CVSS: 7.5EPSS: 1%CPEs: 9EXPL: 0CVE-2015-5229 – glibc: calloc may return non-zero memory
https://notcve.org/view.php?id=CVE-2015-5229
The calloc function in the glibc package in Red Hat Enterprise Linux (RHEL) 6.7 and 7.2 does not properly initialize memory areas, which might allow context-dependent attackers to cause a denial of service (hang or crash) via unspecified vectors. La función calloc en el paquete glibc en Red Hat Enterprise Linux (RHEL) 6.7 y 7.2 no inicializa adecuadamente áreas de memoria, lo que podría permitir a atacantes dependientes de contexto provocar una denegación de servicio (colgado o caída) a través de vectores no especificados. It was discovered that the calloc implementation in glibc could return memory areas which contain non-zero bytes. This could result in unexpected application behavior such as hangs or crashes. • http://rhn.redhat.com/errata/RHSA-2016-0176.html http://www.oracle.com/technetwork/topics/security/linuxbulletinjan2016-2867209.html http://www.securityfocus.com/bid/84172 https://bugzilla.redhat.com/show_bug.cgi?id=1246713 https://bugzilla.redhat.com/show_bug.cgi?id=1256285 https://bugzilla.redhat.com/show_bug.cgi?id=1293976 https://kc.mcafee.com/corporate/index?page=content&id=SB10150 https://access.redhat.com/security/cve/CVE-2015-5229 • CWE-17: DEPRECATED: Code •
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 •

https://notcve.org/view.php?id=CVE-2016-0741
slapd/connection.c in 389 Directory Server (formerly Fedora Directory Server) 1.3.4.x before 1.3.4.7 allows remote attackers to cause a denial of service (infinite loop and connection blocking) by leveraging an abnormally closed connection. slapd/connection.c en 389 Directory Server (anteriormente Fedora Directory Server) 1.3.4.x en versiones anteriores a 1.3.4.7 permite a atacantes remotos causar una denegación de servicio (bucle infinito y bloqueo de conexion) aprovechándose de una conexión cerrada de manera anómala. An infinite-loop vulnerability was discovered in the 389 directory server, where the server failed to correctly handle unexpectedly closed client connections. A remote attacker able to connect to the server could use this flaw to make the directory server consume an excessive amount of CPU and stop accepting connections (denial of service). • http://directory.fedoraproject.org/docs/389ds/releases/release-1-3-4-7.html http://rhn.redhat.com/errata/RHSA-2016-0204.html http://www.oracle.com/technetwork/topics/security/linuxbulletinjan2016-2867209.html http://www.securityfocus.com/bid/82343 https://fedorahosted.org/389/changeset/cd45d032421b0ecf76d8cbb9b1c3aeef7680d9a2 https://fedorahosted.org/389/ticket/48412 https://access.redhat.com/security/cve/CVE-2016-0741 https://bugzilla.redhat.com/show_bug.cgi?id=1299416 • CWE-399: Resource Management Errors CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop') •
