CVE-2015-5739 – golang: HTTP request smuggling in net/http library
https://notcve.org/view.php?id=CVE-2015-5739
The net/http library in net/textproto/reader.go in Go before 1.4.3 does not properly parse HTTP header keys, which allows remote attackers to conduct HTTP request smuggling attacks via a space instead of a hyphen, as demonstrated by "Content Length" instead of "Content-Length." La biblioteca net/http en net/textproto/reader.go en Go en versiones anteriores a la 1.4.3 no analiza sintácticamente claves de cabecera HTTP correctamente, lo que permite que atacantes remotos lleven a cabo ataques de contrabando de peticiones HTTP mediante un espacio en lugar de un guión, tal y como se muestra en "Content Length", en lugar de "Content-Length". HTTP-request vulnerabilities have been found in the Golang net/http and net/textproto libraries. Request headers with double Content-Length fields do not generate a 400 error (the second field is ignored), and invalid fields are parsed as valid (for example, "Content Length:" with a space in the middle is accepted). A non-authenticated attacker could exploit these flaws to bypass security controls, perform web-cache poisoning, or alter the request/response map (denial of service). • http://lists.fedoraproject.org/pipermail/package-announce/2015-October/167997.html http://lists.fedoraproject.org/pipermail/package-announce/2015-October/168029.html http://rhn.redhat.com/errata/RHSA-2016-1538.html http://seclists.org/oss-sec/2015/q3/237 http://seclists.org/oss-sec/2015/q3/292 http://seclists.org/oss-sec/2015/q3/294 http://www.securityfocus.com/bid/76281 https://bugzilla.redhat.com/show_bug.cgi?id=1250352 https://github.com/golang/go/commit/117ddcb83d7f42d • CWE-444: Inconsistent Interpretation of HTTP Requests ('HTTP Request/Response Smuggling') •
CVE-2017-0903 – rubygems: Unsafe object deserialization through YAML formatted gem specifications
https://notcve.org/view.php?id=CVE-2017-0903
RubyGems versions between 2.0.0 and 2.6.13 are vulnerable to a possible remote code execution vulnerability. YAML deserialization of gem specifications can bypass class white lists. Specially crafted serialized objects can possibly be used to escalate to remote code execution. Las versiones de RubyGems entre la 2.0.0 y la 2.6.13 son vulnerables a una posible vulnerabilidad de ejecución remota de código. La deserialización YAML de especificaciones de gemas puede omitir listas blancas de clases. • http://blog.rubygems.org/2017/10/09/2.6.14-released.html http://blog.rubygems.org/2017/10/09/unsafe-object-deserialization-vulnerability.html http://www.securityfocus.com/bid/101275 https://access.redhat.com/errata/RHSA-2017:3485 https://access.redhat.com/errata/RHSA-2018:0378 https://access.redhat.com/errata/RHSA-2018:0583 https://access.redhat.com/errata/RHSA-2018:0585 https://github.com/rubygems/rubygems/commit/510b1638ac9bba3ceb7a5d73135dafff9e5bab49 https://hackerone.com/reports/27499 • CWE-20: Improper Input Validation CWE-502: Deserialization of Untrusted Data •
CVE-2017-7819 – Mozilla: Use-after-free while resizing images in design mode (MFSA 2017-22)
https://notcve.org/view.php?id=CVE-2017-7819
A use-after-free vulnerability can occur in design mode when image objects are resized if objects referenced during the resizing have been freed from memory. This results in a potentially exploitable crash. This vulnerability affects Firefox < 56, Firefox ESR < 52.4, and Thunderbird < 52.4. Puede ocurrir una vulnerabilidad de uso de memoria previamente liberada cuando los objetos imagen se redimensionan si los objetos referenciados durante el redimensionamiento se han liberado de la memoria. Esto resulta en un cierre inesperado explotable. • http://www.securityfocus.com/bid/101055 http://www.securitytracker.com/id/1039465 https://access.redhat.com/errata/RHSA-2017:2831 https://access.redhat.com/errata/RHSA-2017:2885 https://bugzilla.mozilla.org/show_bug.cgi?id=1380292 https://lists.debian.org/debian-lts-announce/2017/11/msg00000.html https://security.gentoo.org/glsa/201803-14 https://www.debian.org/security/2017/dsa-3987 https://www.debian.org/security/2017/dsa-4014 https://www.mozilla.org/security/advisor • CWE-416: Use After Free •
CVE-2017-7810 – Mozilla: Memory safety bugs fixed in Firefox 56 and Firefox ESR 52.4 (MFSA 2017-22)
https://notcve.org/view.php?id=CVE-2017-7810
Memory safety bugs were reported in Firefox 55 and Firefox ESR 52.3. Some of these bugs showed evidence of memory corruption and we presume that with enough effort that some of these could be exploited to run arbitrary code. This vulnerability affects Firefox < 56, Firefox ESR < 52.4, and Thunderbird < 52.4. Se han informado de errores de seguridad de memoria en Firefox 55 y Firefox ESR 52.3.

CVE-2017-7814 – Mozilla: Blob and data URLs bypass phishing and malware protection warnings (MFSA 2017-22)
https://notcve.org/view.php?id=CVE-2017-7814
File downloads encoded with "blob:" and "data:" URL elements bypassed normal file download checks though the Phishing and Malware Protection feature and its block lists of suspicious sites and files. This would allow malicious sites to lure users into downloading executables that would otherwise be detected as suspicious. This vulnerability affects Firefox < 56, Firefox ESR < 52.4, and Thunderbird < 52.4. Las descargas de archivos codificados con elementos URL "blob:" y "data:" omitían las comprobaciones de descarga de archivos normales a pesar de la característica Phishing and Malware Protection y sus listas de bloqueo de páginas y archivos sospechosos. Esto permitiria a los sitios maliciosos engañar a los usuarios para que descarguen ejecutables que, de otra manera, se habrían detectado como sospechosos. • http://www.securityfocus.com/bid/101059 http://www.securitytracker.com/id/1039465 https://access.redhat.com/errata/RHSA-2017:2831 https://access.redhat.com/errata/RHSA-2017:2885 https://bugzilla.mozilla.org/show_bug.cgi?id=1376036 https://lists.debian.org/debian-lts-announce/2017/11/msg00000.html https://security.gentoo.org/glsa/201803-14 https://www.debian.org/security/2017/dsa-3987 https://www.debian.org/security/2017/dsa-4014 https://www.mozilla.org/security/advisor • CWE-20: Improper Input Validation CWE-494: Download of Code Without Integrity Check •
