com/bid/108881 https://curl.haxx.se/docs/CVE-2019-5443.html https://security.netapp.com/advisory/ntap-20191017-0002 https://www.oracle.com/security-alerts/cpuapr2020.html https://www.oracle.com/security-alerts/cpuoct2020.html https://www.oracle.com/technetwork/security-advisory/cpuoct2019-5072832.html • CWE-94: Improper Control of Generation of Code ('Code Injection') CWE-427: Uncontrolled Search Path Element •
CVE-2019-5435 – curl: Integer overflows in curl_url_set() function
https://notcve.org/view.php?id=CVE-2019-5435
An integer overflow in curl's URL API results in a buffer overflow in libcurl 7.62.0 to and including 7.64.1. Un desbordamiento de enteros en la API de URL de curl, da como resultado un desbordamiento de búfer en libcurl en la versión 7.62.0 hasta la 7.64.1 incluyendola. • https://curl.haxx.se/docs/CVE-2019-5435.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/SMG3V4VTX2SE3EW3HQTN3DDLQBTORQC2 https://security.gentoo.org/glsa/202003-29 https://security.netapp.com/advisory/ntap-20190606-0004 https://support.f5.com/csp/article/K08125515 https://www.oracle.com/security-alerts/cpuapr2020.html https://www.oracle.com/security-alerts/cpuoct2020.html https://www.oracle.com/technetwork/security-advisory/cpuoct2019-5072832.html https: • CWE-131: Incorrect Calculation of Buffer Size CWE-190: Integer Overflow or Wraparound •
CVE-2018-16840 – curl: Use-after-free when closing "easy" handle in Curl_close()
https://notcve.org/view.php?id=CVE-2018-16840
A heap use-after-free flaw was found in curl versions from 7.59.0 through 7.61.1 in the code related to closing an easy handle. When closing and cleaning up an 'easy' handle in the `Curl_close()` function, the library code first frees a struct (without nulling the pointer) and might then subsequently erroneously write to a struct field within that already freed struct. Se ha detectado un error de uso de memoria dinámica (heap) previamente liberada en Curl, desde la versión 7.59.0 hasta la 7.61.1, en el código relacionado con el cierre de un controlador "easy". Al cerrar y limpiar un controlador "easy" en la función "Curl_close()", el código de la biblioteca libera, en primer lugar, un struct (sin pasar el puntero a null) y, después, podría escribir erróneamente en un campo struct dentro del struct ya liberado. • http://www.securitytracker.com/id/1042013 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2018-16840 https://curl.haxx.se/docs/CVE-2018-16840.html https://github.com/curl/curl/commit/81d135d67155c5295b1033679c606165d4e28f3f https://security.gentoo.org/glsa/201903-03 https://usn.ubuntu.com/3805-1 https://access.redhat.com/security/cve/CVE-2018-16840 https://bugzilla.redhat.com/show_bug.cgi?id=1642203 • CWE-416: Use After Free •
