The version of grub2 installed on the remote host is prior to 2.06-14. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2025-2756 advisory.

    GNU GRUB (aka GRUB2) through 2.12 has a heap-based buffer overflow in fs/hfs.c via crafted sblock data in     an HFS filesystem. (CVE-2024-56737)

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

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

The remote Fedora 41 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2025-7b9adcd6ea advisory.

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

The CentOS Linux 8.4 host has packages installed that are affected by multiple vulnerabilities as referenced in the TuxCare CENTOS8.4:CLSA-2025:1744222859 advisory.

  - A flaw was found in the grub2-set-bootflag utility of grub2. After the fix of CVE-2019-14865, grub2-set-     bootflag will create a temporary file with the new grubenv content and rename it to the original grubenv     file. If the program is killed before the rename operation, the temporary file will not be removed and may     fill the filesystem when invoked multiple times, resulting in a filesystem out of free inodes or blocks.
    (CVE-2024-1048)

  - A flaw was found in grub2. A specially crafted JPEG file can cause the JPEG parser of grub2 to incorrectly     check the bounds of its internal buffers, resulting in an out-of-bounds write. The possibility of     overwriting sensitive information to bypass secure boot protections is not discarded. (CVE-2024-45774)

  - A flaw was found in grub2 where the grub_extcmd_dispatcher() function calls grub_arg_list_alloc() to     allocate memory for the grub's argument list. However, it fails to check in case the memory allocation     fails. Once the allocation fails, a NULL point will be processed by the parse_option() function, leading     grub to crash or, in some rare scenarios, corrupt the IVT data. (CVE-2024-45775)

  - A flaw was found in grub2. The calculation of the translation buffer when reading a language .mo file in     grub_gettext_getstr_from_position() may overflow, leading to a Out-of-bound write. This issue can be     leveraged by an attacker to overwrite grub2's sensitive heap data, eventually leading to the circumvention     of secure boot protections. (CVE-2024-45777)

  - A flaw was found in grub2. When reading tar files, grub2 allocates an internal buffer for the file name.
    However, it fails to properly verify the allocation against possible integer overflows. It's possible to     cause the allocation length to overflow with a crafted tar file, leading to a heap out-of-bounds write.
    This flaw eventually allows an attacker to circumvent secure boot protections. (CVE-2024-45780)

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

An update of the grub2 package has been released.

Tenable has extracted the preceding description block directly from the SUSE 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.

  - GNU GRUB (aka GRUB2) through 2.12 has a heap-based buffer overflow in fs/hfs.c via crafted sblock data in     an HFS filesystem. (CVE-2024-56737)

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