Description:
A vulnerability has been reported in OpenBSD, which can be exploited by malicious, local users to cause a DoS (Denial of Service).
The vulnerability is caused due to a NULL pointer dereference error within the "ip_ctloutput()" function in sys/netinet/ip_output.c and the "ip6_ctloutput()" function in sys/netinet6/ip6_output.c. This can be exploited to crash an affected kernel by calling "getsockopt()" with e.g. IP_AUTH_LEVEL, IP_ESP_TRANS_LEVEL, IP_ESP_NETWORK_LEVEL, or IP_IPCOMP_LEVEL.
Note: Successful exploitation requires root privileges.
