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 60.6.1. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2019-12 advisory.
- Incorrect alias information in IonMonkey JIT compiler for Array.prototype.slice method may lead to missing bounds check and a buffer overflow. (CVE-2019-9810)
- Incorrect handling of __proto__ mutations may lead to type confusion in IonMonkey JIT code and can be leveraged for arbitrary memory read and write.
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 60.6.1 or later.
