CVSS: 5.5EPSS: 0%CPEs: 35EXPL: 1CVE-2019-7222 – Kernel: KVM: leak of uninitialized stack contents to guest
https://notcve.org/view.php?id=CVE-2019-7222
The KVM implementation in the Linux kernel through 4.20.5 has an Information Leak. La implementación KVM en el kernel de Linux, hasta la versión 4.20.5, tiene una fuga de información. An information leakage issue was found in the way Linux kernel's KVM hypervisor handled page fault exceptions while emulating instructions like VMXON, VMCLEAR, VMPTRLD, and VMWRITE with memory address as an operand. It occurs if the operand is a mmio address, as the returned exception object holds uninitialized stack memory contents. A guest user/process could use this flaw to leak host's stack memory contents to a guest. • http://lists.opensuse.org/opensuse-security-announce/2019-02/msg00042.html http://packetstormsecurity.com/files/151712/KVM-kvm_inject_page_fault-Uninitialized-Memory-Leak.html http://www.openwall.com/lists/oss-security/2019/02/18/2 http://www.securityfocus.com/bid/106963 https://access.redhat.com/errata/RHSA-2019:2029 https://access.redhat.com/errata/RHSA-2019:2043 https://access.redhat.com/errata/RHSA-2019:3309 https://access.redhat.com/errata/RHSA-2019:3517 https://bugs.chromiu • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

https://notcve.org/view.php?id=CVE-2019-7664
In elfutils 0.175, a negative-sized memcpy is attempted in elf_cvt_note in libelf/note_xlate.h because of an incorrect overflow check. Crafted elf input causes a segmentation fault, leading to denial of service (program crash). En elfutils 0.175, se intenta realizar un memcpy de tamaño negativo en elf_cvt_note en libelf/note_xlate.h debido a una comprobación de desbordamiento incorrecta. Las entradas elf manipuladas provocan un fallo de segmentación, que conduce a una denegación de servicio (cierre inesperado del programa). • https://access.redhat.com/errata/RHSA-2019:2197 https://access.redhat.com/errata/RHSA-2019:3575 https://sourceware.org/bugzilla/show_bug.cgi?id=24084 https://access.redhat.com/security/cve/CVE-2019-7664 https://bugzilla.redhat.com/show_bug.cgi?id=1677536 • CWE-787: Out-of-bounds Write •

In elfutils 0.175, a heap-based buffer over-read was discovered in the function elf32_xlatetom in elf32_xlatetom.c in libelf. A crafted ELF input can cause a segmentation fault leading to denial of service (program crash) because ebl_core_note does not reject malformed core file notes. En elfutils 0.175, existe una sobrelectura de búfer basada en memoria dinámica (heap) en la función elf32_xlatetom en elf32_xlatetom.c.

https://notcve.org/view.php?id=CVE-2019-7310
In Poppler 0.73.0, a heap-based buffer over-read (due to an integer signedness error in the XRef::getEntry function in XRef.cc) allows remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via a crafted PDF document, as demonstrated by pdftocairo. En la versión 0.73.0 de Poppler, una sobrelectura de búfer (debido a un error en la propiedad signedness de un número entero en la función XRef::getEntry function en XRef.cc) basada en memoria dinámica (heap) permite a los atacantes remotos causar una denegación de servicio (cierre inesperado de la aplicación) o, potencialmente, otro impacto no especificado mediante un documento PDF manipulado, tal y como queda demostrado con pdftocairo. • http://www.securityfocus.com/bid/106829 https://access.redhat.com/errata/RHSA-2019:2022 https://access.redhat.com/errata/RHSA-2019:2713 https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=12797 https://gitlab.freedesktop.org/poppler/poppler/issues/717 https://lists.debian.org/debian-lts-announce/2019/03/msg00008.html https://lists.debian.org/debian-lts-announce/2020/11/msg00014.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/BI7NLDN2 • CWE-125: Out-of-bounds Read CWE-681: Incorrect Conversion between Numeric Types •
