https://notcve.org/view.php?id=CVE-2018-17958
Qemu has a Buffer Overflow in rtl8139_do_receive in hw/net/rtl8139.c because an incorrect integer data type is used. Qemu tiene un desbordamiento de búfer en rtl8139_do_receive en hw/net/rtl8139.c debido a que se emplea un tipo de datos de enteros incorrecto. An integer overflow issue was found in the RTL8139 NIC emulation in QEMU. It could occur while receiving packets over the network if the size value is greater than INT_MAX. Such overflow would lead to stack buffer overflow issue. • http://www.openwall.com/lists/oss-security/2018/10/08/1 http://www.securityfocus.com/bid/105556 https://access.redhat.com/errata/RHSA-2019:2425 https://access.redhat.com/errata/RHSA-2019:2553 https://lists.debian.org/debian-lts-announce/2019/01/msg00023.html https://lists.gnu.org/archive/html/qemu-devel/2018-09/msg03269.html https://seclists.org/bugtraq/2019/May/76 https://usn.ubuntu.com/3826-1 https://www.debian.org/security/2019/dsa-4454 https://access& • CWE-121: Stack-based Buffer Overflow CWE-190: Integer Overflow or Wraparound •
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 •
