A flaw was found in the "Leaf and Chain" OCSP policy implementation in JSS' CryptoManager versions after 4.4.6, 4.5.3, 4.6.0, where it implicitly trusted the root certificate of a certificate chain. Applications using this policy may not properly verify the chain and could be vulnerable to attacks such as Man in the Middle. Se detectó un fallo en la implementación de la política OCSP "Leaf and Chain" en las versiones de CryptoManager de JSS versiones posteriores a 4.4.6, 4.5.3, 4.6.0, donde confiaba implícitamente en el certificado raíz de una cadena de certificados. Es posible que las aplicaciones que utilizan esta política no verifiquen correctamente la cadena y puedan ser vulnerables a ataques de tipo Man in the Middle.

While investigating bug PROTON-2014, we discovered that under some circumstances Apache Qpid Proton versions 0.9 to 0.27.0 (C library and its language bindings) can connect to a peer anonymously using TLS *even when configured to verify the peer certificate* while used with OpenSSL versions before 1.1.0. This means that an undetected man in the middle attack could be constructed if an attacker can arrange to intercept TLS traffic. Mientras investigábamos el error PROTON-2014, descubrimos que en algunas circunstancias las versiones de Apache Qpid Proton 0.9 a 0.27.0 (librería de C y sus adaptaciones de lenguaje) pueden conectarse a un peer de forma anónima utilizando TLS *incluso cuando está configurado para verificar el certificado del peer* mientras se utiliza con versiones de OpenSSL anteriores a la 1.1.0. Esto significa que un ataque man in the middle podría ser construido si un atacante puede interceptar el tráfico TLS. A cryptographic weakness was discovered in qpid-proton's use of TLS. • http://www.openwall.com/lists/oss-security/2019/04/23/4 http://www.securityfocus.com/bid/108044 https://access.redhat.com/errata/RHSA-2019:0886 https://access.redhat.com/errata/RHSA-2019:1398 https://access.redhat.com/errata/RHSA-2019:1399 https://access.redhat.com/errata/RHSA-2019:1400 https://access.redhat.com/errata/RHSA-2019:2777 https://access.redhat.com/errata/RHSA-2019:2778 https://access.redhat.com/errata/RHSA-2019:2779 https://access.redhat.com/errata/ • CWE-300: Channel Accessible by Non-Endpoint •

glibc contains a vulnerability that allows specially crafted LD_LIBRARY_PATH values to manipulate the heap/stack, causing them to alias, potentially resulting in arbitrary code execution. Please note that additional hardening changes have been made to glibc to prevent manipulation of stack and heap memory but these issues are not directly exploitable, as such they have not been given a CVE. This affects glibc 2.25 and earlier. Glibc contiene una vulnerabilidad que permite que los valores LD_LIBRARY_PATH especialmente creados para manipular la región heap/stack de la memoria, generando entonces un alias, lo que podría conllevar a la ejecución del código arbitrario. Tenga en cuenta que se han realizado cambios de refuerzo adicionales en glibc para evitar la manipulación del stack y heap de la memoria de almacenamiento dinámico, pero estos problemas no se pueden explotar directamente, por lo que no se les ha otorgado un CVE. • https://www.exploit-db.com/exploits/42276 https://www.exploit-db.com/exploits/42274 https://www.exploit-db.com/exploits/42275 http://packetstormsecurity.com/files/154361/Cisco-Device-Hardcoded-Credentials-GNU-glibc-BusyBox.html http://seclists.org/fulldisclosure/2019/Sep/7 http://www.debian.org/security/2017/dsa-3887 http://www.securityfocus.com/bid/99127 http://www.securitytracker.com/id/1038712 https://access.redhat.com/errata/RHSA-2017:1479 https://access.redhat.com/errata/ • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

The raw_cmd_copyin function in drivers/block/floppy.c in the Linux kernel through 3.14.3 does not properly handle error conditions during processing of an FDRAWCMD ioctl call, which allows local users to trigger kfree operations and gain privileges by leveraging write access to a /dev/fd device. La función raw_cmd_copyin en drivers/block/floppy.c en el kernel de Linux hasta 3.14.3 no maneja debidamente condiciones de error durante el procesado de una llamada FDRAWCMD ioctl, lo que permite a usuarios locales provocar operaciones kfree y ganar privilegios mediante el aprovechamiento de acceso de escritura hacia un dispositivo /dev/fd. A flaw was found in the way the Linux kernel's floppy driver handled user space provided data in certain error code paths while processing FDRAWCMD IOCTL commands. A local user with write access to /dev/fdX could use this flaw to free (using the kfree() function) arbitrary kernel memory. (CVE-2014-1737, Important) It was found that the Linux kernel's floppy driver leaked internal kernel memory addresses to user space during the processing of the FDRAWCMD IOCTL command. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=ef87dbe7614341c2e7bfe8d32fcb7028cc97442c http://linux.oracle.com/errata/ELSA-2014-0771.html http://linux.oracle.com/errata/ELSA-2014-3043.html http://lists.opensuse.org/opensuse-security-announce/2014-05/msg00007.html http://lists.opensuse.org/opensuse-security-announce/2014-05/msg00012.html http://rhn.redhat.com/errata/RHSA-2014-0800.html http://rhn.redhat.com/errata/RHSA-2014-0801.html http://secunia.com • CWE-754: Improper Check for Unusual or Exceptional Conditions •

The raw_cmd_copyout function in drivers/block/floppy.c in the Linux kernel through 3.14.3 does not properly restrict access to certain pointers during processing of an FDRAWCMD ioctl call, which allows local users to obtain sensitive information from kernel heap memory by leveraging write access to a /dev/fd device.
