Artifex Ghostscript allows attackers to bypass a sandbox protection mechanism by leveraging exposure of system operators in the saved execution stack in an error object. Artifex Ghostscript permite que los atacantes omitan un mecanismo de protección de sandbox aprovechando la exposición de los operadores del sistema en la pila de ejecución guardada en un objeto error. • http://git.ghostscript.com/?p=ghostpdl.git%3Ba=commit%3Bh=34cc326eb2c5695833361887fe0b32e8d987741c http://packetstormsecurity.com/files/149758/Ghostscript-Exposed-System-Operators.html http://www.openwall.com/lists/oss-security/2018/10/10/12 https://access.redhat.com/errata/RHSA-2018:3834 https://bugs.chromium.org/p/project-zero/issues/detail?id=1690 https://bugs.ghostscript.com/show_bug.cgi?id=699927 https://lists.debian.org/debian-lts-announce/2018/10/msg00013.html https://usn.ubuntu.com/ • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-460: Improper Cleanup on Thrown Exception •
CVSS: 7.5EPSS: 0%CPEs: 9EXPL: 2CVE-2018-18074 – python-requests: Redirect from HTTPS to HTTP does not remove Authorization header
https://notcve.org/view.php?id=CVE-2018-18074
The Requests package before 2.20.0 for Python sends an HTTP Authorization header to an http URI upon receiving a same-hostname https-to-http redirect, which makes it easier for remote attackers to discover credentials by sniffing the network. El paquete Requests antes de la versión 2.20.0 para Python envía una cabecera de autorización HTTP a un URI http al recibir una redirección same-hostname https-to-http, lo que facilita que los atacantes remotos descibran las credenciales esnifando la red. A credentials-exposure flaw was found in python-requests, where if a request with authentication is redirected (302) from an HTTPS endpoint to an HTTP endpoint on the same host, the Authorization header is not stripped and the credentials can be read in plain text. A man-in-the-middle attacker could exploit this flaw to obtain a user's valid credentials. • http://docs.python-requests.org/en/master/community/updates/#release-and-version-history http://lists.opensuse.org/opensuse-security-announce/2019-07/msg00024.html https://access.redhat.com/errata/RHSA-2019:2035 https://bugs.debian.org/910766 https://github.com/requests/requests/commit/c45d7c49ea75133e52ab22a8e9e13173938e36ff https://github.com/requests/requests/issues/4716 https://github.com/requests/requests/pull/4718 https://usn.ubuntu.com/3790-1 https://usn.ubuntu.com/3790-2 https:/& • CWE-522: Insufficiently Protected Credentials •
