    A vulnerability has been identified in the libarchive library. This flaw can be triggered when file     streams are piped into bsdtar, potentially allowing for reading past the end of the file. This out-of-     bounds read can lead to unintended consequences, including unpredictable program behavior, memory     corruption, or a denial-of-service condition.(CVE-2025-5918)

    A vulnerability has been identified in the libarchive library. This flaw involves an 'off-by-one'     miscalculation when handling prefixes and suffixes for file names. This can lead to a 1-byte write     overflow. While seemingly small, such an overflow can corrupt adjacent memory, leading to unpredictable     program behavior, crashes, or in specific circumstances, could be leveraged as a building block for more     sophisticated exploitation.(CVE-2025-5917)

    A vulnerability has been identified in the libarchive library. This flaw involves an integer overflow that     can be triggered when processing a Web Archive (WARC) file that claims to have more than INT64_MAX - 4     content bytes. An attacker could craft a malicious WARC archive to induce this overflow, potentially     leading to unpredictable program behavior, memory corruption, or a denial-of-service condition within     applications that process such archives using libarchive.(CVE-2025-5916)

    A vulnerability has been identified in the libarchive library, specifically within the     archive_read_format_rar_seek_data() function. This flaw involves an integer overflow that can ultimately     lead to a double-free condition. Exploiting a double-free vulnerability can result in memory corruption,     enabling an attacker to execute arbitrary code or cause a denial-of-service condition.(CVE-2025-5914)

The remote host is running a version of macOS / Mac OS X that is 26.x prior to 26.2. It is, therefore, affected by multiple vulnerabilities:

  - A vulnerability has been identified in the libarchive library. This flaw can be triggered when file     streams are piped into bsdtar, potentially allowing for reading past the end of the file. This out-of-     bounds read can lead to unintended consequences, including unpredictable program behavior, memory     corruption, or a denial-of-service condition. (CVE-2025-5918)

  - libcurl's ASN1 parser code has the `GTime2str()` function, used for parsing an ASN.1 Generalized Time     field. If given an syntactically incorrect field, the parser might end up using -1 for the length of the
    *time fraction*, leading to a `strlen()` getting performed on a pointer to a heap buffer area that is not     (purposely) null terminated. This flaw most likely leads to a crash, but can also lead to heap contents     getting returned to the application when     [CURLINFO_CERTINFO](https://curl.se/libcurl/c/CURLINFO_CERTINFO.html) is used. (CVE-2024-7264)

The version of Tencent Linux installed on the remote TencentOS Server 4 host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the TSSA-2025:0465 advisory.

    Package updates are available for TencentOS Server 4 that fix the following vulnerabilities:

    CVE-2025-5918:
    A vulnerability has been identified in the libarchive library. This flaw can be triggered when file     streams are piped into bsdtar, potentially allowing for reading past the end of the file. This out-of-     bounds read can lead to unintended consequences, including unpredictable program behavior, memory     corruption, or a denial-of-service condition.

    CVE-2025-5917:
    A vulnerability has been identified in the libarchive library. This flaw involves an 'off-by-one'     miscalculation when handling prefixes and suffixes for file names. This can lead to a 1-byte write     overflow. While seemingly small, such an overflow can corrupt adjacent memory, leading to unpredictable     program behavior, crashes, or in specific circumstances, could be leveraged as a building block for more     sophisticated exploitation.

    CVE-2025-5916:
    A vulnerability has been identified in the libarchive library. This flaw involves an integer overflow that     can be triggered when processing a Web Archive (WARC) file that claims to have more than INT64_MAX - 4     content bytes. An attacker could craft a malicious WARC archive to induce this overflow, potentially     leading to unpredictable program behavior, memory corruption, or a denial-of-service condition within     applications that process such archives using libarchive.

    CVE-2025-5915:
    A vulnerability has been identified in the libarchive library. This flaw can lead to a heap buffer over-     read due to the size of a filter block potentially exceeding the Lempel-Ziv-Storer-Schieber (LZSS) window.
    This means the library may attempt to read beyond the allocated memory buffer, which can result in     unpredictable program behavior, crashes (denial of service), or the disclosure of sensitive information     from adjacent memory regions.

    CVE-2025-5914:
    A vulnerability has been identified in the libarchive library, specifically within the     archive_read_format_rar_seek_data() function. This flaw involves an integer overflow that can ultimately     lead to a double-free condition. Exploiting a double-free vulnerability can result in memory corruption,     enabling an attacker to execute arbitrary code or cause a denial-of-service condition.
