What is CVE-2011-1547?

Multiple stack consumption vulnerabilities exist in the NetBSD kernel related to IPsec functionality. When IPsec is enabled, remote attackers can exploit these vulnerabilities by sending carefully crafted IPv4 or IPv6 packets containing nested IPComp headers. This can lead to denial of service situations such as memory corruption or kernel panic, potentially affecting system availability. It is crucial for users of affected NetBSD versions to patch their systems to mitigate these vulnerabilities.
