CVE-2007-1398 medium priority: Ubuntu including 1 source packages (snort), 4 status rows across 4 suites (dapper, edgy, feisty, upstream): not-affected 3, needs-triage 1.
The frag3 preprocessor in Snort 2.6.1.1, 2.6.1.2, and 2.7.0 beta, when configured for inline use on Linux without the ip_conntrack module loaded, allows remote attackers to cause a denial of service (segmentation fault and application crash) via certain UDP packets produced by send_morefrag_packet and send_overlap_packet.
