https://notcve.org/view.php?id=CVE-2016-3706
Stack-based buffer overflow in the getaddrinfo function in sysdeps/posix/getaddrinfo.c in the GNU C Library (aka glibc or libc6) allows remote attackers to cause a denial of service (crash) via vectors involving hostent conversion. NOTE: this vulnerability exists because of an incomplete fix for CVE-2013-4458. Desbordamiento del buffer basado en pila en la función getaddrinfo en sysdeps/posix/getaddrinfo.c en GNU C Library (también conocida como glibc o libc6) permite a atacantes remotos provocar una denegación de servicio (caída) a través de vectores relacionados con la conversión hostent.

CVE-2016-1234 – Moxa Command Injection / Cross Site Scripting / Vulnerable Software
https://notcve.org/view.php?id=CVE-2016-1234
Stack-based buffer overflow in the glob implementation in GNU C Library (aka glibc) before 2.24, when GLOB_ALTDIRFUNC is used, allows context-dependent attackers to cause a denial of service (crash) via a long name. Desbordamiento de buffer basado en pila en la implementación glob en GNU C Library (también conocido como glibc) en versiones anteriores a 2.24, cuando es usado GLOB_ALTDIRFUNC, permite a atacantes dependientes de contexto provocar una denegación de servicio (caída) a través de un nombre largo.

CVE-2016-2856 – Ubuntu < 15.10 - PT Chown Arbitrary PTs Access Via User Namespace Privilege Escalation
https://notcve.org/view.php?id=CVE-2016-2856
pt_chown in the glibc package before 2.19-18+deb8u4 on Debian jessie; the elibc package before 2.15-0ubuntu10.14 on Ubuntu 12.04 LTS and before 2.19-0ubuntu6.8 on Ubuntu 14.04 LTS; and the glibc package before 2.21-0ubuntu4.2 on Ubuntu 15.10 and before 2.23-0ubuntu1 on Ubuntu 16.04 LTS and 16.10 lacks a namespace check associated with file-descriptor passing, which allows local users to capture keystrokes and spoof data, and possibly gain privileges, via pts read and write operations, related to debian/sysdeps/linux.mk. NOTE: this is not considered a vulnerability in the upstream GNU C Library because the upstream documentation has a clear security recommendation against the --enable-pt_chown option. pt_chown en el paquete glibc en versiones anteriores a 2.19-18+deb8u4 en Debian jessie; el paquete elibc en versiones anteriores a 2.15-0ubuntu10.14 en Ubuntu 12.04 LTS y en versiones anteriores a 2.19-0ubuntu6.8 en Ubuntu 14.04 LTS; y el paquete glibc en versiones anteriores a 2.21-0ubuntu4.2 en Ubuntu 15.10 y en versiones anteriores a 2.23-0ubuntu1 en Ubuntu 16.04 LTS y 16.10 carece de verificación de paso de espacio de nombres asociado a la ejecución del descriptor de archivo, lo que permite a usuarios locales capturar pulsaciones del teclado y suplantar datos, y posiblemente obtener privilegios, a través de operaciones pts de lectura y escritura, relacionado con debian/sysdeps/linux.mk. NOTA: no está considerada una vulnerabilidad inicial en la GNU C Library porque la documentación de distribución tiene una clara recomendación de seguridad frente a la opción --enable-pt_chown. Ubuntu versions prior to 15.10 suffer from a PT chown arbitrary PTs access via user namespace privilege escalation vulnerability. • https://www.exploit-db.com/exploits/41760 http://anonscm.debian.org/cgit/pkg-glibc/glibc.git/commit/?h=jessie&id=09f7764882a81e13e7b5d87d715412283a6ce403 http://anonscm.debian.org/cgit/pkg-glibc/glibc.git/commit/?h=jessie&id=11475c083282c1582c4dd72eecfcb2b7d308c958 http://people.canonical.com/~ubuntu-security/cve/2016/CVE-2016-2856.html http://www.halfdog.net/Security/2015/PtChownArbitraryPtsAccessViaUserNamespace http://www.openwall.com/lists/oss-security/2016/02/23/3 http://www.openwall.com/lists/oss • CWE-264: Permissions, Privileges, and Access Controls •
CVE-2015-5277 – glibc: data corruption while reading the NSS files database
https://notcve.org/view.php?id=CVE-2015-5277
The get_contents function in nss_files/files-XXX.c in the Name Service Switch (NSS) in GNU C Library (aka glibc or libc6) before 2.20 might allow local users to cause a denial of service (heap corruption) or gain privileges via a long line in the NSS files database. La función get_contents en nss_files/files-XXX.c en el Name Service Switch (NSS) en GNU C Library (también conocida como glibc o libc6) en versiones anteriores a 2.20 puede permitir a usuarios locales causar una denegación de servicio (corrupción de pila) o ganar privilegios a través de una larga fila en la base de datos de archivos NSS. It was discovered that the nss_files backend for the Name Service Switch in glibc would return incorrect data to applications or corrupt the heap (depending on adjacent heap contents). A local attacker could potentially use this flaw to execute arbitrary code on the system. Many Cisco devices such as Cisco RV340, Cisco RV340W, Cisco RV345, Cisco RV345P, Cisco RV260, Cisco RV260P, Cisco RV260W, Cisco 160, and Cisco 160W suffer from having hard-coded credentials, known GNU glibc, known BusyBox, and IoT Inspector identified vulnerabilities. • http://packetstormsecurity.com/files/154361/Cisco-Device-Hardcoded-Credentials-GNU-glibc-BusyBox.html http://rhn.redhat.com/errata/RHSA-2015-2172.html http://seclists.org/fulldisclosure/2019/Sep/7 http://www.oracle.com/technetwork/topics/security/linuxbulletinoct2015-2719645.html http://www.securityfocus.com/bid/78092 http://www.securitytracker.com/id/1034196 http://www.ubuntu.com/usn/USN-2985-1 http://www.ubuntu.com/usn/USN-2985-2 https://bugzilla.redhat.com/show_bug.cgi?id=1262914& • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
