USN-3435-1 fixed vulnerabilities in Firefox. The update caused the Flash
plugin to crash in some circumstances. This update fixes the problem.
We apologize for the inconvenience.
Original advisory details:
Multiple security issues were discovered in Firefox. If a user were
tricked in to opening a specially crafted website, an attacker could
potentially exploit these to read uninitialized memory, obtain sensitive
information, bypass phishing and malware protection, spoof the origin in
modal dialogs, conduct cross-site scripting (XSS) attacks, cause a denial
of service via application crash, or execute arbitrary code.
(CVE-2017-7793, CVE-2017-7810, CVE-2017-7811, CVE-2017-7812,
CVE-2017-7813, CVE-2017-7814, CVE-2017-7815, CVE-2017-7818, CVE-2017-7819,
CVE-2017-7820, CVE-2017-7822, CVE-2017-7823, CVE-2017-7824)
Martin Thomson discovered that NSS incorrectly generated handshake hashes.
A remote attacker could potentially exploit this to cause a denial of
service via application crash, or execute arbitrary code. (CVE-2017-7805)
Multiple security issues were discovered in WebExtensions. If a user were
tricked in to installing a specially crafted extension, an attacker could
potentially exploit these to download and open non-executable files
without interaction, or obtain elevated privileges. (CVE-2017-7816,
CVE-2017-7821)
