CVE-2002-1563

CVE Author: NIST National Vulnerability Database (NVD)
Summary:

stunnel 4.0.3 and earlier allows attackers to cause a denial of service (crash) via SIGCHLD signal handler race conditions that cause an inconsistency in the child counter.

Exploitability Analysis:

This is a vulnerability exploitable with only local access requires the attacker to have either physical access to the vulnerable system or a local (shell) account. Examples of locally exploitable vulnerabilities are peripheral attacks such as Firewire/USB DMA attacks, and local privilege escalations (e.g., sudo).

Exploitability Complexity:

Specialized access conditions exist. For example, in most configurations, the attacking party must already have elevated privileges or spoof additional systems in addition to the attacking system (e.g., DNS hijacking). The attack depends on social engineering methods that would be easily detected by knowledgeable people. For example, the victim must perform several suspicious or atypical actions. The vulnerable configuration is seen very rarely in practice. If a race condition exists, the window is very narrow.

Authentication:

Authentication is not required to access and exploit the vulnerability.

Confidentiality Impact:

There is no impact to the confidentiality of the system.

Integrity Impact:

There is no impact to the integrity of the system.

Availability Impact:

There is reduced performance or interruptions in resource availability. An example is a network-based flood attack that permits a limited number of successful connections to an Internet service.
