The Solaris pollset feature in the Event Port backend in poll/unix/port.c in the Apache Portable Runtime (APR) library before 1.3.9, as used in the Apache HTTP Server before 2.2.14 and other products, does not properly handle errors, which allows remote attackers to cause a denial of service (daemon hang) via unspecified HTTP requests, related to the prefork and event MPMs.

CWE
Deadlock
mitre_cwe·CVSS 2.1
[LOW] CWE-833 Deadlock
CWE-833: Deadlock
The product contains multiple threads or executable segments that are waiting for each other to release a necessary lock, resulting in deadlock.
Modes of Introduction:
Phase: Implementation
Common Consequences:
Scope: Availability. Impact: DoS: Resource Consumption (CPU), DoS: Resource Consumption (Other), DoS: Crash, Exit, or Restart. Each thread of execution will "hang" and prevent tasks from completing. In some cases, CPU consumption may occur if a lock check occurs in a tight loop.
Detection Methods:
Automated Static Analysis: Automated static analysis, commonly referred to as Static Application Security Testing (SAST), can find some instances of this weakness by analyzing source code (or binary/compiled code) without having to execute it. Typically, this is done
CWE
Improper Locking
mitre_cwe
CWE-667 Improper Locking
CWE-667: Improper Locking
The product does not properly acquire or release a lock on a resource, leading to unexpected resource state changes and behaviors.
Locking is a type of synchronization behavior that ensures that multiple independently-operating processes or threads do not interfere with each other when accessing the same resource. All processes/threads are expected to follow the same steps for locking. If these steps are not followed precisely - or if no locking is done at all - then another process/thread could modify the shared resource in a way that is not visible or predictable to the original process. This can lead to data or memory corruption, denial of service, etc.
