CVSS: 9.8EPSS: 0%CPEs: 5EXPL: 0CVE-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 •

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 •
