A VideoStreamEncoder may have been freed in a race condition with VideoBroadcaster::AddOrUpdateSink, resulting in a use-after-free, memory corruption, and a potentially exploitable crash. This vulnerability affects Firefox < 78. Un VideoStreamEncoder puede haberse liberado en una condición de carrera con la función VideoBroadcaster::AddOrUpdateSink, resultando en un uso de la memoria previamente liberada, una corrupción de la memoria y un bloqueo potencialmente explotable. Esta vulnerabilidad afecta a Firefox versiones anteriores a 78 • http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00027.html http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00049.html https://bugzilla.mozilla.org/show_bug.cgi?id=1639734 https://security.gentoo.org/glsa/202007-10 https://www.mozilla.org/security/advisories/mfsa2020-24 • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') CWE-416: Use After Free •

CVSS: 4.4EPSS: 0%CPEs: 4EXPL: 1CVE-2020-15095 – Sensitive information exposure through logs in npm cli
https://notcve.org/view.php?id=CVE-2020-15095
Versions of the npm CLI prior to 6.14.6 are vulnerable to an information exposure vulnerability through log files. The CLI supports URLs like "<protocol>://[<user>[:<password>]@]<hostname>[:<port>][:][/]<path>". The password value is not redacted and is printed to stdout and also to any generated log files. Las versiones de la CLI npm anteriores a 6.14.6, son susceptibles a una vulnerabilidad de exposición de información por medio de archivos de registro. La CLI admite las URL como "://[[:]@][:][:][/]". • https://github.com/ossf-cve-benchmark/CVE-2020-15095 http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00011.html http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00015.html http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00023.html https://github.com/npm/cli/blob/66aab417f836a901f8afb265251f761bb0422463/CHANGELOG.md#6146-2020-07-07 https://github.com/npm/cli/commit/a9857b8f6869451ff058789c4631fadfde5bbcbc https://github.com/npm/cli/security/advisories/GHSA-93f3-23rq- • CWE-532: Insertion of Sensitive Information into Log File •
CVSS: 7.8EPSS: 0%CPEs: 6EXPL: 0CVE-2020-15567
https://notcve.org/view.php?id=CVE-2020-15567
An issue was discovered in Xen through 4.13.x, allowing Intel guest OS users to gain privileges or cause a denial of service because of non-atomic modification of a live EPT PTE. When mapping guest EPT (nested paging) tables, Xen would in some circumstances use a series of non-atomic bitfield writes. Depending on the compiler version and optimisation flags, Xen might expose a dangerous partially written PTE to the hardware, which an attacker might be able to race to exploit. A guest administrator or perhaps even an unprivileged guest user might be able to cause denial of service, data corruption, or privilege escalation. Only systems using Intel CPUs are vulnerable. • http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00024.html http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00031.html http://www.openwall.com/lists/oss-security/2020/07/07/6 http://xenbits.xen.org/xsa/advisory-328.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/MXESCOVI7AVRNC7HEAMFM7PMEO6D3AUH https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/VB3QJJZV23Z2IDYEMIHELWYSQBUEW6JP https://security.ge • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •

https://notcve.org/view.php?id=CVE-2020-15565
An issue was discovered in Xen through 4.13.x, allowing x86 Intel HVM guest OS users to cause a host OS denial of service or possibly gain privileges because of insufficient cache write-back under VT-d. When page tables are shared between IOMMU and CPU, changes to them require flushing of both TLBs. Furthermore, IOMMUs may be non-coherent, and hence prior to flushing IOMMU TLBs, a CPU cache also needs writing back to memory after changes were made. Such writing back of cached data was missing in particular when splitting large page mappings into smaller granularity ones. A malicious guest may be able to retain read/write DMA access to frames returned to Xen's free pool, and later reused for another purpose. • http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00024.html http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00031.html http://www.openwall.com/lists/oss-security/2020/07/07/4 http://xenbits.xen.org/xsa/advisory-321.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/MXESCOVI7AVRNC7HEAMFM7PMEO6D3AUH https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/VB3QJJZV23Z2IDYEMIHELWYSQBUEW6JP https://security.ge • CWE-400: Uncontrolled Resource Consumption •
