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 •

CVSS: 9.8EPSS: 1%CPEs: 3EXPL: 1CVE-2018-0500 – curl: Heap-based buffer overflow in Curl_smtp_escape_eob() when uploading data over SMTP
https://notcve.org/view.php?id=CVE-2018-0500
Curl_smtp_escape_eob in lib/smtp.c in curl 7.54.1 to and including curl 7.60.0 has a heap-based buffer overflow that might be exploitable by an attacker who can control the data that curl transmits over SMTP with certain settings (i.e., use of a nonstandard --limit-rate argument or CURLOPT_BUFFERSIZE value). Curl_smtp_escape_eob en lib/smtp.c en curl desde la versión 7.54.1 hasta la 7.60.0 tiene un desbordamiento de búfer basado en memoria dinámica (heap) que podría ser explotado por un atacante que pueda controlar los datos que curl transmite por SMTP con ciertas opciones (p.ej., el uso de un argumento no estándar --limit-rate o un valor CURLOPT_BUFFERSIZE). A heap-based buffer overflow has been found in the Curl_smtp_escape_eob() function of curl. An attacker could exploit this by convincing a user to use curl to upload data over SMTP with a reduced buffer to cause a crash or corrupt memory. • http://www.securitytracker.com/id/1041280 https://access.redhat.com/errata/RHSA-2018:2486 https://curl.haxx.se/docs/adv_2018-70a2.html https://github.com/curl/curl/commit/ba1dbd78e5f1ed67c1b8d37ac89d90e5e330b628 https://security.gentoo.org/glsa/201807-04 https://usn.ubuntu.com/3710-1 https://access.redhat.com/security/cve/CVE-2018-0500 https://bugzilla.redhat.com/show_bug.cgi?id=1597101 • CWE-122: Heap-based Buffer Overflow CWE-787: Out-of-bounds Write •
