The remote Ubuntu 20.04 LTS / 22.04 LTS / 24.04 LTS / 24.10 / 25.04 host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-7454-1 advisory.

    It was discovered that the libarchive bsdunzip utility incorrectly handled certain ZIP archive files. If a     user or automated system were tricked into processing a specially crafted ZIP archive, an attacker could     use this issue to cause libarchive to crash, resulting in a denial of service, or possibly execute     arbitrary code. This issue only affected Ubuntu 24.04 LTS, Ubuntu 24.10, and Ubuntu 25.04. (CVE-2025-1632)

    It was discovered that libarchive incorrectly handled certain TAR archive files. If a user or automated     system were tricked into processing a specially crafted TAR archive, an attacker could use this issue to     cause libarchive to crash, resulting in a denial of service, or possibly execute arbitrary code.

The version of libarchive installed on the remote Azure Linux 3.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2025-1632 advisory.

  - A vulnerability was found in libarchive up to 3.7.7. It has been classified as problematic. This affects     the function list of the file bsdunzip.c. The manipulation leads to null pointer dereference. It is     possible to launch the attack on the local host. The exploit has been disclosed to the public and May be     used. The vendor was contacted early about this disclosure but did not respond in any way. (CVE-2025-1632)

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-2025:0223 advisory.

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

    CVE-2025-25724:
    list_item_verbose in tar/util.c in libarchive through 3.7.7 does not check an strftime return value, which     can lead to a denial of service or unspecified other impact via a crafted TAR archive that is read with a     verbose value of 2. For example, the 100-byte buffer may not be sufficient for a custom locale.

The remote NewStart CGSL host, running version MAIN 7.02, has libarchive packages installed that are affected by multiple vulnerabilities:

  - list_item_verbose in tar/util.c in libarchive through 3.7.7 does not check an strftime return value, which     can lead to a denial of service or unspecified other impact via a crafted TAR archive that is read with a     verbose value of 2.

  - Libarchive through 3.6.2 can cause directories to have world-writable permissions. The umask() call inside     archive_write_disk_posix.c changes the umask of the whole process for a very short period of time; a race     condition with another thread can lead to a permanent umask 0 setting. Such a race condition could lead to     implicit directory creation with permissions 0777 (without the sticky bit), which means that any low-     privileged local user can delete and rename files inside those directories. (CVE-2023-30571)

  - Libarchive Remote Code Execution Vulnerability (CVE-2024-26256)

  - execute_filter_audio in archive_read_support_format_rar.c in libarchive before 3.7.5 allows out-of-bounds     access via a crafted archive file because src can move beyond dst. (CVE-2024-48957)
