CVE-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 •
CVE-2019-17024 – Mozilla: Memory safety bugs fixed in Firefox 72 and Firefox ESR 68.4
https://notcve.org/view.php?id=CVE-2019-17024
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. Algunos de estos errores mostraron evidencia de corrupción de memoria y suponemos que con un esfuerzo suficiente algunos de estos podrían haber sido explotados para ejecutar código arbitrario. • http://lists.opensuse.org/opensuse-security-announce/2020-01/msg00029.html http://lists.opensuse.org/opensuse-security-announce/2020-01/msg00043.html http://packetstormsecurity.com/files/155912/Slackware-Security-Advisory-mozilla-thunderbird-Updates.html https://access.redhat.com/errata/RHSA-2020:0085 https://access.redhat.com/errata/RHSA-2020:0086 https://access.redhat.com/errata/RHSA-2020:0111 https://access.redhat.com/errata/RHSA-2020:0120 https://access.redhat.com/errata/RHSA-2020:0123 https: • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') CWE-787: Out-of-bounds Write •
CVE-2019-19339 – kpatch: hw: incomplete fix for CVE-2018-12207
https://notcve.org/view.php?id=CVE-2019-19339
It was found that the Red Hat Enterprise Linux 8 kpatch update did not include the complete fix for CVE-2018-12207. A flaw was found in the way Intel CPUs handle inconsistency between, virtual to physical memory address translations in CPU's local cache and system software's Paging structure entries. A privileged guest user may use this flaw to induce a hardware Machine Check Error on the host processor, resulting in a severe DoS scenario by halting the processor. System software like OS OR Virtual Machine Monitor (VMM) use virtual memory system for storing program instructions and data in memory. Virtual Memory system uses Paging structures like Page Tables and Page Directories to manage system memory. • https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2019-19339 https://access.redhat.com/security/cve/CVE-2019-19339 https://bugzilla.redhat.com/show_bug.cgi?id=1782199 • CWE-805: Buffer Access with Incorrect Length Value •
CVE-2019-16777 – Arbitrary File Overwrite in npm CLI
https://notcve.org/view.php?id=CVE-2019-16777
Versions of the npm CLI prior to 6.13.4 are vulnerable to an Arbitrary File Overwrite. It fails to prevent existing globally-installed binaries to be overwritten by other package installations. For example, if a package was installed globally and created a serve binary, any subsequent installs of packages that also create a serve binary would overwrite the previous serve binary. This behavior is still allowed in local installations and also through install scripts. This vulnerability bypasses a user using the --ignore-scripts install option. • http://lists.opensuse.org/opensuse-security-announce/2020-01/msg00027.html https://access.redhat.com/errata/RHEA-2020:0330 https://access.redhat.com/errata/RHSA-2020:0573 https://access.redhat.com/errata/RHSA-2020:0579 https://access.redhat.com/errata/RHSA-2020:0597 https://access.redhat.com/errata/RHSA-2020:0602 https://blog.npmjs.org/post/189618601100/binary-planting-with-the-npm-cli https://github.com/npm/cli/security/advisories/GHSA-4328-8hgf-7wjr https://lists.fedoraproject • CWE-20: Improper Input Validation CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') CWE-269: Improper Privilege Management •
