Incorrect garbage collection interaction could have led to a use-after-free. This vulnerability affects Firefox < 129.

The remote Ubuntu 20.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-6966-1 advisory.

    Multiple security issues were discovered in Firefox. If a user were tricked into opening a specially     crafted website, an attacker could potentially exploit these to cause a denial of service, obtain     sensitive information across domains, or execute arbitrary code. (CVE-2024-7518, CVE-2024-7521,     CVE-2024-7524, CVE-2024-7526, CVE-2024-7527, CVE-2024-7528, CVE-2024-7529, CVE-2024-7530, CVE-2024-7531)

    It was discovered that Firefox did not properly manage certain memory operations when processing graphics     shared memory. An attacker could potentially exploit this issue to escape the sandbox. (CVE-2024-7519)

    Nan Wang discovered that Firefox did not properly handle type check in WebAssembly. An attacker could     potentially exploit this issue to execute arbitrary code. (CVE-2024-7520)

    Irvan Kurniawan discovered that Firefox did not properly check an attribute value in the editor component,     leading to an out-of-bounds read vulnerability. An attacker could possibly use this issue to cause a     denial of service or expose sensitive information. (CVE-2024-7522)

    Rob Wu discovered that Firefox did not properly check permissions when creating a StreamFilter. An     attacker could possibly use this issue to modify response body of requests on any site using a web     extension. (CVE-2024-7525)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

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

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the 5d7939f6-5989-11ef-9793-b42e991fc52e advisory.

The remote Fedora 40 host has packages installed that are affected by multiple vulnerabilities as referenced in the FEDORA-2024-7f0a88301b advisory.

    Update NSS to 3.103.0     Update to Firefox 129.0

The version of Firefox installed on the remote macOS or Mac OS X host is prior to 129.0. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2024-33 advisory.

  - Select options could obscure the fullscreen notification dialog. This could be used by a malicious site to     perform a spoofing attack. (CVE-2024-7518)

  - Insufficient checks when processing graphics shared memory could have led to memory corruption. This could     be leveraged by an attacker to perform a sandbox escape. (CVE-2024-7519)

  - A type confusion bug in WebAssembly could be leveraged by an attacker to potentially achieve code     execution. (CVE-2024-7520)

  - Incomplete WebAssembly exception handing could have led to a use-after-free. (CVE-2024-7521)

  - Editor code failed to check an attribute value. This could have led to an out-of-bounds read.
    (CVE-2024-7522)

  - A select option could partially obscure security prompts. This could be used by a malicious site to trick     a user into granting permissions.  This issue only affects Android versions of Firefox. (CVE-2024-7523)

  - Firefox adds web-compatibility shims in place of some tracking scripts blocked by Enhanced Tracking     Protection.  On a site protected by Content Security Policy in strict-dynamic mode, an attacker able to     inject an HTML element could have used a DOM Clobbering attack on some of the shims and achieved XSS,     bypassing the CSP strict-dynamic protection. (CVE-2024-7524)

  - It was possible for a web extension with minimal permissions to create a <code>StreamFilter</code> which     could be used to read and modify the response body of requests on any site. (CVE-2024-7525)

  - ANGLE failed to initialize parameters which lead to reading from uninitialized memory. This could be     leveraged to leak sensitive data from memory. (CVE-2024-7526)

  - Unexpected marking work at the start of sweeping could have led to a use-after-free. (CVE-2024-7527)

  - Incorrect garbage collection interaction in IndexedDB could have led to a use-after-free. (CVE-2024-7528)

  - The date picker could partially obscure security prompts. This could be used by a malicious site to trick     a user into granting permissions. (CVE-2024-7529)

  - Incorrect garbage collection interaction could have led to a use-after-free. (CVE-2024-7530)

  - Calling <code>PK11Encrypt()</code> in NSS using CKMCHACHA20 and the same buffer for input and output can     result in plaintext on an Intel Sandy Bridge processor. In Firefox this only affects the QUIC header     protection feature when the connection is using the ChaCha20-Poly1305 cipher suite. The most likely     outcome is connection failure, but if the connection persists despite the high packet loss it could be     possible for a network observer to identify packets as coming from the same source despite a network path     change. (CVE-2024-7531)
