CVE-2017-7668 – httpd: ap_find_token() buffer overread
https://notcve.org/view.php?id=CVE-2017-7668
The HTTP strict parsing changes added in Apache httpd 2.2.32 and 2.4.24 introduced a bug in token list parsing, which allows ap_find_token() to search past the end of its input string. By maliciously crafting a sequence of request headers, an attacker may be able to cause a segmentation fault, or to force ap_find_token() to return an incorrect value. Los cambios en el análisis sintáctico estricto de HTTP añadidos en las versiones 2.2.32 y 2.4.24 de Apache httpd introdujeron un error en el análisis de listas de tokens. Esto permite que ap_find_token() busque más allá del final de la cadena de entrada. Un atacante puede conseguir causar un fallo de segmentación o forzar a que ap_find_token() devuelva un valor incorrecto mediante la manipulación de una secuencia de cabeceras de peticiones con fines maliciosos. • http://www.debian.org/security/2017/dsa-3896 http://www.oracle.com/technetwork/security-advisory/cpuoct2017-3236626.html http://www.securityfocus.com/bid/99137 http://www.securitytracker.com/id/1038711 https://access.redhat.com/errata/RHSA-2017:2479 https://access.redhat.com/errata/RHSA-2017:2483 https://access.redhat.com/errata/RHSA-2017:3193 https://access.redhat.com/errata/RHSA-2017:3194 https://lists.apache.org/thread.html/55a068b6a5eec0b3198ae7d96a7cb412352d0ffa7716612c5af3745b%40%3Cdev.httpd. • CWE-122: Heap-based Buffer Overflow CWE-125: Out-of-bounds Read CWE-126: Buffer Over-read •
CVE-2017-3167 – httpd: ap_get_basic_auth_pw() authentication bypass
https://notcve.org/view.php?id=CVE-2017-3167
In Apache httpd 2.2.x before 2.2.33 and 2.4.x before 2.4.26, use of the ap_get_basic_auth_pw() by third-party modules outside of the authentication phase may lead to authentication requirements being bypassed. En Apache httpd, en versiones 2.2.x anteriores a la 2.2.33 y versiones 2.4.x anteriores a la 2.4.26, el uso de ap_get_basic_auth_pw() por parte de módulos de terceros fuera de la fase de autenticación puede dar lugar a que se omitan requisitos de autenticación.. It was discovered that the use of httpd's ap_get_basic_auth_pw() API function outside of the authentication phase could lead to authentication bypass. A remote attacker could possibly use this flaw to bypass required authentication if the API was used incorrectly by one of the modules used by httpd. • http://www.debian.org/security/2017/dsa-3896 http://www.oracle.com/technetwork/security-advisory/cpuoct2017-3236626.html http://www.securityfocus.com/bid/99135 http://www.securitytracker.com/id/1038711 https://access.redhat.com/errata/RHSA-2017:2478 https://access.redhat.com/errata/RHSA-2017:2479 https://access.redhat.com/errata/RHSA-2017:2483 https://access.redhat.com/errata/RHSA-2017:3193 https://access.redhat.com/errata/RHSA-2017:3194 https://access.redhat.com/errata/RHS • CWE-287: Improper Authentication •
CVE-2017-1000366 – Linux Kernel (Debian 9/10 / Ubuntu 14.04.5/16.04.2/17.04 / Fedora 23/24/25) - 'ldso_dynamic Stack Clash' Local Privilege Escalation
https://notcve.org/view.php?id=CVE-2017-1000366
glibc contains a vulnerability that allows specially crafted LD_LIBRARY_PATH values to manipulate the heap/stack, causing them to alias, potentially resulting in arbitrary code execution. Please note that additional hardening changes have been made to glibc to prevent manipulation of stack and heap memory but these issues are not directly exploitable, as such they have not been given a CVE. This affects glibc 2.25 and earlier. Glibc contiene una vulnerabilidad que permite que los valores LD_LIBRARY_PATH especialmente creados para manipular la región heap/stack de la memoria, generando entonces un alias, lo que podría conllevar a la ejecución del código arbitrario. Tenga en cuenta que se han realizado cambios de refuerzo adicionales en glibc para evitar la manipulación del stack y heap de la memoria de almacenamiento dinámico, pero estos problemas no se pueden explotar directamente, por lo que no se les ha otorgado un CVE. • https://www.exploit-db.com/exploits/42276 https://www.exploit-db.com/exploits/42274 https://www.exploit-db.com/exploits/42275 http://packetstormsecurity.com/files/154361/Cisco-Device-Hardcoded-Credentials-GNU-glibc-BusyBox.html http://seclists.org/fulldisclosure/2019/Sep/7 http://www.debian.org/security/2017/dsa-3887 http://www.securityfocus.com/bid/99127 http://www.securitytracker.com/id/1038712 https://access.redhat.com/errata/RHSA-2017:1479 https://access.redhat.com/errata/ • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
CVE-2017-9462 – mercurial: Python debugger accessible to authorized users
https://notcve.org/view.php?id=CVE-2017-9462
In Mercurial before 4.1.3, "hg serve --stdio" allows remote authenticated users to launch the Python debugger, and consequently execute arbitrary code, by using --debugger as a repository name. En Mercurial, en versiones anteriores a la 4.1.3, \"hg serve --stdio\" permite que usuarios autenticados remotos inicien el depurador de Python y, como consecuencia, ejecuten código arbitrario utilizando --debugger como nombre del repositorio. A flaw was found in the way "hg serve --stdio" command in Mercurial handled command-line options. A remote, authenticated attacker could use this flaw to execute arbitrary code on the Mercurial server by using specially crafted command-line options. • http://www.debian.org/security/2017/dsa-3963 http://www.securityfocus.com/bid/99123 https://access.redhat.com/errata/RHSA-2017:1576 https://bugs.debian.org/861243 https://lists.debian.org/debian-lts-announce/2018/07/msg00005.html https://security.gentoo.org/glsa/201709-18 https://www.mercurial-scm.org/repo/hg/rev/77eaf9539499 https://www.mercurial-scm.org/wiki/WhatsNew#Mercurial_4.1.3_.282017-4-18.29 https://access.redhat.com/security/cve/CVE-2017-9462 https: • CWE-284: Improper Access Control CWE-732: Incorrect Permission Assignment for Critical Resource •
