Description

This security bulletin contains information about 3 secuirty vulnerabilities.

1) Null pointer dereference (CVE-ID: CVE-2018-18065)

The vulnerability allows a remote authenticated attacker to cause DoS condition on the target system.

The vulnerability exists in the _set_key() function, as defined in the agent/helpers/table_container.c source code file due to a NULL pointer exception bug. A remote attacker can send a malicious UDP packet, trigger a NULL pointer dereference condition, cause the application to crash.

2) Remote code execution (CVE-ID: CVE-2018-1000116)

The vulnerability allows a remote unauthenticated attacker to execute arbitrary code on the target system.

The weakness exists due to insufficient handling of UDP packets. A remote attacker can submit a specially crafted UDP packet and execute arbitrary code.

Successful exploitation of the vulnerability may result in system compromise.

3) Stack-based buffer overflow (CVE-ID: CVE-2025-26336)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error. A remote attacker can trick the victim into performing unspecified actions on the system to trigger a stack-based buffer overflow and execute arbitrary code on the target system.
