Mozilla Thunderbird < 68.2
Medium Nessus Plugin ID 130364
SynopsisA mail client installed on the remote macOS or Mac OS X host is affected by multiple vulnerabilities.
DescriptionThe 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.
Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
SolutionUpgrade to Mozilla Thunderbird version 68.2 or later.
