The code for IPv6 fragment reassembly tries to access a previous fragment starting from a network incoming fragment that still doesn't have a reference to the previous one (which supposedly resides in the reassembly list). When faced with an incoming fragment that belongs to a non-empty fragment list, IPv6 reassembly must check that there are no empty holes between the fragments: this leads to an uninitialized pointer dereference in _fnet_ip6_reassembly in fnet_ip6.c, and causes Denial-of-Service." } ] }, "problemtype": { "problemtype_data": [ { "description": [ { "lang": "eng", "value": "n/a" } ] } ] }, "references": { "reference_data": [ { "refsource": "MISC", "name": "https://www.kb.cert.org/vuls/id/815128", "url": "https://www.kb.cert.org/vuls/id/815128" }, { "refsource": "MISC", "name": "https://us-cert.cisa.gov/ics/advisories/icsa-20-343-01", "url": "https://us-cert.cisa.gov/ics/advisories/icsa-20-343-01" }, { "refsource": "CONFIRM", "name": "http://fnet.sourceforge.net/manual/fnet_history.html", "url": "http://fnet.sourceforge.net/manual/fnet_history.html" } ] } }
