CVE-2019-10160 – python: regression of CVE-2019-9636 due to functional fix to allow port numbers in netloc
https://notcve.org/view.php?id=CVE-2019-10160
A security regression of CVE-2019-9636 was discovered in python since commit d537ab0ff9767ef024f26246899728f0116b1ec3 affecting versions 2.7, 3.5, 3.6, 3.7 and from v3.8.0a4 through v3.8.0b1, which still allows an attacker to exploit CVE-2019-9636 by abusing the user and password parts of a URL. When an application parses user-supplied URLs to store cookies, authentication credentials, or other kind of information, it is possible for an attacker to provide specially crafted URLs to make the application locate host-related information (e.g. cookies, authentication data) and send them to a different host than where it should, unlike if the URLs had been correctly parsed. The result of an attack may vary based on the application. Se descubrió una regresión de seguridad de CVE-2019-9636 en python desde commit con ID d537ab0ff9767ef024f26246899728f0116b1ec3 que afecta a las versiones 2.7, 3.5, 3.6, 3.7 y de v3.8.0a4 a v3.8.0b1, el cual permite a un atacante explotar CVE-2019-9636 violando las partes usuario (user) y contraseña (password) de una URL. Cuando una aplicación analiza las URL proporcionadas por el usuario para almacenar cookies, credenciales de autenticación u otro tipo de información, es posible que un atacante proporcione URL especialmente creadas para que la aplicación ubique información relacionada con el host (por ejemplo, cookies, datos de autenticación) y envíe a un host diferente al que debería, a diferencia de si las URL se analizaron correctamente. • http://lists.opensuse.org/opensuse-security-announce/2019-08/msg00042.html http://lists.opensuse.org/opensuse-security-announce/2020-01/msg00040.html https://access.redhat.com/errata/RHSA-2019:1587 https://access.redhat.com/errata/RHSA-2019:1700 https://access.redhat.com/errata/RHSA-2019:2437 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2019-10160 https://github.com/python/cpython/commit/250b62acc59921d399f0db47db3b462cd6037e09 https://github.com/python/cpython/commit/8d0ef0b5edeae52960c7ed05ae8a12388324f87e • CWE-172: Encoding Error CWE-522: Insufficiently Protected Credentials •
CVE-2019-11833 – kernel: fs/ext4/extents.c leads to information disclosure
https://notcve.org/view.php?id=CVE-2019-11833
fs/ext4/extents.c in the Linux kernel through 5.1.2 does not zero out the unused memory region in the extent tree block, which might allow local users to obtain sensitive information by reading uninitialized data in the filesystem. fs / ext4 / extents.c en el kernel de Linux hasta 5.1.2 no pone a cero la región de memoria no utilizada en el bloque del árbol de extensión, lo que podría permitir a los usuarios locales obtener información confidencial al leer datos no inicializados en el sistema de archivos. A flaw was found in the Linux kernel's implementation of ext4 extent management. The kernel doesn't correctly initialize memory regions in the extent tree block which may be exported to a local user to obtain sensitive information by reading empty/uninitialized data from the filesystem. • http://lists.opensuse.org/opensuse-security-announce/2019-05/msg00071.html http://lists.opensuse.org/opensuse-security-announce/2019-06/msg00039.html http://lists.opensuse.org/opensuse-security-announce/2019-06/msg00048.html http://packetstormsecurity.com/files/154951/Kernel-Live-Patch-Security-Notice-LSN-0058-1.html http://www.securityfocus.com/bid/108372 https://access.redhat.com/errata/RHSA-2019:2029 https://access.redhat.com/errata/RHSA-2019:2043 https://access.redhat.com/errata/RHSA-2019 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-908: Use of Uninitialized Resource •
CVE-2019-6470 – dhcpd: use-after-free error leads crash in IPv6 mode when using mismatched BIND libraries
https://notcve.org/view.php?id=CVE-2019-6470
There had existed in one of the ISC BIND libraries a bug in a function that was used by dhcpd when operating in DHCPv6 mode. There was also a bug in dhcpd relating to the use of this function per its documentation, but the bug in the library function prevented this from causing any harm. All releases of dhcpd from ISC contain copies of this, and other, BIND libraries in combinations that have been tested prior to release and are known to not present issues like this. Some third-party packagers of ISC software have modified the dhcpd source, BIND source, or version matchup in ways that create the crash potential. Based on reports available to ISC, the crash probability is large and no analysis has been done on how, or even if, the probability can be manipulated by an attacker. • https://access.redhat.com/errata/RHSA-2019:2060 https://access.redhat.com/errata/RHSA-2019:3525 https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=896122 https://lists.opensuse.org/opensuse-security-announce/2019-10/msg00048.html https://lists.opensuse.org/opensuse-security-announce/2019-10/msg00049.html https://access.redhat.com/security/cve/CVE-2019-6470 https://bugzilla.redhat.com/show_bug.cgi?id=1708641 • CWE-20: Improper Input Validation •
CVE-2019-11811 – kernel: use-after-free in drivers/char/ipmi/ipmi_si_intf.c, ipmi_si_mem_io.c, ipmi_si_port_io.c
https://notcve.org/view.php?id=CVE-2019-11811
An issue was discovered in the Linux kernel before 5.0.4. There is a use-after-free upon attempted read access to /proc/ioports after the ipmi_si module is removed, related to drivers/char/ipmi/ipmi_si_intf.c, drivers/char/ipmi/ipmi_si_mem_io.c, and drivers/char/ipmi/ipmi_si_port_io.c. Fue descubierto en un fallo en el kernel de Linux anterior a 5.0.4.
