Slackware Linux 15.0 / current mozilla-firefox Multiple Vulnerabilities (SSA:2023-297-01)

critical Nessus Plugin ID 183835


The remote Slackware Linux host is missing a security update to mozilla-firefox.


The version of mozilla-firefox installed on the remote host is prior to 115.4.0esr. It is, therefore, affected by multiple vulnerabilities as referenced in the SSA:2023-297-01 advisory.

- It was possible for certain browser prompts and dialogs to be activated or dismissed unintentionally by the user due to an insufficient activation-delay. (CVE-2023-5721)

- Drivers are not always robust to extremely large draw calls and in some cases this scenario could have led to a crash. (CVE-2023-5724)

- A malicious installed WebExtension could open arbitrary URLs, which under the right circumstance could be leveraged to collect sensitive user data. (CVE-2023-5725)

- 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. Note: This issue only affected macOS operating systems. Other operating systems are unaffected. (CVE-2023-5726)

- The executable file warning was not presented when downloading .msix, .msixbundle, .appx, and .appxbundle files, which can run commands on a user's computer. Note: This issue only affected Windows operating systems. Other operating systems are unaffected. (CVE-2023-5727)

- During garbage collection extra operations were performed on a object that should not be. This could have led to a potentially exploitable crash. (CVE-2023-5728)

- Memory safety bugs present in Firefox 118, Firefox ESR 115.3, and Thunderbird 115.3. 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-2023-5730)

- An attacker could have created a malicious link using bidirectional characters to spoof the location in the address bar when visited. (CVE-2023-5732)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.


Upgrade the affected mozilla-firefox package.
