The updated packages fix several bugs and some security issues:

Buffer overflow using computed size of canvas element. (CVE-2018-12359)

Use-after-free when using focus(). (CVE-2018-12360)

S/MIME and PGP decryption oracles can be built with HTML emails.

S/MIME plaintext can be leaked through HTML reply/forward. (CVE-2018-12373)

Integer overflow in SSSE3 scaler. (CVE-2018-12362)

Use-after-free when appending DOM nodes. (CVE-2018-12363)

CSRF attacks through 307 redirects and NPAPI plugins. (CVE-2018-12364)

Compromised IPC child process can list local filenames. (CVE-2018-12365)

Invalid data handling during QCMS transformations. (CVE-2018-12366)

Using form to exfiltrate encrypted mail part by pressing enter in form field.

Memory safety bugs fixed in Firefox 60, Firefox ESR 60.1, Firefox ESR 52.9,
and Thunderbird 52.9. (CVE-2018-5188)

The signature verification routine in Enigmail before 2.0.7 interprets user
ids as status/control messages and does not correctly keep track of the
status of multiple signatures, which allows remote attackers to spoof
arbitrary email signatures via public keys containing crafted primary user
ids. (CVE-2018-12019)

mainproc.c in GnuPG before 2.2.8 mishandles the original filename during
decryption and verification actions, which allows remote attackers to spoof
the output that GnuPG sends on file descriptor 2 to other programs that use
the "--status-fd 2" option. For example, the OpenPGP data might represent an
original filename that contains line feed characters in conjunction with
GOODSIG or VALIDSIG status codes. (CVE-2018-12020)
