Technical details
A buffer overflow vulnerability exists within the crond daemon in Slackware Linux. The flaw is triggered during the processing of specific inputs, though the exact vulnerable parameter is not specified in the legacy advisory. Because crond typically runs with elevated privileges to manage system-wide tasks, a local attacker can exploit this memory corruption to execute arbitrary code with root permissions. This allows for a complete privilege escalation from a standard user to the system administrator. The vulnerability is accessible to any user with local shell access.
