https://notcve.org/view.php?id=CVE-2017-5428
An integer overflow in "createImageBitmap()" was reported through the Pwn2Own contest. The fix for this vulnerability disables the experimental extensions to the "createImageBitmap" API. This function runs in the content sandbox, requiring a second vulnerability to compromise a user's computer. This vulnerability affects Firefox ESR < 52.0.1 and Firefox < 52.0.1.

CVSS: 7.5EPSS: 0%CPEs: 6EXPL: 1CVE-2016-10196 – libevent: Stack-buffer overflow in evutil_parse_sockaddr_port()
https://notcve.org/view.php?id=CVE-2016-10196
Stack-based buffer overflow in the evutil_parse_sockaddr_port function in evutil.c in libevent before 2.1.6-beta allows attackers to cause a denial of service (segmentation fault) via vectors involving a long string in brackets in the ip_as_string argument. Desbordamiento de búfer en la función evutil_parse_sockaddr_port en evutil.c en libevent en versiones anteriores a 2.1.6-beta permite a atacantes provocar una denegación de servicio (fallo de segmentación) a través de vectores que implican una cadena larga entre corchetes en el argumento ip_as_string. A vulnerability was found in libevent with the parsing of IPv6 addresses. If an attacker could cause an application using libevent to parse a malformed address in IPv6 notation of more than 2GiB in length, a stack overflow would occur leading to a crash. • http://www.debian.org/security/2017/dsa-3789 http://www.openwall.com/lists/oss-security/2017/01/31/17 http://www.openwall.com/lists/oss-security/2017/02/02/7 http://www.securityfocus.com/bid/96014 http://www.securitytracker.com/id/1038320 https://access.redhat.com/errata/RHSA-2017:1104 https://access.redhat.com/errata/RHSA-2017:1106 https://access.redhat.com/errata/RHSA-2017:1201 https://bugzilla.mozilla.org/show_bug.cgi?id=1343453 https://github.com/libeve • CWE-121: Stack-based Buffer Overflow CWE-787: Out-of-bounds Write •

https://notcve.org/view.php?id=CVE-2017-5402
A use-after-free can occur when events are fired for a "FontFace" object after the object has been already been destroyed while working with fonts. This results in a potentially exploitable crash. This vulnerability affects Firefox < 52, Firefox ESR < 45.8, Thunderbird < 52, and Thunderbird < 45.8.

CVSS: 6.5EPSS: 0%CPEs: 22EXPL: 1CVE-2017-5407 – Mozilla: Pixel and history stealing via floating-point timing side channel with SVG filters (MFSA 2017-06)
https://notcve.org/view.php?id=CVE-2017-5407
Using SVG filters that don't use the fixed point math implementation on a target iframe, a malicious page can extract pixel values from a targeted user. This can be used to extract history information and read text values across domains. This violates same-origin policy and leads to information disclosure. This vulnerability affects Firefox < 52, Firefox ESR < 45.8, Thunderbird < 52, and Thunderbird < 45.8. Mediante el uso de filtros SVG que no emplean la implementación de matemática de punto fijo en un iframe objetivo, una página maliciosa puede extraer valores de píxeles de un usuario objetivo. • http://rhn.redhat.com/errata/RHSA-2017-0459.html http://rhn.redhat.com/errata/RHSA-2017-0461.html http://rhn.redhat.com/errata/RHSA-2017-0498.html http://www.securityfocus.com/bid/96693 http://www.securitytracker.com/id/1037966 https://bugzilla.mozilla.org/show_bug.cgi?id=1336622 https://security.gentoo.org/glsa/201705-06 https://security.gentoo.org/glsa/201705-07 https://www.debian.org/security/2017/dsa-3805 https://www.debian.org/security/2017/dsa-3832 https • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
