Stack-based buffer overflow in telnet in Apple Mac OS X 10.4.11 and 10.5 before 10.5.7 allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via a long hostname for a telnet server.

Security readout for executives and security teams

This is an old Apple Mac OS X telnet flaw where an overly long telnet server hostname can crash the telnet application or potentially run attacker-controlled code. Business urgency is mainly for legacy Mac OS X 10.4.11 or 10.5 systems that still have telnet available or used. Exposure is likely limited to legacy Apple Mac OS X 10.4.11 and pre-10.5.7 10.5 systems where telnet is installed or used. The provided affected-product metadata is incomplete, but the CVE description names those Apple versions. Treat as a legacy-system risk. It is serious because code execution is listed, but urgency depends on whether affected Mac OS X versions still exist in the environment. Prioritize discovery, patch confirmation, and removal of telnet usage on obsolete hosts. Mitigation focus: Update affected Mac OS X 10.5 systems to 10.5.7 or vendor-supported guidance.; Apply Apple Security Update guidance for Mac OS X 10.4.11 where applicable.; Disable or remove telnet where it is not required..
