The version of ping used in OpenBSD is not affected by the issue found in FreeBSD (the vulnerability exists in the new implementation of the pr_pack() function, rewritten by FreeBSD developers in 2019), but during the review, another bug was uncovered that had gone unnoticed for 24 years. This bug leads to an infinite loop when processing a response with a zero-length option field in the IP packet. The fix has already been included in OpenBSD. The issue is not considered a vulnerability, as the network stack in the OpenBSD kernel does not allow such packets into user space.<br \/>\n<br \/>Source: <a content=\"nofollow\" rel=\"nofollow\"
