https://notcve.org/view.php?id=CVE-2018-16842
Curl versions 7.14.1 through 7.61.1 are vulnerable to a heap-based buffer over-read in the tool_msgs.c:voutf() function that may result in information exposure and denial of service. Curl, desde la versión 7.14.1 hasta la 7.61.1, es vulnerable a una sobrelectura de búfer basada en memoria dinámica (heap) en la función tool_msgs.c:voutf() que podría resultar en una exposición de información y una denegación de servicio (DoS). • http://www.securitytracker.com/id/1042014 https://access.redhat.com/errata/RHSA-2019:2181 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2018-16842 https://curl.haxx.se/docs/CVE-2018-16842.html https://github.com/curl/curl/commit/d530e92f59ae9bb2d47066c3c460b25d2ffeb211 https://lists.debian.org/debian-lts-announce/2018/11/msg00005.html https://security.gentoo.org/glsa/201903-03 https://usn.ubuntu.com/3805-1 https://usn.ubuntu.com/3805-2 https://www.debian.org/security/2 • CWE-125: Out-of-bounds Read •
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 •
