CVE-2017-5430 – Mozilla: Memory safety bugs fixed in Firefox 53 and Firefox ESR 52.1 (MFSA 2017-12)
https://notcve.org/view.php?id=CVE-2017-5430
Memory safety bugs were reported in Firefox 52, Firefox ESR 52, and Thunderbird 52. 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 Thunderbird < 52.1, Firefox ESR < 52.1, and Firefox < 53. Se han reportado errores de seguridad de memoria en Firefox 52, Firefox ESR 52, y Thunderbird 52. Algunos de estos errores mostraron evidencias de corrupción de memoria y se entiende que, con el suficiente esfuerzo, algunos de estos podrían explotarse para ejecutar código arbitrario. • http://www.securityfocus.com/bid/97940 http://www.securitytracker.com/id/1038320 https://access.redhat.com/errata/RHSA-2017:1106 https://bugzilla.mozilla.org/buglist.cgi?bug_id=1342101%2C1340482%2C1344686%2C1329796%2C1346419%2C1349621%2C1344081%2C1344305%2C1348143%2C1349719%2C1353476%2C1337418%2C1346140%2C1339722 https://www.mozilla.org/security/advisories/mfsa2017-10 https://www.mozilla.org/security/advisories/mfsa2017-12 https://www.mozilla.org/security/advisories/mfsa2017-13 https://access.redhat.com/security/ • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
