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-2019-11884 – kernel: sensitive information disclosure from kernel stack memory via HIDPCONNADD command
https://notcve.org/view.php?id=CVE-2019-11884
The do_hidp_sock_ioctl function in net/bluetooth/hidp/sock.c in the Linux kernel before 5.0.15 allows a local user to obtain potentially sensitive information from kernel stack memory via a HIDPCONNADD command, because a name field may not end with a '\0' character. La función do_hidp_sock_ioctl en net/bluetooth/hidp/sock.c en el kernel de Linux, versiones anteriores a 5.0.15, permite a un usuario local obtener información potencialmente sensible de la memoria de la pila del kernel a través de un comando HIDPCONNNADD, ya que un campo de nombre puede no terminar con un carácter ` \0'. A flaw was found in the Linux kernel's implementation of the Bluetooth Human Interface Device Protocol (HIDP). A local attacker with access permissions to the Bluetooth device can issue an IOCTL which will trigger the do_hidp_sock_ioctl function in net/bluetooth/hidp/sock.c.c. This function can leak potentially sensitive information from the kernel stack memory via a HIDPCONNADD command because a name field may not be correctly NULL terminated. • http://lists.opensuse.org/opensuse-security-announce/2019-05/msg00037.html http://lists.opensuse.org/opensuse-security-announce/2019-05/msg00043.html http://lists.opensuse.org/opensuse-security-announce/2019-05/msg00071.html http://www.securityfocus.com/bid/108299 https://access.redhat.com/errata/RHSA-2019:3309 https://access.redhat.com/errata/RHSA-2019:3517 https://access.redhat.com/errata/RHSA-2020:0740 https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.0.15 https://g • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
