CVE-2003-0877: Mac OS X before 10.3 with core files enabled allows local users to overwrite arbitrary files and read core...

Security readout for executives and security teams

This old Mac OS X flaw affects systems before 10.3 when core dumps are enabled. A local user could abuse predictable core file creation in /cores to overwrite files or read crash data. The business risk is mainly legacy-host exposure with local account access. Exposure is likely limited to obsolete Mac OS X systems earlier than 10.3 with core files enabled and untrusted local users. The provided bundle does not identify affected CPEs or supported product branches. Treat this as a legacy-system hygiene issue unless affected hosts still exist. If pre-10.3 Mac OS X machines remain in sensitive environments, prioritize removal or isolation because local users could affect file integrity and expose crash data. Mitigation focus: Find and retire or upgrade Mac OS X systems older than 10.3.; Disable core file generation where operationally unnecessary.; Restrict local shell access to trusted users only..
