CVE-2019-15030 – kernel: powerpc: local user can read vector registers of other users' processes via a Facility Unavailable exception
https://notcve.org/view.php?id=CVE-2019-15030
In the Linux kernel through 5.2.14 on the powerpc platform, a local user can read vector registers of other users' processes via a Facility Unavailable exception. To exploit the venerability, a local user starts a transaction (via the hardware transactional memory instruction tbegin) and then accesses vector registers. At some point, the vector registers will be corrupted with the values from a different local Linux process because of a missing arch/powerpc/kernel/process.c check. En el kernel de Linux versiones hasta 5.2.14 en la plataforma powerpc, un usuario local puede leer registros vectoriales de los procesos de otros usuarios por medio de una excepción Facility Unavailable. Para explotar la venerabilidad, un usuario local inicia una transacción (por medio de la instrucción de memoria transaccional de hardware tbegin) y entonces accede a los registros vectoriales. • http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00064.html http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00066.html http://www.openwall.com/lists/oss-security/2019/09/10/3 https://access.redhat.com/errata/RHSA-2020:0740 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=8205d5d98ef7f155de211f5e2eb6ca03d95a5a60 https://security.netapp.com/advisory/ntap-20191004-0001 https://usn.ubuntu.com/4135-1 https://usn.ubuntu.com/4135-2& • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-862: Missing Authorization •

CVE-2019-9854 – Unsafe URL assembly flaw in allowed script location check
https://notcve.org/view.php?id=CVE-2019-9854
LibreOffice has a feature where documents can specify that pre-installed macros can be executed on various script events such as mouse-over, document-open etc. Access is intended to be restricted to scripts under the share/Scripts/python, user/Scripts/python sub-directories of the LibreOffice install. Protection was added, to address CVE-2019-9852, to avoid a directory traversal attack where scripts in arbitrary locations on the file system could be executed by employing a URL encoding attack to defeat the path verification step. However this protection could be bypassed by taking advantage of a flaw in how LibreOffice assembled the final script URL location directly from components of the passed in path as opposed to solely from the sanitized output of the path verification step. This issue affects: Document Foundation LibreOffice 6.2 versions prior to 6.2.7; 6.3 versions prior to 6.3.1. • http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00067.html http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00055.html https://bugzilla.redhat.com/show_bug.cgi?id=1769907 https://lists.debian.org/debian-lts-announce/2019/10/msg00005.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/XQKKOIY2DMZCXJINOLIQXD2NWISDKK3N https://seclists.org/bugtraq/2019/Sep/17 https://usn.ubuntu.com/4138-1 https://www.debian.org/security/201 • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') CWE-284: Improper Access Control •
