The remote Fedora 37 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2023-a4e8720e0f advisory.
Offscreen Canvas did not properly track cross-origin tainting, which could have been used to access image data from another site in violation of same-origin policy. This vulnerability affects Firefox < 116, Firefox ESR < 102.14, and Firefox ESR < 115.1. (CVE-2023-4045)
In some circumstances, a stale value could have been used for a global variable in WASM JIT analysis. This resulted in incorrect compilation and a potentially exploitable crash in the content process. This vulnerability affects Firefox < 116, Firefox ESR < 102.14, and Firefox ESR < 115.1. (CVE-2023-4046)
A bug in popup notifications delay calculation could have made it possible for an attacker to trick a user into granting permissions. This vulnerability affects Firefox < 116, Firefox ESR < 102.14, and Firefox ESR < 115.1. (CVE-2023-4047)
An out-of-bounds read could have led to an exploitable crash when parsing HTML with DOMParser in low memory situations. This vulnerability affects Firefox < 116, Firefox ESR < 102.14, and Firefox ESR < 115.1. (CVE-2023-4048)
Race conditions in reference counting code were found through code inspection. These could have resulted in potentially exploitable use-after-free vulnerabilities. This vulnerability affects Firefox < 116, Firefox ESR < 102.14, and Firefox ESR < 115.1. (CVE-2023-4049)
In some cases, an untrusted input stream was copied to a stack buffer without checking its size. This resulted in a potentially exploitable crash which could have led to a sandbox escape. This vulnerability affects Firefox < 116, Firefox ESR < 102.14, and Firefox ESR < 115.1. (CVE-2023-4050)
A website could have obscured the full screen notification by using the file open dialog. This could have led to user confusion and possible spoofing attacks. This vulnerability affects Firefox < 116, Firefox ESR < 115.2, and Thunderbird < 115.2. (CVE-2023-4051)
The Firefox updater created a directory writable by non-privileged users. When uninstalling Firefox, any files in that directory would be recursively deleted with the permissions of the uninstalling user account. This could be combined with creation of a junction (a form of symbolic link) to allow arbitrary file deletion controlled by the non-privileged user. This bug only affects Firefox on Windows. Other operating systems are unaffected. This vulnerability affects Firefox < 116, Firefox ESR < 115.1, and Thunderbird < 115.1. (CVE-2023-4052)
A website could have obscured the full screen notification by using a URL with a scheme handled by an external program, such as a mailto URL. This could have led to user confusion and possible spoofing attacks. This vulnerability affects Firefox < 116, Firefox ESR < 115.2, and Thunderbird < 115.2.
(CVE-2023-4053)
When opening appref-ms files, Firefox did not warn the user that these files may contain malicious code.
This bug only affects Firefox on Windows. Other operating systems are unaffected. This vulnerability affects Firefox < 116, Firefox ESR < 102.14, Firefox ESR < 115.1, Thunderbird < 102.14, and Thunderbird < 115.1. (CVE-2023-4054)
When the number of cookies per domain was exceeded in document.cookie
, the actual cookie jar sent to the host was no longer consistent with expected cookie jar state. This could have caused requests to be sent with some cookies missing. This vulnerability affects Firefox < 116, Firefox ESR < 102.14, and Firefox ESR < 115.1. (CVE-2023-4055)
Memory safety bugs present in Firefox 115, Firefox ESR 115.0, Firefox ESR 102.13, Thunderbird 115.0, and Thunderbird 102.13. Some of these bugs showed evidence of memory corruption and we presume that with enough effort some of these could have been exploited to run arbitrary code. This vulnerability affects Firefox < 116, Firefox ESR < 102.14, and Firefox ESR < 115.1. (CVE-2023-4056)
Memory safety bugs present in Firefox 115, Firefox ESR 115.0, and Thunderbird 115.0. Some of these bugs showed evidence of memory corruption and we presume that with enough effort some of these could have been exploited to run arbitrary code. This vulnerability affects Firefox < 116, Firefox ESR < 115.1, and Thunderbird < 115.1. (CVE-2023-4057)
Memory safety bugs present in Firefox 115. Some of these bugs showed evidence of memory corruption and we presume that with enough effort some of these could have been exploited to run arbitrary code. This vulnerability affects Firefox < 116. (CVE-2023-4058)
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
