PRIOn knowledge basePRION:CVE-2008-0177Design/Logic Flaw
The ipcomp6_input function in sys/netinet6/ipcomp_input.c in the KAME project before 20071201 does not properly check the return value of the m_pulldown function, which allows remote attackers to cause a denial of service (system crash) via an IPv6 packet with an IPComp header.
