The convert_to_decimal function in vasnprintf.c in Gnulib before 2018-09-23 has a heap-based buffer overflow because memory is not allocated for a trailing '\0' character during %f processing.

The Rocky Linux 9.6 host has packages installed that are affected by multiple vulnerabilities as referenced in the CIQ ciqsa-2026_1403 advisory.

    This advisory aggregates security fixes for the coreutils SRPM in CIQ LTS 9.6. It addresses 6 CVEs:
    CVE-2025-5278, CVE-2015-4041, CVE-2015-4042, CVE-2017-18018, CVE-2017-7476, and 1 more.

Tenable has extracted the preceding description block directly from the CIQ 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 remote NewStart CGSL host, running version MAIN 6.06 (SP), has coreutils packages installed that are affected by multiple vulnerabilities:

  - Gnulib before 2017-04-26 has a heap-based buffer overflow with the TZ environment variable. The error is     in the save_abbr function in time_rz.c. (CVE-2017-7476)

  - The keycompare_mb function in sort.c in sort in GNU Coreutils through 8.23 on 64-bit platforms performs a     size calculation without considering the number of bytes occupied by multibyte characters, which allows     attackers to cause a denial of service (heap-based buffer overflow and application crash) or possibly have     unspecified other impact via long UTF-8 strings. (CVE-2015-4041)

  - Integer overflow in the keycompare_mb function in sort.c in sort in GNU Coreutils through 8.23 might allow     attackers to cause a denial of service (application crash) or possibly have unspecified other impact via     long strings. (CVE-2015-4042)

  - In GNU Coreutils through 8.29, chown-core.c in chown and chgrp does not prevent replacement of a plain     file with a symlink during use of the POSIX -R -L options, which allows local users to modify the     ownership of arbitrary files by leveraging a race condition. (CVE-2017-18018)

  - The convert_to_decimal function in vasnprintf.c in Gnulib before 2018-09-23 has a heap-based buffer     overflow because memory is not allocated for a trailing '\0' character during %f processing.
    (CVE-2018-17942)
