Description

Mozilla Thunderbird is a standalone mail and newsgroup client.

This update upgrades Thunderbird to version 60.2.1.

Security Fix(es):

• Mozilla: Memory safety bugs fixed in Firefox 62 and Firefox ESR 60.2 (CVE-2018-12376)
  
• Mozilla: Use-after-free in driver timers (CVE-2018-12377)
  
• Mozilla: Use-after-free in IndexedDB (CVE-2018-12378)
  
• Mozilla: Proxy bypass using automount and autofs (CVE-2017-16541)
  
• Mozilla: Out-of-bounds write with malicious MAR file (CVE-2018-12379)

• Mozilla: Setting a master password post-Firefox 58 does not delete unencrypted previously stored passwords (CVE-2018-12383)
  

Note: All of the above issues cannot be exploited in Thunderbird by a specially crafted HTML mail, as JavaScript is disabled for mail messages and cannot be enabled. They could be exploited another way in Thunderbird, for example, when viewing the remote content of an RSS feed.
