CVSS: 8.1EPSS: 97%CPEs: 68EXPL: 10CVE-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 •

ssl/s2_srvr.c in OpenSSL 1.0.1 before 1.0.1r and 1.0.2 before 1.0.2f does not prevent use of disabled ciphers, which makes it easier for man-in-the-middle attackers to defeat cryptographic protection mechanisms by performing computations on SSLv2 traffic, related to the get_client_master_key and get_client_hello functions. ssl/s2_srvr.c en OpenSSL 1.0.1 en versiones anteriores a 1.0.1r y 1.0.2 en versiones anteriores a 1.0.2f no impide el uso de cifrados deshabilitados, lo que hace que sea más fácil para atacantes man-in-the-middle vencer los mecanismos de protección criptográfica llevando a cabo cálculos sobre tráfico SSLv2, relacionado con las funciones get_client_master_key y get_client_hello. A flaw was found in the way malicious SSLv2 clients could negotiate SSLv2 ciphers that were disabled on the server. This could result in weak SSLv2 ciphers being used for SSLv2 connections, making them vulnerable to man-in-the-middle attacks. • http://kb.juniper.net/InfoCenter/index?page=content&id=JSA10759 http://lists.fedoraproject.org/pipermail/package-announce/2016-January/176373.html http://lists.opensuse.org/opensuse-security-announce/2016-03/msg00001.html http://lists.opensuse.org/opensuse-security-announce/2016-03/msg00002.html http://lists.opensuse.org/opensuse-security-announce/2016-03/msg00003.html http://lists.opensuse.org/opensuse-security-announce/2016-03/msg00004.html http://lists.opensuse.org/opensuse-security-announce/2016-03/msg00 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-310: Cryptographic Issues •

Heap-based buffer overflow in the __nss_hostname_digits_dots function in glibc 2.2, and other 2.x versions before 2.18, allows context-dependent attackers to execute arbitrary code via vectors related to the (1) gethostbyname or (2) gethostbyname2 function, aka "GHOST." Desbordamiento de buffer basado en memoria dinámica en la función __nss_hostname_digits_dots en glibc 2.2, y otras versiones 2.x anteriores a 2.18, permite a atacantes dependientes de contexto ejecutar código arbitrario a través de vectores relacionados con la funciín (1) gethostbyname o (2) gethostbyname2, también conocido como 'GHOST.' A heap-based buffer overflow was found in glibc's __nss_hostname_digits_dots() function, which is used by the gethostbyname() and gethostbyname2() glibc function calls. A remote attacker able to make an application call either of these functions could use this flaw to execute arbitrary code with the permissions of the user running the application. The industrial managed switch series 852 from WAGO is affected by multiple vulnerabilities such as old software components embedded in the firmware. • https://www.exploit-db.com/exploits/35951 https://www.exploit-db.com/exploits/36421 https://github.com/aaronfay/CVE-2015-0235-test https://github.com/makelinux/CVE-2015-0235-workaround https://github.com/sUbc0ol/CVE-2015-0235 https://github.com/mikesplain/CVE-2015-0235-cookbook https://github.com/tobyzxj/CVE-2015-0235 https://github.com/adherzog/ansible-CVE-2015-0235-GHOST http://blogs.sophos.com/2015/01/29/sophos-products-and-the-ghost-vulnerability-affecting-linux http:/ • CWE-122: Heap-based Buffer Overflow CWE-787: Out-of-bounds Write •
