Synopsis

The remote Amazon Linux 2023 host is missing a security update.

Description

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2026-3134 advisory.

FreeIPMI before 1.6.19 has a stack-based buffer overflow in _ipmi_sel_oem_fujitsu_get_sel_entry_long_text in libfreeipmi/sel/ipmi-sel-string-fujitsu-irmc-common.c via malformed Fujitsu SEL long-text responses.
(CVE-2026-85504)

ipmi-oem in FreeIPMI before 1.6.19 has a stack-based buffer over-read in ipmi_oem_fujitsu_get_sel_entry_long_text in ipmi-oem/ipmi-oem-fujitsu.c when a BMC provides a short response, a different vulnerability than CVE-2026-50031 (which has different affected versions).
(CVE-2026-85505)

ipmi-oem in FreeIPMI before 1.6.19 has a stack-based buffer overflow in _get_dell_system_info_idrac_info in ipmi-oem/ipmi-oem-dell.c (idrac-info subcommand to dell get-system-info). (CVE-2026-85506)

ipmi-oem in FreeIPMI before 1.6.19 has a stack-based buffer overflow in _output_dell_system_info_cmc_info in ipmi-oem/ipmi-oem-dell.c (cmc-info subcommand to dell get-system-info). (CVE-2026-85507)

ipmi-oem in FreeIPMI before 1.6.19 has a stack-based buffer overflow in

FreeIPMI before 1.6.19 has a stack-based buffer overflow in _read_fru_data in libfreeipmi/fru/ipmi-fru.c when a BMC returns more bytes than requested. (CVE-2026-85509)

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

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

Solution

Run 'dnf update freeipmi --releasever 2023.12.20260928' or or 'dnf update --advisory ALAS2023-2026-3134 --releasever 2023.12.20260928' to update your system.
