CVSS: 7.0EPSS: 0%CPEs: 17EXPL: 0CVE-2019-12817 – kernel: ppc: unrelated processes being able to read/write to each other's virtual memory
https://notcve.org/view.php?id=CVE-2019-12817
arch/powerpc/mm/mmu_context_book3s64.c in the Linux kernel before 5.1.15 for powerpc has a bug where unrelated processes may be able to read/write to one another's virtual memory under certain conditions via an mmap above 512 TB. Only a subset of powerpc systems are affected. En el archivo arch/powerpc/mm/mmu_context_book3s64.c en el kernel de Linux anterior a versión 5.1.15 para powerpc, presenta un error (bug) por el cual procesos no relacionados pueden leer y escribir en la memoria virtual de otros bajo ciertas condiciones por medio de un mmap superior a 512 TB. Sólo un subconjunto de sistemas powerpc están afectados. A flaw was found in the way the Linux kernel's memory subsystem on certain 64-bit PowerPCs with the hash page table MMU handled memory above 512TB. • http://lists.opensuse.org/opensuse-security-announce/2019-07/msg00025.html http://www.openwall.com/lists/oss-security/2019/06/24/5 http://www.securityfocus.com/bid/108884 https://access.redhat.com/errata/RHSA-2019:2703 https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.1.15 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=ca72d88378b2f2444d3ec145dd442d449d3fefbc https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/messag • CWE-787: Out-of-bounds Write •

https://notcve.org/view.php?id=CVE-2019-10168
The virConnectBaselineHypervisorCPU() and virConnectCompareHypervisorCPU() libvirt APIs, 4.x.x before 4.10.1 and 5.x.x before 5.4.1, accept an "emulator" argument to specify the program providing emulation for a domain. Since v1.2.19, libvirt will execute that program to probe the domain's capabilities. Read-only clients could specify an arbitrary path for this argument, causing libvirtd to execute a crafted executable with its own privileges. Las APIs libvirt de las funciones virConnectBaselineHypervisorCPU() y virConnectCompareHypervisorCPU(), versiones 4.x.x anteriores a 4.10.1 y versiones 5.x.x anteriores a 5.4.1, aceptan un argumento "emulator" para especificar el programa que proporciona emulación para un dominio. Desde versión v1.2.19, libvirt ejecutará ese programa para examinar las capacidades del dominio. • https://access.redhat.com/libvirt-privesc-vulnerabilities https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2019-10168 https://security.gentoo.org/glsa/202003-18 https://access.redhat.com/security/cve/CVE-2019-10168 https://bugzilla.redhat.com/show_bug.cgi?id=1720118 • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') CWE-250: Execution with Unnecessary Privileges CWE-284: Improper Access Control •
CVSS: 7.8EPSS: 0%CPEs: 14EXPL: 0CVE-2019-10166 – libvirt: virDomainManagedSaveDefineXML API exposed to readonly clients
https://notcve.org/view.php?id=CVE-2019-10166
It was discovered that libvirtd, versions 4.x.x before 4.10.1 and 5.x.x before 5.4.1, would permit readonly clients to use the virDomainManagedSaveDefineXML() API, which would permit them to modify managed save state files. If a managed save had already been created by a privileged user, a local attacker could modify this file such that libvirtd would execute an arbitrary program when the domain was resumed. Se detectó que libvirtd, versiones 4.x.x anteriores a 4.10.1 y versiones 5.x.x anteriores a 5.4.1, permitiría a los clientes de solo lectura utilizar la API de la función virDomainManagedSaveDefineXML(), lo que les permitiría modificar archivos de estado managed save. Si un managed save ya ha sido creado por un usuario privilegiado, un atacante local podría modificar este archivo de manera que libvirtd ejecutaría un programa arbitrario cuando el dominio esté reanudado.

When using the gdImageCreateFromXbm() function in the GD Graphics Library (aka LibGD) 2.2.5, as used in the PHP GD extension in PHP versions 7.1.x below 7.1.30, 7.2.x below 7.2.19 and 7.3.x below 7.3.6, it is possible to supply data that will cause the function to use the value of uninitialized variable. This may lead to disclosing contents of the stack that has been left there by previous code. Cuando se usa la función gdImageCreateFromXbm () en la Biblioteca de gráficos GD (también conocida como LibGD) 2.2.5, como se usa en la extensión PHP GD en las versiones de PHP 7.1.x debajo de 7.1.30, 7.2.x debajo de 7.2.19 y 7.3.x debajo 7.3.6, es posible suministrar datos que harán que la función use el valor de la variable no inicializada.
