Weaknesses (CWE)

CWE-835Loop with Unreachable Exit Condition ('Infinite Loop')

Description

libpcap BPF interpreter treats the offset in the 'ja L' BPF instruction as a signed integer to implement looping via backward jumps, but it does not limit the number of loop iterations. In particular uncommon use cases a crafted filter program can cause the interpreter to loop infinitely.
