CWEhttps://cwe.mitre.org/data/definitions/835.html

An issue was discovered in dns.c in HAProxy through 1.8.14. In the case of a compressed pointer, a crafted packet can trigger infinite recursion by making the pointer point to itself, or create a long chain of valid pointers resulting in stack exhaustion.

Weakness

The product contains an iteration or loop with an exit condition that cannot be reached, i.e., an infinite loop.
