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 •
CVSS: 7.8EPSS: 0%CPEs: 38EXPL: 5CVE-2016-0728 – Linux Kernel 4.4.1 - REFCOUNT Overflow Use-After-Free in Keyrings Local Privilege Escalation
https://notcve.org/view.php?id=CVE-2016-0728
The join_session_keyring function in security/keys/process_keys.c in the Linux kernel before 4.4.1 mishandles object references in a certain error case, which allows local users to gain privileges or cause a denial of service (integer overflow and use-after-free) via crafted keyctl commands. La función join_session_keyring en security/keys/process_keys.c en el kernel de Linux en versiones anteriores a 4.4.1 no maneja correctamente referencias a objetos en un cierto caso de error, lo que permite a usuarios locales obtener privilegios o provocar una denegación de servicio (desbordamiento de entero y uso después de liberación) a través de comandos keyctl manipulados. A use-after-free flaw was found in the way the Linux kernel's key management subsystem handled keyring object reference counting in certain error path of the join_session_keyring() function. A local, unprivileged user could use this flaw to escalate their privileges on the system. • https://www.exploit-db.com/exploits/40003 https://www.exploit-db.com/exploits/39277 https://github.com/hal0taso/CVE-2016-0728 https://github.com/googleweb/CVE-2016-0728 https://github.com/th30d00r/Linux-Vulnerability-CVE-2016-0728-and-Exploit http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=23567fd052a9abb6d67fe8e7a9ccdd9800a540f2 http://lists.fedoraproject.org/pipermail/package-announce/2016-February/176484.html http://lists.fedoraproject.org/pipermail/package-announce/2016 • CWE-416: Use After Free •
