7-Zip Zstandard Decompression Integer Underflow Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of 7-Zip. Interaction with this library is required to exploit this vulnerability but attack vectors may vary depending on the implementation. The specific flaw exists within the implementation of Zstandard decompression. The issue results from the lack of proper validation of user-supplied data, which can result in an integer underflow before writing to memory. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-24346.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - 7-Zip Zstandard Decompression Integer Underflow Remote Code Execution Vulnerability. This vulnerability     allows remote attackers to execute arbitrary code on affected installations of 7-Zip. Interaction with     this library is required to exploit this vulnerability but attack vectors may vary depending on the     implementation. The specific flaw exists within the implementation of Zstandard decompression. The issue     results from the lack of proper validation of user-supplied data, which can result in an integer underflow     before writing to memory. An attacker can leverage this vulnerability to execute code in the context of     the current process. Was ZDI-CAN-24346. (CVE-2024-11477)

Note that Nessus relies on the presence of the package as reported by the vendor.

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

  - An out-of-bounds write issue was addressed with improved checks to prevent unauthorized actions. This
    issue is fixed in Safari 18.3.1, iOS 15.8.4 and iPadOS 15.8.4, iOS 16.7.11 and iPadOS 16.7.11, iOS 18.3.2
    and iPadOS 18.3.2, iPadOS 17.7.6, macOS Sequoia 15.3.2, visionOS 2.3.2, watchOS 11.4. Maliciously crafted
    web content may be able to break out of Web Content sandbox. This is a supplementary fix for an attack
    that was blocked in iOS 17.2. (Apple is aware of a report that this issue may have been exploited in an
    extremely sophisticated attack against specific targeted individuals on versions of iOS before iOS 17.2.).

  - Out of bounds memory access in V8 in Google Chrome prior to 131.0.6778.204 allowed a remote attacker to
    execute arbitrary code inside a sandbox via a crafted HTML page. (Chromium security severity: High)
    (CVE-2024-12693)

  - Use after free in Compositing in Google Chrome prior to 131.0.6778.204 allowed a remote attacker to
    potentially exploit heap corruption via a crafted HTML page. (Chromium security severity: High)
    (CVE-2024-12694)

  - xsltGetInheritedNsList in libxslt before 1.1.43 has a use-after-free issue related to exclusion of result
    prefixes. (CVE-2024-55549)

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 7cb6642c-0c5a-11f0-8688-4ccc6adda413 advisory.

    Qt qtwebengine-chromium repo reports:
    Backports for 11 security bugs in Chromium:

Tenable has extracted the preceding description block directly from the FreeBSD 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 7-Zip installed on the remote host is prior to 24.07. It is, therefore, affected by a remote code execution vulnerability as referenced in the ZDI-24-1532 advisory.
