CVE-2018-5740 – A flaw in the "deny-answer-aliases" feature can cause an assertion failure in named
https://notcve.org/view.php?id=CVE-2018-5740
"deny-answer-aliases" is a little-used feature intended to help recursive server operators protect end users against DNS rebinding attacks, a potential method of circumventing the security model used by client browsers. However, a defect in this feature makes it easy, when the feature is in use, to experience an assertion failure in name.c. Affects BIND 9.7.0->9.8.8, 9.9.0->9.9.13, 9.10.0->9.10.8, 9.11.0->9.11.4, 9.12.0->9.12.2, 9.13.0->9.13.2. "deny-answer-aliases" es una característica poco utilizada que pretende ayudar a los operadores recursivos del servidor a proteger a los usuarios finales contra ataques de reenlace DNS, un método para poder eludir el modelo de seguridad empleado por los navegadores del cliente. Sin embargo, un defecto en esta característica hace que sea sencillo experimentar un fallo de aserción en name.c. • http://lists.opensuse.org/opensuse-security-announce/2019-06/msg00026.html http://lists.opensuse.org/opensuse-security-announce/2019-06/msg00027.html http://www.securityfocus.com/bid/105055 http://www.securitytracker.com/id/1041436 https://access.redhat.com/errata/RHSA-2018:2570 https://access.redhat.com/errata/RHSA-2018:2571 https://kb.isc.org/docs/aa-01639 https://lists.debian.org/debian-lts-announce/2018/08/msg00033.html https://lists.debian.org/debian-lts-announce/2021/11 • CWE-617: Reachable Assertion •
CVE-2018-15473 – OpenSSH < 7.7 - User Enumeration
https://notcve.org/view.php?id=CVE-2018-15473
OpenSSH through 7.7 is prone to a user enumeration vulnerability due to not delaying bailout for an invalid authenticating user until after the packet containing the request has been fully parsed, related to auth2-gss.c, auth2-hostbased.c, and auth2-pubkey.c. OpenSSH hasta la versión 7.7 es propenso a una vulnerabilidad de enumeración de usuarios debido a que no retrasa el rescate de un usuario de autenticación no válido hasta que el paquete que contiene la petición haya sido analizado completamente. Esto está relacionado con auth2-gss.c, auth2-hostbased.c, y auth2-pubkey.c. A user enumeration vulnerability flaw was found in OpenSSH, though version 7.7. The vulnerability occurs by not delaying bailout for an invalid authenticated user until after the packet containing the request has been fully parsed. • https://www.exploit-db.com/exploits/45939 https://www.exploit-db.com/exploits/45233 https://www.exploit-db.com/exploits/45210 https://github.com/Rhynorater/CVE-2018-15473-Exploit https://github.com/r3dxpl0it/CVE-2018-15473 https://github.com/Sait-Nuri/CVE-2018-15473 https://github.com/LINYIKAI/CVE-2018-15473-exp https://github.com/MrDottt/CVE-2018-15473 https://github.com/yZ1337/CVE-2018-15473 https://github.com/1stPeak/CVE-2018-15473 https://github.com/0xrobiu • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •
CVE-2018-2952 – OpenJDK: insufficient index validation in PatternSyntaxException getMessage() (Concurrency, 8199547)
https://notcve.org/view.php?id=CVE-2018-2952
Vulnerability in the Java SE, Java SE Embedded, JRockit component of Oracle Java SE (subcomponent: Concurrency). Supported versions that are affected are Java SE: 6u191, 7u181, 8u172 and 10.0.1; Java SE Embedded: 8u171; JRockit: R28.3.18. Difficult to exploit vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Java SE, Java SE Embedded, JRockit. Successful attacks of this vulnerability can result in unauthorized ability to cause a partial denial of service (partial DOS) of Java SE, Java SE Embedded, JRockit.

CVE-2018-12015 – perl: Directory traversal in Archive::Tar
https://notcve.org/view.php?id=CVE-2018-12015
In Perl through 5.26.2, the Archive::Tar module allows remote attackers to bypass a directory-traversal protection mechanism, and overwrite arbitrary files, via an archive file containing a symlink and a regular file with the same name. En Perl hasta la versión 5.26.2, el módulo Archive::Tar permite que atacantes remotos omitan un mecanismo de protección de salto de directorio y sobrescriban archivos arbitrarios mediante un archivo comprimido que contiene un symlink y un archivo normal con el mismo nombre. It was found that the Archive::Tar module did not properly sanitize symbolic links when extracting tar archives. An attacker, able to provide a specially crafted archive for processing, could use this flaw to write or overwrite arbitrary files in the context of the Perl interpreter. • http://seclists.org/fulldisclosure/2019/Mar/49 http://www.securityfocus.com/bid/104423 http://www.securitytracker.com/id/1041048 https://access.redhat.com/errata/RHSA-2019:2097 https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=900834 https://seclists.org/bugtraq/2019/Mar/42 https://security.netapp.com/advisory/ntap-20180927-0001 https://support.apple.com/kb/HT209600 https://usn.ubuntu.com/3684-1 https://usn.ubuntu.com/3684-2 https://www.debian.org/security/2018& • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') CWE-59: Improper Link Resolution Before File Access ('Link Following') •
