Medienbericht

infinte loop in libpcap before 1.10.7

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.
