CVSS: 9.8EPSS: 0%CPEs: 17EXPL: 0CVE-2018-1000120 – curl: FTP path trickery leads to NIL byte out of bounds write
https://notcve.org/view.php?id=CVE-2018-1000120
A buffer overflow exists in curl 7.12.3 to and including curl 7.58.0 in the FTP URL handling that allows an attacker to cause a denial of service or worse. Existe un desbordamiento de búfer en curl, de la versión 7.12.3 a la 7.58.0, en la gestión de URL FTP que permite que un atacante provoque una denegación de servicio (DoS) o algo peor. It was found that libcurl did not safely parse FTP URLs when using the CURLOPT_FTP_FILEMETHOD method. An attacker, able to provide a specially crafted FTP URL to an application using libcurl, could write a NULL byte at an arbitrary location, resulting in a crash or an unspecified behavior. • http://www.oracle.com/technetwork/security-advisory/cpujul2018-4258247.html http://www.oracle.com/technetwork/security-advisory/cpuoct2018-4428296.html http://www.securityfocus.com/bid/103414 http://www.securitytracker.com/id/1040531 https://access.redhat.com/errata/RHBA-2019:0327 https://access.redhat.com/errata/RHSA-2018:3157 https://access.redhat.com/errata/RHSA-2018:3558 https://access.redhat.com/errata/RHSA-2019:1543 https://access.redhat.com/errata/RHSA-2020:0544 https://access • CWE-787: Out-of-bounds Write •

https://notcve.org/view.php?id=CVE-2018-1000121
A NULL pointer dereference exists in curl 7.21.0 to and including curl 7.58.0 in the LDAP code that allows an attacker to cause a denial of service Existe una desreferencia de puntero NULL en curl, de la versión 7.21.0 a la 7.58.0, en el código LDAP que permite que un atacante provoque una denegación de servicio (DoS). A NULL pointer dereference flaw was found in the way libcurl checks values returned by the openldap ldap_get_attribute_ber() function. A malicious LDAP server could use this flaw to crash a libcurl client application via a specially crafted LDAP reply. • http://www.oracle.com/technetwork/security-advisory/cpujul2018-4258247.html http://www.oracle.com/technetwork/security-advisory/cpuoct2018-4428296.html http://www.securityfocus.com/bid/103415 http://www.securitytracker.com/id/1040529 https://access.redhat.com/errata/RHBA-2019:0327 https://access.redhat.com/errata/RHSA-2018:3157 https://access.redhat.com/errata/RHSA-2018:3558 https://access.redhat.com/errata/RHSA-2020:0544 https://access.redhat.com/errata/RHSA-2020:0594 https://curl&# • CWE-476: NULL Pointer Dereference •

https://notcve.org/view.php?id=CVE-2016-9953
The verify_certificate function in lib/vtls/schannel.c in libcurl 7.30.0 through 7.51.0, when built for Windows CE using the schannel TLS backend, allows remote attackers to obtain sensitive information, cause a denial of service (crash), or possibly have unspecified other impact via a wildcard certificate name, which triggers an out-of-bounds read. La función verify_certificate en lib/vtls/schannel.c en libcurl, desde la versión 7.30.0 hasta la 7.51.0, cuando se construye para Windows CE usando el backend TLS schannel, permite a los atacantes remotos obtener información sensible, causar una denegación de servicio (cierre inesperado) o, posiblemente, tener otro tipo de impacto no especificado mediante un nombre de certificado wildcard, lo cual desencadena una lectura fuera de límites. • https://curl.haxx.se/CVE-2016-9952.patch https://curl.haxx.se/docs/adv_20161221C.html • CWE-125: Out-of-bounds Read •

The verify_certificate function in lib/vtls/schannel.c in libcurl 7.30.0 through 7.51.0, when built for Windows CE using the schannel TLS backend, makes it easier for remote attackers to conduct man-in-the-middle attacks via a crafted wildcard SAN in a server certificate, as demonstrated by "*.com." La función verify_certificate en lib/vtls/schannel.c en libcurl, desde la versión 7.30.0 hasta la 7.51.0, cuando se construye para Windows CE usando el backend TLS schannel, facilita la ejecución de ataques Man-in-the-Middle (MitM) por parte de atacantes remotos mediante un wildcard SAN manipulado en un certificado de servidor, tal y como demuestra "*.com". • https://curl.haxx.se/CVE-2016-9952.patch https://curl.haxx.se/docs/adv_20161221B.html • CWE-295: Improper Certificate Validation •
