CVE-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 •
CVE-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.

The RSA-CRT implementation in the Cavium Software Development Kit (SDK) 2.x, when used on OCTEON II CN6xxx Hardware on Linux to support TLS with Perfect Forward Secrecy (PFS), makes it easier for remote attackers to obtain private RSA keys by conducting a Lenstra side-channel attack.

CVE-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 •
