Vulnerability details
The vulnerability allows a local attacker to gain elevated privileges on the target system.
The weakness exists in the hesiod_init function in lib/hesiod.c due to comparing EUID with UID to determine whether to use configurations from environment variables. A local attacker can gain root privileges via the (1) HESIOD_CONFIG or (2) HES_DOMAIN environment variable and leveraging certain SUID/SGUID binary.
