Title: Linux Deep Symbolic Link Denial of Service Vulnerability
Severity: MODERATE
Description:
A denial-of-service vulnerability exists in several versions of the Linux kernel.
The problem occurs when a user with local access creates a long chain of symbolically linked files. When the kernel dereferences the symbolic links, the process scheduler is blocked, effecively locking the system until the dereferencing is complete.
