New! Vulnerability Priority Rating (VPR)
Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.

Synopsis
A mail client installed on the remote macOS or Mac OS X host is affected by multiple vulnerabilities.
Description
The version of Thunderbird installed on the remote macOS or Mac OS X host is prior to 68.2. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2019-35 advisory.
- In libexpat before 2.2.8, crafted XML input could fool the parser into changing from DTD parsing to document parsing too early; a consecutive call to XML_GetCurrentLineNumber (or XML_GetCurrentColumnNumber) then resulted in a heap-based buffer over-read.
(CVE-2019-15903)
Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
Solution
Upgrade to Mozilla Thunderbird version 68.2 or later.
