The version of mozilla-firefox installed on the remote host is prior to 115.3.0esr. It is, therefore, affected by multiple vulnerabilities as referenced in the SSA:2023-269-01 advisory.
A compromised content process could have provided malicious data to <code>FilterNodeD2D1</code> resulting in an out-of-bounds write, leading to a potentially exploitable crash in a privileged process.
(CVE-2023-5168)
A compromised content process could have provided malicious data in a <code>PathRecording</code> resulting in an out-of-bounds write, leading to a potentially exploitable crash in a privileged process.
(CVE-2023-5169)
During Ion compilation, a Garbage Collection could have resulted in a use-after-free condition, allowing an attacker to write two NUL bytes, and cause a potentially exploitable crash. (CVE-2023-5171)
If Windows failed to duplicate a handle during process creation, the sandbox code may have inadvertently freed a pointer twice, resulting in a use-after-free and a potentially exploitable crash. This bug only affects Firefox on Windows when run in non-standard configurations (such as using <code>runas</code>).
Other operating systems are unaffected. (CVE-2023-5174)
Memory safety bugs present in Firefox 117, Firefox ESR 115.2, and Thunderbird 115.2. 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. (CVE-2023-5176)
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
