Mozilla Firefox ESR 45.x < 45.7 Multiple Vulnerabilities (macOS)
High Nessus Plugin ID 96773
SynopsisThe remote macOS or Mac OS X host contains a web browser that is affected by multiple vulnerabilities.
DescriptionThe version of Mozilla Firefox ESR installed on the remote macOS or Mac OS X host is 45.x prior to 45.7. It is, therefore, affected by the following vulnerabilities :
- Mozilla developers and community members Christian Holler, Gary Kwong, Andre Bargull, Jan de Mooij, Tom Schuster, and Oriol reported memory safety bugs present in Firefox 50.1 and Firefox ESR 45.6. Some of these bugs showed evidence of memory corruption and we presume that with enough effort that some of these could be exploited to run arbitrary code.
- JIT code allocation can allow for a bypass of ASLR and DEP protections leading to potential memory corruption attacks. (CVE-2017-5375)
- Use-after-free while manipulating XSL in XSLT documents (CVE-2017-5376)
- A potential use-after-free found through fuzzing during DOM manipulation of SVG content. (CVE-2017-5380)
- URLs containing certain unicode glyphs for alternative hyphens and quotes do not properly trigger punycode display, allowing for domain name spoofing attacks in the location bar. (CVE-2017-5383)
- WebExtension scripts can use the 'data:' protocol to affect pages loaded by other web extensions using this protocol, leading to potential data disclosure or privilege escalation in affected extensions.
- The JSON viewer in the Developer Tools uses insecure methods to create a communication channel for copying and viewing JSON or HTTP headers data, allowing for potential privilege escalation. (CVE-2017-5390)
- A use-after-free vulnerability in the Media Decoder when working with media files when some events are fired after the media elements are freed from memory.
