Mozilla Firefox ESR < 60.5.1
Medium Nessus Plugin ID 122193
SynopsisA web browser installed on the remote macOS or Mac OS X host is affected by multiple vulnerabilities.
DescriptionThe version of Firefox ESR installed on the remote macOS or Mac OS X host is prior to 60.5.1. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2019-05 advisory.
- A use-after-free vulnerability in the Skia library can occur when creating a path, leading to a potentially exploitable crash. (CVE-2018-18356)
- An integer overflow vulnerability in the Skia library can occur after specific transform operations, leading to a potentially exploitable crash. (CVE-2019-5785)
- A buffer overflow vulnerability in the Skia library can occur with Canvas 2D acceleration on macOS. This issue was addressed by disabling Canvas 2D acceleration in Firefox ESR. *Note: this does not affect other versions and platforms where Canvas 2D acceleration is already disabled by default.* (CVE-2018-18335)
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 Firefox ESR version 60.5.1 or later.
