An update of the mozjs package has been released.

The version of firefox installed on the remote host is prior to 102.7.0-1. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2FIREFOX-2023-013 advisory.

    Mozilla developers and community members Julian Hector, Randell Jesup, Gabriele Svelto, Tyson Smith,     Christian Holler, and Masayuki Nakano reported memory safety bugs present in Firefox 94. 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 < 95, Firefox ESR < 91.4.0, and     Thunderbird < 91.4.0. (CVE-2021-4129)

    A flaw was found in Mozilla. The Mozilla Foundation Security Advisory describes the issue of if an     attacker corrupted an object prototype, they could set undesired attributes on a JavaScript object,     leading to privileged code execution. (CVE-2022-2200)

    An out-of-bounds read can occur when decoding H264 video. This results in a potentially exploitable crash.
    This vulnerability affects Firefox ESR < 102.3, Thunderbird < 102.3, and Firefox < 105. (CVE-2022-3266)

    A flaw was found in Mozilla. The Mozilla Foundation Security Advisory describes the issue of an iframe     that was not permitted to run scripts could do so if the user clicked on a `javascript:` link.
    (CVE-2022-34468)

    A flaw was found in Mozilla. The Mozilla Foundation Security Advisory describes the issue of navigations     between XML documents that may have led to a use-after-free problem and a potentially exploitable crash.
    (CVE-2022-34470)

    A flaw was found in Mozilla. The Mozilla Foundation Security Advisory describes the issue that if a PAC     URL was set and the server that hosts the PAC was not reachable, OCSP requests are blocked, resulting in     incorrect error pages being shown. (CVE-2022-34472)

    A flaw was found in Mozilla. The Mozilla Foundation Security Advisory describes the issue of a malicious     website that creates a popup that could have resized the popup to overlay the address bar with its own     content, resulting in potential user confusion or spoofing attacks. (CVE-2022-34479)

    A flaw was found in Mozilla. The Mozilla Foundation Security Advisory describes the issue within the     `nsTArray_Impl::ReplaceElementsAt()` function, where an integer overflow could occur when the number of     elements to replace was too large for the container. (CVE-2022-34481)

    A flaw was found in Mozilla. The Mozilla Foundation Security Advisory describes the issue of the Mozilla     Fuzzing Team reporting potential vulnerabilities present in Firefox 101 and Firefox ESR 91.10. 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-2022-34484)

    RESERVEDNOTE: https://www.mozilla.org/en-US/security/advisories/mfsa2022-51/#CVE-2022-46871     (CVE-2022-46871)

    By confusing the browser, the fullscreen notification could have been delayed or suppressed, resulting in     potential user confusion or spoofing attacks. This vulnerability affects Firefox < 108. (CVE-2022-46877)

    The Mozilla Foundation Security Advisory describes this flaw as:

    Due to the Firefox GTK wrapper code's use of text/plain for drag data and GTK treating all text/plain     MIMEs containing file URLs as being dragged a website could arbitrarily read a file via a call to     DataTransfer.setData. (CVE-2023-23598)

    The Mozilla Foundation Security Advisory describes this flaw as:

    When copying a network request from the developer tools panel as a curl command the output was not being     properly sanitized and could allow arbitrary commands to be hidden within. (CVE-2023-23599)

    The Mozilla Foundation Security Advisory describes this flaw as:

    Navigations were being allowed when dragging a URL from a cross-origin iframe into the same tab which     could lead to website spoofing attacks (CVE-2023-23601)

    The Mozilla Foundation Security Advisory describes this flaw as:

    A mishandled security check when creating a WebSocket in a WebWorker caused the Content Security Policy     connect-src header to be ignored. This could lead to connections to restricted origins from inside     WebWorkers. (CVE-2023-23602)

    Regular expressions used to filter out forbidden properties and values from style directives in calls to     console.log weren't accounting for external URLs. Data could then be potentially exfiltrated from the     browser. (CVE-2023-23603)

    The Mozilla Foundation Security Advisory describes this flaw as:

    Mozilla developers and the Mozilla Fuzzing Team reported memory safety bugs present in Firefox 108 and     Firefox ESR 102.6. 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-2023-23605)

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

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