  "cwe" : "CWE-121",
  "details" : [ "A stack-based buffer overflow exists in FreeIPMI's ipmi-oem tool, in the Dell OEM handler for the get-system-info cmc-ipv6-info subcommand. The vulnerable function _output_dell_system_info_cmc_ipv6_info uses a 256-byte stack buffer but allows up to 65536 bytes of data to be copied from a BMC response without proper bounds checking." ],
  "statement" : "This flaw has limited practical impact for several reasons: (1) ipmi-oem is a client-side command-line tool run manually by administrators, not a listening service or daemon — exploitation requires a user to actively run the specific Dell OEM subcommand against a compromised or malicious BMC; (2) IPMI communication typically occurs over a dedicated out-of-band management network, not the general Internet; (3) Red Hat Enterprise Linux builds FreeIPMI with full hardening enabled (_hardened_build 1), including stack protector (-fstack-protector-strong), which detects stack buffer corruption and terminates the process before the return address can be hijacked — effectively limiting the impact to a client-side crash rather than code execution; (4) additional mitigations including PIE, full RELRO, and NX further hinder exploitation even if the stack canary were bypassed.\nFix is available in FreeIPMI version 1.6.19.",
