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
