CVSS: 5.9EPSS: 1%CPEs: 180EXPL: 0CVE-2019-1559 – 0-byte record padding oracle
https://notcve.org/view.php?id=CVE-2019-1559
If an application encounters a fatal protocol error and then calls SSL_shutdown() twice (once to send a close_notify, and once to receive one) then OpenSSL can respond differently to the calling application if a 0 byte record is received with invalid padding compared to if a 0 byte record is received with an invalid MAC. If the application then behaves differently based on that in a way that is detectable to the remote peer, then this amounts to a padding oracle that could be used to decrypt data. In order for this to be exploitable "non-stitched" ciphersuites must be in use. Stitched ciphersuites are optimised implementations of certain commonly used ciphersuites. Also the application must call SSL_shutdown() twice even if a protocol error has occurred (applications should not do this but some do anyway). • http://lists.opensuse.org/opensuse-security-announce/2019-03/msg00041.html http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00019.html http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00046.html http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00047.html http://lists.opensuse.org/opensuse-security-announce/2019-05/msg00049.html http://lists.opensuse.org/opensuse-security-announce/2019-06/msg00080.html http://www.securityfocus.com/bid/107174 https://access. • CWE-203: Observable Discrepancy CWE-325: Missing Cryptographic Step •
CVSS: 7.5EPSS: 0%CPEs: 3EXPL: 1CVE-2018-20657 – libiberty: Memory leak in demangle_template function resulting in a denial of service
https://notcve.org/view.php?id=CVE-2018-20657
The demangle_template function in cplus-dem.c in GNU libiberty, as distributed in GNU Binutils 2.31.1, has a memory leak via a crafted string, leading to a denial of service (memory consumption), as demonstrated by cxxfilt, a related issue to CVE-2018-12698. La función demangle_template en cplus-dem.c en GNU libiberty, como se distribuyó en la versión 2.31.1, tiene una fuga de memoria mediante una cadena manipulada, provocando una denegación de servicio (consumo de memoria), tal y como queda demostrado con cxxfilt.

CVSS: 10.0EPSS: 89%CPEs: 345EXPL: 17CVE-2014-7169 – GNU Bourne-Again Shell (Bash) Arbitrary Code Execution Vulnerability
https://notcve.org/view.php?id=CVE-2014-7169
GNU Bash through 4.3 bash43-025 processes trailing strings after certain malformed function definitions in the values of environment variables, which allows remote attackers to write to files or possibly have unknown other impact via a crafted environment, as demonstrated by vectors involving the ForceCommand feature in OpenSSH sshd, the mod_cgi and mod_cgid modules in the Apache HTTP Server, scripts executed by unspecified DHCP clients, and other situations in which setting the environment occurs across a privilege boundary from Bash execution. NOTE: this vulnerability exists because of an incomplete fix for CVE-2014-6271. GNU Bash hasta 4.3 bash43-025 procesa cadenas finales después de la definición malformada de funciones en los valores de variables de entorno, lo que permite a atacantes remotos escribir hacia ficheros o posiblemente tener otro impacto desconocido a través de un entorno manipulado, tal y como se ha demostrado por vectores que involucran la característica ForceCommand en sshd OpenSSH, los módulos mod_cgi y mod_cgid en el Apache HTTP Server, scripts ejecutados por clientes DHCP no especificados, y otras situaciones en la cual establecer el entorno ocurre a través de un límite privilegiado de la ejecución de Bash. Nota: Esta vulnerabilidad existe debido a una solución incompleta para CVE-2014-6271. It was found that the fix for CVE-2014-6271 was incomplete, and Bash still allowed certain characters to be injected into other environments via specially crafted environment variables. • https://www.exploit-db.com/exploits/34777 https://www.exploit-db.com/exploits/34895 https://www.exploit-db.com/exploits/34839 https://www.exploit-db.com/exploits/36503 https://www.exploit-db.com/exploits/36504 https://www.exploit-db.com/exploits/34766 https://www.exploit-db.com/exploits/35115 https://www.exploit-db.com/exploits/36933 https://www.exploit-db.com/exploits/34765 https://www.exploit-db.com/exploits/34860 https://www.exploit-db.com/exploits/34879 • CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') CWE-228: Improper Handling of Syntactically Invalid Structure •
