Details

Robert Kaiser discovered a use-after-free during plugin initialization in
some circumstances. If a user were tricked in to opening a specially
crafted website, an attacker could potentially exploit this to cause a
denial of service via application crash or execute arbitrary code with the
privileges of the user invoking Firefox. (CVE-2015-2706)

The problem can be corrected by updating your system to the following package versions:

After a standard system update you need to restart Firefox to make
all the necessary changes.
