NewStart CGSL MAIN 5.04 : firefox Multiple Vulnerabilities (NS-SA-2019-0001)
Critical Nessus Plugin ID 127141
SynopsisThe remote machine is affected by multiple vulnerabilities.
DescriptionThe remote NewStart CGSL host, running version MAIN 5.04, has firefox packages installed that are affected by multiple vulnerabilities:
- A privacy flaw was discovered in Firefox. In Private Browsing mode, a web worker could write persistent data to IndexedDB, which was not cleared when exiting and would persist across multiple sessions. A malicious website could exploit the flaw to bypass private- browsing protections and uniquely fingerprint visitors.
- A use-after-free vulnerability can occur when flushing and resizing layout because the PressShell object has been freed while still in use. This results in a potentially exploitable crash during these operations.
This vulnerability affects Firefox < 57, Firefox ESR < 52.5, and Thunderbird < 52.5. (CVE-2017-7828)
- Memory safety bugs were reported in Firefox 56 and Firefox ESR 52.4. 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. This vulnerability affects Firefox < 57, Firefox ESR < 52.5, and Thunderbird < 52.5. (CVE-2017-7826)
- The Resource Timing API incorrectly revealed navigations in cross-origin iframes. This is a same-origin policy violation and could allow for data theft of URLs loaded by users. This vulnerability affects Firefox < 57, Firefox ESR < 52.5, and Thunderbird < 52.5.
Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
