Security readout for executives and security teams
CVE-2002-0004 is a local code execution flaw in the Unix/Linux at scheduling program. A malformed execution time can trigger heap corruption through a double-free condition. Business risk is concentrated on legacy systems where local shell users exist and the vulnerable at package remains unpatched. Most likely exposure is old Unix/Linux systems with at installed, especially distributions covered by the cited Debian, Red Hat, HP, SuSE, and Mandrake advisories. Exact affected versions are not provided in the bundle, so inventory and vendor advisory checks are required. Prioritize legacy server review rather than broad emergency response. This is old and local-only, but arbitrary code execution in a scheduling utility can matter where untrusted users, shared hosting, or stale Unix/Linux systems remain. Mitigation focus: Identify systems with the at package or /usr/bin/at installed.; Apply the relevant vendor security update for the operating system release.; Retire or isolate unsupported legacy hosts that cannot receive vendor fixes..
