The xdr_bytes and xdr_string functions in the GNU C Library (aka glibc or libc6) 2.25 mishandle failures of buffer deserialization, which allows remote attackers to cause a denial of service (virtual memory allocation, or memory consumption if an overcommit setting is not used) via a crafted UDP packet to port 111, a related issue to CVE-2017-8779. NOTE: [Information provided from upstream and references **EN DISPUTA** Las funciones xdr_bytes y xdr_string en la librería GNU C (conocida como glibc o libc6) 2.25 no maneja adecuadamente los fallos de deserialización de buffer, lo que permite a atacantes remotos causar una denegación de servicio a través de paquetes UDP manipulados en el puerto 111, un problema relacionado con CVE-2017-8779.

CVSS: 9.3EPSS: 0%CPEs: 10EXPL: 1CVE-2017-16997 – glibc: Incorrect handling of RPATH in elf/dl-load.c can be used to execute code loaded from arbitrary libraries
https://notcve.org/view.php?id=CVE-2017-16997
elf/dl-load.c in the GNU C Library (aka glibc or libc6) 2.19 through 2.26 mishandles RPATH and RUNPATH containing $ORIGIN for a privileged (setuid or AT_SECURE) program, which allows local users to gain privileges via a Trojan horse library in the current working directory, related to the fillin_rpath and decompose_rpath functions. This is associated with misinterpretion of an empty RPATH/RUNPATH token as the "./" directory. NOTE: this configuration of RPATH/RUNPATH for a privileged program is apparently very uncommon; most likely, no such program is shipped with any common Linux distribution. elf/dl-load.c en la biblioteca GNU C (también llamada glibc o libc6) desde la versión 2.19 hasta la 2.26 manipula incorrectamente RPATH y RUNPATH que contienen $ORIGIN para un programa privilegiado (setuid o AT_SECURE), lo que permite que los usuarios locales obtengan privilegios mediante una librería con malware troyano en el directorio actual. Esto está relacionado con las funciones fillin_rpath y decompose_rpath. Esto se asocia con la interpretación incorrecta de un token RPATH/RUNPATH vacío como el directorio "./". • https://github.com/Xiami2012/CVE-2017-16997-poc http://www.securityfocus.com/bid/102228 https://access.redhat.com/errata/RHBA-2019:0327 https://access.redhat.com/errata/RHSA-2018:3092 https://bugs.debian.org/884615 https://sourceware.org/bugzilla/show_bug.cgi?id=22625 https://sourceware.org/ml/libc-alpha/2017-12/msg00528.html https://access.redhat.com/security/cve/CVE-2017-16997 https://bugzilla.redhat.com/show_bug.cgi?id=1526865 • CWE-426: Untrusted Search Path CWE-470: Use of Externally-Controlled Input to Select Classes or Code ('Unsafe Reflection') •

https://notcve.org/view.php?id=CVE-2018-6485
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 •
