CVE-2018-17972 – kernel: Unprivileged users able to inspect kernel stacks of arbitrary tasks
https://notcve.org/view.php?id=CVE-2018-17972
An issue was discovered in the proc_pid_stack function in fs/proc/base.c in the Linux kernel through 4.18.11. It does not ensure that only root may inspect the kernel stack of an arbitrary task, allowing a local attacker to exploit racy stack unwinding and leak kernel task stack contents. Se descubrió un problema en la función proc_pid_stack en fs/proc/base.c en el kernel de Linux hasta la versión 4.18.11. No asegura que solo root pueda inspeccionar la pila del kernel de una tarea arbitraria, lo que permite que un atacante local explote de forma arbitraria el proceso de marcha atrás en la pila a la hora de producirse una excepción (stack unwinding) y filtre el contenido de la pila de tareas del kernel. An issue was discovered in the proc_pid_stack function in fs/proc/base.c in the Linux kernel. • http://lists.opensuse.org/opensuse-security-announce/2019-05/msg00043.html http://www.securityfocus.com/bid/105525 https://access.redhat.com/errata/RHSA-2019:0512 https://access.redhat.com/errata/RHSA-2019:0514 https://access.redhat.com/errata/RHSA-2019:0831 https://access.redhat.com/errata/RHSA-2019:2473 https://lists.debian.org/debian-lts-announce/2019/03/msg00017.html https://lists.debian.org/debian-lts-announce/2019/03/msg00034.html https://lists.debian.org/debian-lts-ann • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •
CVE-2018-12387 – Mozilla: stack out-of-bounds read in Array.prototype.push
https://notcve.org/view.php?id=CVE-2018-12387
A vulnerability where the JavaScript JIT compiler inlines Array.prototype.push with multiple arguments that results in the stack pointer being off by 8 bytes after a bailout. This leaks a memory address to the calling function which can be used as part of an exploit inside the sandboxed content process. This vulnerability affects Firefox ESR < 60.2.2 and Firefox < 62.0.3. Vulnerabilidad por la cual el compilador JIT de JavaScript inserta Array.prototype.push con múltiples argumentos que resultan en que el puntero de la pila está fuera de su sitio por 8 bytes tras un bailout. Esto filtra una dirección de memoria a la función llamante que puede emplearse como parte de un exploit dentro del proceso de contenido en sandbox. • http://www.securityfocus.com/bid/105460 http://www.securitytracker.com/id/1041770 https://access.redhat.com/errata/RHSA-2018:2881 https://access.redhat.com/errata/RHSA-2018:2884 https://bugzilla.mozilla.org/show_bug.cgi?id=1493903 https://security.gentoo.org/glsa/201810-01 https://usn.ubuntu.com/3778-1 https://www.debian.org/security/2018/dsa-4310 https://www.mozilla.org/security/advisories/mfsa2018-24 https://access.redhat.com/security/cve/CVE-2018-12387 https:/ • CWE-20: Improper Input Validation CWE-125: Out-of-bounds Read •
CVE-2018-12386 – Mozilla: type confusion in JavaScript
https://notcve.org/view.php?id=CVE-2018-12386
A vulnerability in register allocation in JavaScript can lead to type confusion, allowing for an arbitrary read and write. This leads to remote code execution inside the sandboxed content process when triggered. This vulnerability affects Firefox ESR < 60.2.2 and Firefox < 62.0.3. Una vulnerabilidad en la asignación de registros en JavaScript puede conducir a una confusión de tipos que permite la lectura y escritura arbitrarias. Esto conduce a la ejecución remota de código en el proceso de contenido en sandbox cuando se desencadena. • http://www.securityfocus.com/bid/105460 http://www.securitytracker.com/id/1041770 https://access.redhat.com/errata/RHSA-2018:2881 https://access.redhat.com/errata/RHSA-2018:2884 https://bugzilla.mozilla.org/show_bug.cgi?id=1493900 https://security.gentoo.org/glsa/201810-01 https://usn.ubuntu.com/3778-1 https://www.debian.org/security/2018/dsa-4310 https://www.mozilla.org/security/advisories/mfsa2018-24 https://access.redhat.com/security/cve/CVE-2018-12386 https:/ • CWE-704: Incorrect Type Conversion or Cast CWE-787: Out-of-bounds Write •
CVE-2018-14649 – ceph-iscsi-cli: rbd-target-api service runs in debug mode allowing for remote command execution
https://notcve.org/view.php?id=CVE-2018-14649
It was found that ceph-isci-cli package as shipped by Red Hat Ceph Storage 2 and 3 is using python-werkzeug in debug shell mode. This is done by setting debug=True in file /usr/bin/rbd-target-api provided by ceph-isci-cli package. This allows unauthenticated attackers to access this debug shell and escalate privileges. Once an attacker has successfully connected to this debug shell they will be able to execute arbitrary commands remotely. These commands will run with the same privileges as of user executing the application which is using python-werkzeug with debug shell mode enabled. • http://www.securityfocus.com/bid/105434 https://access.redhat.com/articles/3623521 https://access.redhat.com/errata/RHSA-2018:2837 https://access.redhat.com/errata/RHSA-2018:2838 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2018-14649 https://github.com/ceph/ceph-iscsi-cli/issues/120 https://github.com/ceph/ceph-iscsi-cli/pull/121/commits/c3812075e30c76a800a961e7291087d357403f6b https://access.redhat.com/security/cve/CVE-2018-14649 https://bugzilla.redhat.com/show_bug.cgi?id= • CWE-77: Improper Neutralization of Special Elements used in a Command ('Command Injection') •
