CVSS: 5.9EPSS: 0%CPEs: 1EXPL: 0CVE-2017-12132 – glibc: Fragmentation attacks possible when EDNS0 is enabled
https://notcve.org/view.php?id=CVE-2017-12132
The DNS stub resolver in the GNU C Library (aka glibc or libc6) before version 2.26, when EDNS support is enabled, will solicit large UDP responses from name servers, potentially simplifying off-path DNS spoofing attacks due to IP fragmentation. La herramienta de resolución de zonas stub de DNS en la librería GNU C, también conocida como glibc o libc6, en sus versiones anteriores a la 2.26 cuando el soporte EDNS está activado, solicitará respuestas UDP de gran tamaño de servidores de nombres, pudiendo simplificar los ataques de suplantación de DNS debido a una fragmentación de IP. • http://www.securityfocus.com/bid/100598 https://access.redhat.com/errata/RHSA-2018:0805 https://arxiv.org/pdf/1205.4011.pdf https://sourceware.org/bugzilla/show_bug.cgi?id=21361 https://access.redhat.com/security/cve/CVE-2017-12132 https://bugzilla.redhat.com/show_bug.cgi?id=1477529 • CWE-770: Allocation of Resources Without Limits or Throttling •

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 •

An integer overflow in the implementation of the posix_memalign in memalign functions in the GNU C Library (aka glibc or libc6) 2.26 and earlier could cause these functions to return a pointer to a heap area that is too small, potentially leading to heap corruption. Un desbordamiento de enteros en la implementación de posix_memalign en las funciones memalign en GNU C Library (también conocido como glibc o libc6) en versiones 2.26 y anteriores podría provocar que estas funciones devuelvan un puntero a un área de la memoria dinámica (heap) demasiado pequeña, pudiendo corromper el heap. • http://bugs.debian.org/878159 http://www.securityfocus.com/bid/102912 https://access.redhat.com/errata/RHBA-2019:0327 https://access.redhat.com/errata/RHSA-2018:3092 https://security.netapp.com/advisory/ntap-20190404-0003 https://sourceware.org/bugzilla/show_bug.cgi?id=22343 https://usn.ubuntu.com/4218-1 https://usn.ubuntu.com/4416-1 https://www.oracle.com/technetwork/security-advisory/cpuapr2019-5072813.html https://access.redhat.com/security/cve/CVE-2018-6485 https:/ • CWE-190: Integer Overflow or Wraparound CWE-787: Out-of-bounds Write •
