CVE-2015-7547 – glibc - 'getaddrinfo' Stack Buffer Overflow (PoC)
https://notcve.org/view.php?id=CVE-2015-7547
Multiple stack-based buffer overflows in the (1) send_dg and (2) send_vc functions in the libresolv library in the GNU C Library (aka glibc or libc6) before 2.23 allow remote attackers to cause a denial of service (crash) or possibly execute arbitrary code via a crafted DNS response that triggers a call to the getaddrinfo function with the AF_UNSPEC or AF_INET6 address family, related to performing "dual A/AAAA DNS queries" and the libnss_dns.so.2 NSS module. Múltiples desbordamientos de buffer basado en pila en las funciones (1) send_dg y (2) send_vc en la librería libresolv en la librería GNU C (también conocida como glibc o libc6) en versiones anteriores a 2.23 permiten a atacantes remotos causar una denegación de servicio (caída) o posiblemente ejecutar código arbitrario a través de una respuesta DNS manipulada que desencadenan una llamada a la función getaddrinfo con la familia de direcciones AF_UNSPEC o AF_INET6, en relación con la ejecución de "consultas duales A/AAAA DNS" y el módulo libnss_dns.so.2 NSS. A stack-based buffer overflow was found in the way the libresolv library performed dual A/AAAA DNS queries. A remote attacker could create a specially crafted DNS response which could cause libresolv to crash or, potentially, execute code with the permissions of the user running the library. Note: this issue is only exposed when libresolv is called from the nss_dns NSS service module. • https://www.exploit-db.com/exploits/39454 https://www.exploit-db.com/exploits/40339 https://github.com/fjserna/CVE-2015-7547 https://github.com/cakuzo/CVE-2015-7547 https://github.com/Stick-U235/CVE-2015-7547-Research https://github.com/t0r0t0r0/CVE-2015-7547 https://github.com/babykillerblack/CVE-2015-7547 https://github.com/Amilaperera12/Glibc-Vulnerability-Exploit-CVE-2015-7547 https://github.com/miracle03/CVE-2015-7547-master https://github.com/bluebluelan/CVE-2015-7547 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-121: Stack-based Buffer Overflow •
CVE-2015-8779 – glibc: Unbounded stack allocation in catopen function
https://notcve.org/view.php?id=CVE-2015-8779
Stack-based buffer overflow in the catopen function in the GNU C Library (aka glibc or libc6) before 2.23 allows context-dependent attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a long catalog name. Desbordamiento de buffer basado en pila en la función catopen en la GNU C Library (también conocida como glibc o libc6) en versiones anteriores a 2.23 permite a atacantes dependientes de contexto causar una denegación de servicio (caída de aplicación) o posiblemente ejecutar código arbitrario a través de un nombre de catálogo largo. A stack based buffer overflow vulnerability was found in the catopen() function. An excessively long string passed to the function could cause it to crash or, potentially, execute arbitrary code.

CVE-2016-3075 – glibc: Stack overflow in nss_dns_getnetbyname_r
https://notcve.org/view.php?id=CVE-2016-3075
Stack-based buffer overflow in the nss_dns implementation of the getnetbyname function in GNU C Library (aka glibc) before 2.24 allows context-dependent attackers to cause a denial of service (stack consumption and application crash) via a long name. Desbordamiento de buffer basado en pila en la implementación nss_dns de la función getnetbyname en GNU C Library (también conocido como glibc) en versiones anteriores a 2.24 permite a atacantes dependientes del contexto provocar una denegación de servicio (consumo de pila y caída de aplicación) a través de un nombre largo. A stack overflow vulnerability was found in _nss_dns_getnetbyname_r. On systems with nsswitch configured to include "networks: dns" with a privileged or network-facing service that would attempt to resolve user-provided network names, an attacker could provide an excessively long network name, resulting in stack corruption and code execution. • http://lists.fedoraproject.org/pipermail/package-announce/2016-May/184626.html http://lists.opensuse.org/opensuse-updates/2016-06/msg00030.html http://lists.opensuse.org/opensuse-updates/2016-07/msg00039.html http://rhn.redhat.com/errata/RHSA-2016-2573.html http://www.securityfocus.com/bid/85732 http://www.ubuntu.com/usn/USN-2985-1 https://security.gentoo.org/glsa/201702-11 https://sourceware.org/bugzilla/show_bug.cgi?id=19879 https://sourceware.org/git/gitweb.cgi?p=glibc. • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-121: Stack-based Buffer Overflow •
CVE-2014-9761 – glibc: Unbounded stack allocation in nan* functions
https://notcve.org/view.php?id=CVE-2014-9761
Multiple stack-based buffer overflows in the GNU C Library (aka glibc or libc6) before 2.23 allow context-dependent attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a long argument to the (1) nan, (2) nanf, or (3) nanl function. Múltiples desbordamientos de buffer basado en pila en la GNU C Library (también conocida como glibc o libc6) en versiones anteriores a 2.23 permiten a atacantes dependientes del contexto causar una denegación de servicio (caída de aplicación) o posiblemente ejecutar código arbirario a través de un argumento largo en la función (1) nan, (2) nanf o (3) nanl.

CVE-2015-8778 – glibc: Integer overflow in hcreate and hcreate_r
https://notcve.org/view.php?id=CVE-2015-8778
Integer overflow in the GNU C Library (aka glibc or libc6) before 2.23 allows context-dependent attackers to cause a denial of service (application crash) or possibly execute arbitrary code via the size argument to the __hcreate_r function, which triggers out-of-bounds heap-memory access. Desbordamiento de entero en la GNU C Library (también conocida como glibc o libc6) en versiones anteriores a 2.23 permite a atacantes dependientes del contexto causar una denegación de servicio (caída de aplicación) o posiblemente ejecutar código arbitrario a través del argumento size a la función the __hcreate_r, lo que desencandena el acceso fuera de rango a memoria dinámica. An integer overflow vulnerability was found in hcreate() and hcreate_r() functions which could result in an out-of-bounds memory access.
