CVE-2010-1173: Input Validation

First published: Thu Apr 22 2010(Updated: )

Description of problem: Reported by Nokia-CN-Flexi via Issue Tracker. A similar issue was reported by Jukka Taimisto and Olli Jarva from the CROSS open source testing project at Codenomicon Ltd. This was also reported by Windriver on behalf of their customer via vendor-sec. Kernel crash occurs if sctp listening port receives malformatted init packet. Its an skb_over_panic BUG halt that results from processing an init chunk in which too many of its variable length parameters are in some way malformed. The problem is in sctp_process_unk_param: if (NULL == *errp) *errp = sctp_make_op_error_space(asoc, chunk, ntohs(chunk->chunk_hdr->length)); if (*errp) { sctp_init_cause(*errp, SCTP_ERROR_UNKNOWN_PARAM, WORD_ROUND(ntohs(param.p->length))); sctp_addto_chunk(*errp, WORD_ROUND(ntohs(param.p->length)), param.v); When we allocate an error chunk, we assume that the worst case scenario requires that we have chunk_hdr->length data allocated, which would be correct nominally, given that we call sctp_addto_chunk for the violating parameter. Unfortunately, we also, in sctp_init_cause insert a sctp_errhdr_t structure into the error chunk, so the worst case situation in which all parameters are in violation requires chunk_hdr->length+(sizeof(sctp_errhdr_t)*param_count) bytes of data. This fix solves the problem by allowing our implementation to only report a fixed number of errors. When we encounter an error in parameter processing we allocate a chunk that is min(asoc->pathmtu, SCTP_DEFAULT_MAXSEGMENT), limiting our error reporting to a single mtu sized chunk. Parameter errors that grow beyond that value are discarded.
