CVSS: 8.1EPSS: 0%CPEs: 23EXPL: 1CVE-2020-6851 – openjpeg: Heap-based buffer overflow in opj_t1_clbl_decode_processor()
https://notcve.org/view.php?id=CVE-2020-6851
OpenJPEG through 2.3.1 has a heap-based buffer overflow in opj_t1_clbl_decode_processor in openjp2/t1.c because of lack of opj_j2k_update_image_dimensions validation. OpenJPEG hasta la versión 2.3.1 tiene un desbordamiento de búfer basado en almacenamiento dinámico en opj_t1_clbl_decode_processor en openjp2 / t1.c debido a la falta de validación de opj_j2k_update_image_dimensions. A heap-based buffer overflow flaw was found in openjpeg in the opj_t1_clbl_decode_processor in libopenjp2.so. Affecting versions through 2.3.1, the highest threat from this vulnerability is to file confidentiality and integrity as well as system availability. • https://access.redhat.com/errata/RHSA-2020:0262 https://access.redhat.com/errata/RHSA-2020:0274 https://access.redhat.com/errata/RHSA-2020:0296 https://github.com/uclouvain/openjpeg/issues/1228 https://lists.debian.org/debian-lts-announce/2020/01/msg00025.html https://lists.debian.org/debian-lts-announce/2020/07/msg00008.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/LACIIDDCKZJEPKTTFILSOSBQL7L3FC6V https://lists.fedoraproject.org/archives/list/pa • CWE-122: Heap-based Buffer Overflow CWE-787: Out-of-bounds Write •
CVSS: 6.1EPSS: 0%CPEs: 3EXPL: 2CVE-2019-19332 – Kernel: kvm: OOB memory write via kvm_dev_ioctl_get_cpuid
https://notcve.org/view.php?id=CVE-2019-19332
An out-of-bounds memory write issue was found in the Linux Kernel, version 3.13 through 5.4, in the way the Linux kernel's KVM hypervisor handled the 'KVM_GET_EMULATED_CPUID' ioctl(2) request to get CPUID features emulated by the KVM hypervisor. A user or process able to access the '/dev/kvm' device could use this flaw to crash the system, resulting in a denial of service. Se encontró un problema de escritura de memoria fuera de límites en el kernel de Linux, versiones 3.13 hasta 5.4, en la manera en que el hipervisor KVM del kernel de Linux manejó la petición "KVM_GET_EMULATED_CPUID" ioctl(2) para obtener las funcionalidades de CPUID emuladas por el hipervisor KVM. Un usuario o proceso capaz de acceder al dispositivo "/dev/kvm" podría usar este fallo para bloquear el sistema, resultando en una denegación de servicio.

Mozilla developers reported memory safety bugs present in Firefox 71 and Firefox ESR 68.3. Some of these bugs showed evidence of memory corruption and we presume that with enough effort some of these could have been exploited to run arbitrary code. This vulnerability affects Firefox ESR < 68.4 and Firefox < 72. Los desarrolladores de Mozilla reportaron bugs de seguridad de memoria presentes en Firefox versión 71 y Firefox ESR versión 68.3.

CVSS: 6.1EPSS: 0%CPEs: 17EXPL: 0CVE-2019-17022 – Mozilla: CSS sanitization does not escape HTML tags
https://notcve.org/view.php?id=CVE-2019-17022
When pasting a <style> tag from the clipboard into a rich text editor, the CSS sanitizer does not escape < and > characters. Because the resulting string is pasted directly into the text node of the element this does not result in a direct injection into the webpage; however, if a webpage subsequently copies the node's innerHTML, assigning it to another innerHTML, this would result in an XSS vulnerability. Two WYSIWYG editors were identified with this behavior, more may exist. This vulnerability affects Firefox ESR < 68.4 and Firefox < 72.
