Title: Firefox vulnerabilities
Summary: Firefox could be made to crash or run programs as your login if it
opened a malicious website.
Multiple security issues were discovered in Firefox. If a user were
tricked into opening a specially crafted website, an attacker could
potentially exploit these to cause a denial of service, obtain sensitive
information, trick a user into accepting unwanted permissions, or execute
arbitrary code.
Instructions: After a standard system update you need to restart Firefox to make
all the necessary changes.
