CVE-2018-12389

Mozilla developers and community members reported memory safety bugs present in Firefox ESR 60.2. Some of these bugs showed evidence of memory corruption and we presume that with enough effort that some of these could be exploited to run arbitrary code. This vulnerability affects Firefox ESR < 60.3 and Thunderbird < 60.3.

This update for Mozilla Thunderbird to version 60.2.1 fixes multiple issues.

Multiple security issues were fixed in the Mozilla platform as advised in MFSA 2018-25 and MFSA 2018-28. In general, these flaws cannot be exploited through email in Thunderbird because scripting is disabled when reading mail, but are potentially risks in browser or browser-like contexts:
