CVE-2018-12364 – Mozilla: CSRF attacks through 307 redirects and NPAPI plugins
https://notcve.org/view.php?id=CVE-2018-12364
NPAPI plugins, such as Adobe Flash, can send non-simple cross-origin requests, bypassing CORS by making a same-origin POST that does a 307 redirect to the target site. This allows for a malicious site to engage in cross-site request forgery (CSRF) attacks. This vulnerability affects Thunderbird < 60, Thunderbird < 52.9, Firefox ESR < 60.1, Firefox ESR < 52.9, and Firefox < 61. Los plugins NPAPI, como Adobe Flash, pueden enviar peticiones cross-origin, omitiendo CORS al hacer un POST same-origin que realiza una redirección 307 al sitio objetivo. Esto permite que un sitio malicioso se vea envuelto en ataques Cross-Site Request Forgery (CSRF). • http://www.securityfocus.com/bid/104560 http://www.securitytracker.com/id/1041193 https://access.redhat.com/errata/RHSA-2018:2112 https://access.redhat.com/errata/RHSA-2018:2113 https://access.redhat.com/errata/RHSA-2018:2251 https://access.redhat.com/errata/RHSA-2018:2252 https://bugzilla.mozilla.org/show_bug.cgi?id=1436241 https://lists.debian.org/debian-lts-announce/2018/06/msg00014.html https://lists.debian.org/debian-lts-announce/2018/07/msg00013.html https://securi • CWE-352: Cross-Site Request Forgery (CSRF) CWE-829: Inclusion of Functionality from Untrusted Control Sphere •
CVE-2018-12362 – Mozilla: Integer overflow in SSSE3 scaler
https://notcve.org/view.php?id=CVE-2018-12362
An integer overflow can occur during graphics operations done by the Supplemental Streaming SIMD Extensions 3 (SSSE3) scaler, resulting in a potentially exploitable crash. This vulnerability affects Thunderbird < 60, Thunderbird < 52.9, Firefox ESR < 60.1, Firefox ESR < 52.9, and Firefox < 61. Puede ocurrir un desbordamiento de enteros durante las operaciones de gráficos realizadas por el escalador SSSE3 (Supplemental Streaming SIMD Extensions 3), lo que resulta en un cierre inesperado potencialmente explotable. La vulnerabilidad afecta a Thunderbird en versiones anteriores a la 60 y la 52.9, Firefox ESR en versiones anteriores a la 60.1 y la 52.9 y Firefox en versiones anteriores a la 61. • http://www.securityfocus.com/bid/104560 http://www.securitytracker.com/id/1041193 https://access.redhat.com/errata/RHSA-2018:2112 https://access.redhat.com/errata/RHSA-2018:2113 https://access.redhat.com/errata/RHSA-2018:2251 https://access.redhat.com/errata/RHSA-2018:2252 https://bugzilla.mozilla.org/show_bug.cgi?id=1452375 https://lists.debian.org/debian-lts-announce/2018/06/msg00014.html https://lists.debian.org/debian-lts-announce/2018/07/msg00013.html https://securi • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') CWE-190: Integer Overflow or Wraparound •
CVE-2018-12359 – Mozilla: Buffer overflow using computed size of canvas element
https://notcve.org/view.php?id=CVE-2018-12359
A buffer overflow can occur when rendering canvas content while adjusting the height and width of the canvas element dynamically, causing data to be written outside of the currently computed boundaries. This results in a potentially exploitable crash. This vulnerability affects Thunderbird < 60, Thunderbird < 52.9, Firefox ESR < 60.1, Firefox ESR < 52.9, and Firefox < 61. Puede ocurrir un desbordamiento de búfer al renderizar contenido canvas al ajustar dinámicamente la altura y anchura del elemento canvas, lo que provoca que los datos se escriban fuera de los límites calculados actualmente.

CVE-2018-0495 – ROHNP: Key Extraction Side Channel in Multiple Crypto Libraries
https://notcve.org/view.php?id=CVE-2018-0495
Libgcrypt before 1.7.10 and 1.8.x before 1.8.3 allows a memory-cache side-channel attack on ECDSA signatures that can be mitigated through the use of blinding during the signing process in the _gcry_ecc_ecdsa_sign function in cipher/ecc-ecdsa.c, aka the Return Of the Hidden Number Problem or ROHNP. To discover an ECDSA key, the attacker needs access to either the local machine or a different virtual machine on the same physical host. Libgcrypt en versiones anteriores a la 1.7.10 y versiones 1.8.x anteriores a la 1.8.3 permite un ataque de canal lateral por caché de memoria en las firmas ECDSA que se puede mitigar mediante el uso de la ocultación durante el proceso de firmado en la función _gcry_ecc_ecdsa_sign en cipher/ecc-ecdsa.c. Esto también se conoce como Return Of the Hidden Number Problem o ROHNP. Para descubrir una clave ECDSA, el atacante necesita acceso a la máquina local o a una máquina virtual diferente en el mismo host físico. • http://www.securitytracker.com/id/1041144 http://www.securitytracker.com/id/1041147 https://access.redhat.com/errata/RHSA-2018:3221 https://access.redhat.com/errata/RHSA-2018:3505 https://access.redhat.com/errata/RHSA-2019:1296 https://access.redhat.com/errata/RHSA-2019:1297 https://access.redhat.com/errata/RHSA-2019:1543 https://access.redhat.com/errata/RHSA-2019:2237 https://dev.gnupg.org/T4011 https://git.gnupg.org/cgi-bin/gitweb.cgi?p=libgcrypt.git%3Ba=commit%3 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-203: Observable Discrepancy •
CVE-2018-12020 – gnupg2: Improper sanitization of filenames allows for the display of fake status messages and the bypass of signature verification
https://notcve.org/view.php?id=CVE-2018-12020
mainproc.c in GnuPG before 2.2.8 mishandles the original filename during decryption and verification actions, which allows remote attackers to spoof the output that GnuPG sends on file descriptor 2 to other programs that use the "--status-fd 2" option. For example, the OpenPGP data might represent an original filename that contains line feed characters in conjunction with GOODSIG or VALIDSIG status codes. mainproc.c en GnuPG en versiones anteriores a la 2.2.8 gestiona de manera incorrecta el nombre de archivo original durante las acciones de descifrado y verificación, lo que permite que atacantes remotos suplanten la salida que GnuPG envía en el descriptor de archivo 2 a otros programas que emplean la opción "--status-fd 2". Por ejemplo, los datos OpenPGP podrían representar un nombre de archivo original que contiene caracteres de nueva línea junto con los códigos de estado GOODSIG o VALIDSIG. A data validation flaw was found in the way gnupg processes file names during decryption and signature validation. An attacker may be able to inject messages into gnupg verbose message logging which may have the potential to bypass the integrity of signature authentication mechanisms and could have other unintended consequences if applications take action(s) based on parsed verbose gnupg output. • http://openwall.com/lists/oss-security/2018/06/08/2 http://packetstormsecurity.com/files/152703/Johnny-You-Are-Fired.html http://seclists.org/fulldisclosure/2019/Apr/38 http://www.openwall.com/lists/oss-security/2019/04/30/4 http://www.securityfocus.com/bid/104450 http://www.securitytracker.com/id/1041051 https://access.redhat.com/errata/RHSA-2018:2180 https://access.redhat.com/errata/RHSA-2018:2181 https://dev.gnupg.org/T4012 https://github.com/RUB-NDS/Johnny • CWE-20: Improper Input Validation CWE-706: Use of Incorrectly-Resolved Name or Reference •
