CVE-2020-12424 – Mozilla: WebRTC permission prompt could have been bypassed by a compromised content process
https://notcve.org/view.php?id=CVE-2020-12424
When constructing a permission prompt for WebRTC, a URI was supplied from the content process. This URI was untrusted, and could have been the URI of an origin that was previously granted permission; bypassing the prompt. This vulnerability affects Firefox < 78. Cuando se construye un aviso de permiso para WebRTC, se suministraba un URI desde el proceso de contenido. Este URI no era confiable, y podría haber sido el URI de un origen que previamente se le concediera permiso; omitiendo el aviso. • 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=1562600 https://security.gentoo.org/glsa/202007-10 https://www.mozilla.org/security/advisories/mfsa2020-24 https://access.redhat.com/security/cve/CVE-2020-12424 https://bugzilla.redhat.com/show_bug.cgi?id=1872539 • CWE-276: Incorrect Default Permissions CWE-451: User Interface (UI) Misrepresentation of Critical Information •

Mozilla developers and community members reported memory safety bugs present in Firefox 77. 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 < 78. Los desarrolladores de Mozilla y los miembros de la comunidad reportaron bugs de seguridad de la memoria presentes en Firefox versión 77. Algunos de estos errores mostraron evidencia de corrupción de la memoria y presumimos que con suficiente esfuerzo algunos de estos podrían haber sido explotados para ejecutar código arbitrario. • 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/buglist.cgi?bug_id=1608068%2C1609951%2C1631187%2C1637682 https://security.gentoo.org/glsa/202007-10 https://www.mozilla.org/security/advisories/mfsa2020-24 • CWE-787: Out-of-bounds Write •

When "%2F" was present in a manifest URL, Firefox's AppCache behavior may have become confused and allowed a manifest to be served from a subdirectory. This could cause the appcache to be used to service requests for the top level directory. This vulnerability affects Firefox < 78. Cuando "%2F" estaba presente en una URL de manifiesto, el comportamiento de AppCache de Firefox puede haber sido confundido y permitir que sea servido un manifiesto desde un subdirectorio. Esto podría hacer que el appcache sea usado para atender peticiones para el directorio de nivel superior. • 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=1586630 https://security.gentoo.org/glsa/202007-10 https://www.mozilla.org/security/advisories/mfsa2020-24 • CWE-276: Incorrect Default Permissions •

https://notcve.org/view.php?id=CVE-2020-15396
In HylaFAX+ through 7.0.2 and HylaFAX Enterprise, the faxsetup utility calls chown on files in user-owned directories. By winning a race, a local attacker could use this to escalate his privileges to root. En HylaFAX+ versiones hasta 7.0.2 y HylaFAX Enterprise, la utilidad de configuración del fax llama chown sobre archivos en directorios propiedad del usuario. Al ganar una carrera, un atacante local podría usar esto para escalar sus privilegios para root • http://lists.opensuse.org/opensuse-security-announce/2020-08/msg00039.html http://lists.opensuse.org/opensuse-security-announce/2020-08/msg00040.html http://lists.opensuse.org/opensuse-security-announce/2020-08/msg00046.html http://lists.opensuse.org/opensuse-security-announce/2020-09/msg00054.html https://bugzilla.suse.com/show_bug.cgi?id=1173521 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/J52QFVREJWJ35YSEEDDRMZQ2LM2H2WE6 https://lists.fedoraproject.org/archives/list& • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •
CVE-2017-18922 – libvncserver: websocket decoding buffer overflow
https://notcve.org/view.php?id=CVE-2017-18922
It was discovered that websockets.c in LibVNCServer prior to 0.9.12 did not properly decode certain WebSocket frames. A malicious attacker could exploit this by sending specially crafted WebSocket frames to a server, causing a heap-based buffer overflow. Se detectó que el archivo websockets.c en LibVNCServer versiones anteriores a 0.9.12, no decodificaba apropiadamente determinados tramas de WebSocket. Un atacante malicioso podría explotar esto mediante el envío de tramas de WebSocket especialmente diseñadas hacia un servidor, causando un desbordamiento del búfer en la región heap de la memoria A flaw was found in libvncserver. A heap-based buffer overflow within the websocket decoding functionality is possible, which can lead to exploitation by a malicious attacker to overwrite a function pointer. • http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00020.html http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00028.html http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00033.html http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00055.html http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00066.html http://www.openwall.com/lists/oss-security/2020/06/30/3 https://bugzilla.redhat.com/show_bug.cgi?id=1852356 https://cer • CWE-122: Heap-based Buffer Overflow CWE-787: Out-of-bounds Write •
