CVSS: 8.1EPSS: 0%CPEs: 3EXPL: 0CVE-2021-23981 – Mozilla: Texture upload into an unbound backing buffer resulted in an out-of-bound read
https://notcve.org/view.php?id=CVE-2021-23981
A texture upload of a Pixel Buffer Object could have confused the WebGL code to skip binding the buffer used to unpack it, resulting in memory corruption and a potentially exploitable information leak or crash. This vulnerability affects Firefox ESR < 78.9, Firefox < 87, and Thunderbird < 78.9. Una carga de textura de un Objeto de Búfer de Píxeles podría haber confundido el código WebGL para omitir el enlace del búfer usado para descomprimirlo, resultando en la corrupción de la memoria y una filtración o bloqueo de información potencialmente explotable. Esta vulnerabilidad afecta a Firefox ESR versión 78.9, Firefox versiones anteriores a 87, and Thunderbird versiones anteriores a 78.9. The Mozilla Foundation Security Advisory describes this issue as: A texture upload of a Pixel Buffer Object could have confused the WebGL code to skip binding the buffer used to unpack it, resulting in memory corruption and a potentially exploitable information leak or crash. • https://bugzilla.mozilla.org/show_bug.cgi?id=1692832 https://www.mozilla.org/security/advisories/mfsa2021-10 https://www.mozilla.org/security/advisories/mfsa2021-11 https://www.mozilla.org/security/advisories/mfsa2021-12 https://access.redhat.com/security/cve/CVE-2021-23981 https://bugzilla.redhat.com/show_bug.cgi?id=1942783 • CWE-125: Out-of-bounds Read CWE-787: Out-of-bounds Write •

https://notcve.org/view.php?id=CVE-2021-23982
Using techniques that built on the slipstream research, a malicious webpage could have scanned both an internal network's hosts as well as services running on the user's local machine utilizing WebRTC connections. This vulnerability affects Firefox ESR < 78.9, Firefox < 87, and Thunderbird < 78.9. Usando técnicas que se basaron en la investigación de slipstream, una página web maliciosa podría haber escaneado tanto los hosts de una red interna como los servicios que se ejecutan en la máquina local del usuario usando conexiones WebRTC. Esta vulnerabilidad afecta a Firefox ESR versiones anteriores a 78.9, Firefox versiones anteriores a 87, y Thunderbird versiones anteriores a 78.9 • https://bugzilla.mozilla.org/show_bug.cgi?id=1677046 https://www.mozilla.org/security/advisories/mfsa2021-10 https://www.mozilla.org/security/advisories/mfsa2021-11 https://www.mozilla.org/security/advisories/mfsa2021-12 https://access.redhat.com/security/cve/CVE-2021-23982 https://bugzilla.redhat.com/show_bug.cgi?id=1942785 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-326: Inadequate Encryption Strength •

https://notcve.org/view.php?id=CVE-2021-23987
Mozilla developers and community members reported memory safety bugs present in Firefox 86 and Firefox ESR 78.8. 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 < 78.9, Firefox < 87, and Thunderbird < 78.9. Los desarrolladores y miembros de la comunidad de Mozilla informaron de fallos de seguridad de memoria presentes en Firefox 86 y Firefox ESR 78.8. Algunos de estos fallos mostraban evidencias de corrupción de memoria y suponemos que con suficiente esfuerzo algunos de ellos podrían haber sido explotados para ejecutar código arbitrario. • https://bugzilla.mozilla.org/buglist.cgi?bug_id=1513519%2C1683439%2C1690169%2C1690718 https://www.mozilla.org/security/advisories/mfsa2021-10 https://www.mozilla.org/security/advisories/mfsa2021-11 https://www.mozilla.org/security/advisories/mfsa2021-12 https://access.redhat.com/security/cve/CVE-2021-23987 https://bugzilla.redhat.com/show_bug.cgi?id=1942787 • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') CWE-787: Out-of-bounds Write •
CVSS: 4.3EPSS: 0%CPEs: 5EXPL: 0CVE-2021-23968 – Mozilla: Content Security Policy violation report could have contained the destination of a redirect
https://notcve.org/view.php?id=CVE-2021-23968
If Content Security Policy blocked frame navigation, the full destination of a redirect served in the frame was reported in the violation report; as opposed to the original frame URI. This could be used to leak sensitive information contained in such URIs. This vulnerability affects Firefox < 86, Thunderbird < 78.8, and Firefox ESR < 78.8. Si la Política de Seguridad de Contenido bloqueaba la navegación de tramas, el destino completo de un redireccionamiento servido en la trama se reportaba en el informe de infracción; a diferencia del URI de la trama original. Esto podría ser usado para filtrar información confidencial contenida en dichos URI. • https://bugzilla.mozilla.org/show_bug.cgi?id=1687342 https://lists.debian.org/debian-lts-announce/2021/03/msg00000.html https://security.gentoo.org/glsa/202104-09 https://security.gentoo.org/glsa/202104-10 https://www.debian.org/security/2021/dsa-4866 https://www.mozilla.org/security/advisories/mfsa2021-07 https://www.mozilla.org/security/advisories/mfsa2021-08 https://www.mozilla.org/security/advisories/mfsa2021-09 https://access.redhat.com/security/cve/CVE-2021-23968 https:&# • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-209: Generation of Error Message Containing Sensitive Information •
CVSS: 4.3EPSS: 0%CPEs: 5EXPL: 0CVE-2021-23969 – Mozilla: Content Security Policy violation report could have contained the destination of a redirect
https://notcve.org/view.php?id=CVE-2021-23969
As specified in the W3C Content Security Policy draft, when creating a violation report, "User agents need to ensure that the source file is the URL requested by the page, pre-redirects. If that’s not possible, user agents need to strip the URL down to an origin to avoid unintentional leakage." Under certain types of redirects, Firefox incorrectly set the source file to be the destination of the redirects. This was fixed to be the redirect destination's origin. This vulnerability affects Firefox < 86, Thunderbird < 78.8, and Firefox ESR < 78.8. • https://bugzilla.mozilla.org/show_bug.cgi?id=1542194 https://lists.debian.org/debian-lts-announce/2021/03/msg00000.html https://security.gentoo.org/glsa/202104-09 https://security.gentoo.org/glsa/202104-10 https://www.debian.org/security/2021/dsa-4866 https://www.mozilla.org/security/advisories/mfsa2021-07 https://www.mozilla.org/security/advisories/mfsa2021-08 https://www.mozilla.org/security/advisories/mfsa2021-09 https://access.redhat.com/security/cve/CVE-2021-23969 https:&# • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
