On Windows only, if libpcap needs to convert a Windows error message to UTF-8 and the message includes characters that UTF-8 represents using 4 bytes, utf_16le_to_utf_8_truncated() can write data beyond the end of the provided buffer.

According to the versions of the libpcap package installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

    On Windows only, if libpcap needs to convert a Windows error message to UTF-8 and the message includes     characters that UTF-8 represents using 4 bytes, utf_16le_to_utf_8_truncated() can write data beyond the     end of the provided buffer.(CVE-2025-11964)

    pcap_ether_aton() is an auxiliary function in libpcap, it takes a string argument and returns a fixed-size     allocated buffer.  The string argument must be a well-formed MAC-48 address in one of the supported     formats, but this requirement has been poorly documented.  If an application calls the function with an     argument that deviates from the expected format, the function can read data beyond the end of the provided     string and write data beyond the end of the allocated buffer.(CVE-2025-11961)

Tenable has extracted the preceding description block directly from the EulerOS Virtualization libpcap 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 Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - On Windows only, if libpcap needs to convert a Windows error message to UTF-8 and the message includes     characters that UTF-8 represents using 4 bytes, utf_16le_to_utf_8_truncated() can write data beyond the     end of the provided buffer. (CVE-2025-11964)

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

The version of libpcap installed on the remote host is prior to 1.10.6. It is, therefore, affected by multiple vulnerabilities as referenced in the SSA:2026-001-02 advisory.

    New libpcap packages are available for Slackware 15.0 and -current to fix security issues.
