USN-3477-1 fixed vulnerabilities in Firefox. The update introduced various
minor regressions. This update fixes the problems.
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 cause a denial of service, read uninitialized
memory, obtain sensitive information, bypass same-origin restrictions,
bypass CSP protections, bypass mixed content blocking, spoof the
addressbar, or execute arbitrary code. (CVE-2017-7826, CVE-2017-7827,
CVE-2017-7828, CVE-2017-7830, CVE-2017-7831, CVE-2017-7832, CVE-2017-7833,
CVE-2017-7834, CVE-2017-7835, CVE-2017-7837, CVE-2017-7838, CVE-2017-7842)
It was discovered that javascript: URLs pasted in to the addressbar
would be executed instead of being blocked in some circumstances. If a
user were tricked in to copying a specially crafted URL in to the
addressbar, an attacker could potentially exploit this to conduct
cross-site scripting (XSS) attacks. (CVE-2017-7839)
It was discovered that exported bookmarks do not strip script elements
from user-supplied tags. If a user were tricked in to adding specially
crafted tags to bookmarks, exporting them and then opening the resulting
HTML file, an attacker could potentially exploit this to conduct
cross-site scripting (XSS) attacks. (CVE-2017-7840)
