CVSS: 9.8EPSS: 0%CPEs: 10EXPL: 0CVE-2019-11740 – Mozilla: Memory safety bugs fixed in Firefox 69, Firefox ESR 68.1, Firefox ESR 60.9, Thunderbird 68.1, and Thunderbird 60.9
https://notcve.org/view.php?id=CVE-2019-11740
Mozilla developers and community members reported memory safety bugs present in Firefox 68, Firefox ESR 68, and Firefox 60.8. Some of these bugs showed evidence of memory corruption and we presume that with enough effort that some of these could be exploited to run arbitrary code. This vulnerability affects Firefox < 69, Thunderbird < 68.1, Thunderbird < 60.9, Firefox ESR < 60.9, and Firefox ESR < 68.1. Los desarrolladores de Mozilla y los miembros de la comunidad reportaron bugs de seguridad de la memoria presentes en Firefox versión 68, Firefox ESR versión 68 y Firefox 60.8. Algunos de estos errores mostraron evidencia de corrupción de memoria y presumimos que con suficiente esfuerzo algunos de estos podrían ser explotados para ejecutar código arbitrario. • http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00009.html http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00010.html http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00011.html http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00017.html https://bugzilla.mozilla.org/buglist.cgi?bug_id=1563133%2C1573160 https://security.gentoo.org/glsa/201911-07 https://usn.ubuntu.com/4150-1 https://www.mozilla.org/security/advisories/mfsa2019-25 https& • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') CWE-787: Out-of-bounds Write •

If hyperthreading is not disabled, a timing attack vulnerability exists, similar to previous Spectre attacks. Apple has shipped macOS 10.14.5 with an option to disable hyperthreading in applications running untrusted code in a thread through a new sysctl. Firefox now makes use of it on the main thread and any worker threads. *Note: users need to update to macOS 10.14.5 in order to take advantage of this change.*. This vulnerability affects Thunderbird < 60.7, Firefox < 67, and Firefox ESR < 60.7. • https://bugzilla.mozilla.org/show_bug.cgi?id=1546544 https://mdsattacks.com https://www.mozilla.org/security/advisories/mfsa2019-13 https://www.mozilla.org/security/advisories/mfsa2019-14 https://www.mozilla.org/security/advisories/mfsa2019-15 • CWE-203: Observable Discrepancy •

A race condition is present in the crash generation server used to generate data for the crash reporter. This issue can lead to a use-after-free in the main process, resulting in a potentially exploitable crash and a sandbox escape. *Note: this vulnerability only affects Windows. Other operating systems are unaffected.*. This vulnerability affects Thunderbird < 60.7, Firefox < 67, and Firefox ESR < 60.7. • https://bugzilla.mozilla.org/show_bug.cgi?id=1542581 https://www.mozilla.org/security/advisories/mfsa2019-13 https://www.mozilla.org/security/advisories/mfsa2019-14 https://www.mozilla.org/security/advisories/mfsa2019-15 • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') CWE-416: Use After Free •

A vulnerability exists in the Windows sandbox where an uninitialized value in memory can be leaked to a renderer from a broker when making a call to access an otherwise unavailable file. This results in the potential leaking of information stored at that memory location. *Note: this issue only occurs on Windows. Other operating systems are unaffected.*. This vulnerability affects Thunderbird < 60.7, Firefox < 67, and Firefox ESR < 60.7. • https://bugzilla.mozilla.org/show_bug.cgi?id=1534196 https://www.mozilla.org/security/advisories/mfsa2019-13 https://www.mozilla.org/security/advisories/mfsa2019-14 https://www.mozilla.org/security/advisories/mfsa2019-15 • CWE-755: Improper Handling of Exceptional Conditions CWE-908: Use of Uninitialized Resource •
CVSS: 6.5EPSS: 69%CPEs: 8EXPL: 1CVE-2019-11730 – Mozilla: Same-origin policy treats all files in a directory as having the same-origin
https://notcve.org/view.php?id=CVE-2019-11730
A vulnerability exists where if a user opens a locally saved HTML file, this file can use file: URIs to access other files in the same directory or sub-directories if the names are known or guessed. The Fetch API can then be used to read the contents of any files stored in these directories and they may uploaded to a server. It was demonstrated that in combination with a popular Android messaging app, if a malicious HTML attachment is sent to a user and they opened that attachment in Firefox, due to that app's predictable pattern for locally-saved file names, it is possible to read attachments the victim received from other correspondents. This vulnerability affects Firefox ESR < 60.8, Firefox < 68, and Thunderbird < 60.8. Se presenta una vulnerabilidad donde, si un usuario abre un archivo HTML guardado localmente, este archivo puede usar URIs file: para acceder a otros archivos en el mismo directorio o subdirectorios si los nombres son conocidos o adivinados. • https://github.com/alidnf/CVE-2019-11730 http://lists.opensuse.org/opensuse-security-announce/2019-07/msg00055.html http://lists.opensuse.org/opensuse-security-announce/2019-07/msg00058.html http://lists.opensuse.org/opensuse-security-announce/2019-08/msg00073.html http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00009.html http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00010.html https://bugzilla.mozilla.org/show_bug.cgi?id=1558299 https://lists.debian.org/debian& • CWE-829: Inclusion of Functionality from Untrusted Control Sphere •
