CVE-2017-12473

Summary: The CVE-2017-12473 entry concerns CCN-lite. The affected component is the function ccnl_ccntlv_bytes2pkt in CCN-lite, where processing packets can be coerced by input with “wrong L values.” The vulnerability allows context-dependent attackers to cause a denial of service via a crash. The...

CVE-2017-12466

CCN-lite before 2.00 allows context-dependent attackers to have unspecified impact via vectors related to sslhalen when running ccn-lite-sim, which trigger an out-of-bounds access...

CVE-2017-12463

Memory leak in the ccnlappRX function in ccnl-uapi.c in CCN-lite before 2.00 allows context-dependent attackers to cause a denial of service memory consumption via vectors involving an envelopes structure pointer when the packet format is unknown...

CVE-2017-12465

Multiple integer overflows in CCN-lite before 2.00 allow context-dependent attackers to have unspecified impact via vectors involving the 1 vallen variable in the iottlvparsesequence function or 2 typ, vallen and i variables in the localrpcparse function...

CVE-2017-12465

CCN-lite before 2.00 contains integer overflow flaws in iottlv_parse_sequence (vallen) and in localrpc_parse (typ, vallen, i), enabling context-dependent attackers to cause unspecified impact. Patch/upgrade to 2.0.0 is implied by the CNVD entry; no explicit exploit details or attacker workflow ar...

Type confusion

A type confusion issue was discovered in CCN-lite 2, leading to a memory access violation and a failure of the nonce feature which, for example, helped with loop prevention. ccnlfwdhandleInterest assumes that the union member s is of type ccnlpktdetailndntlvs. However, if the type is in fact stru...

CVE-2018-6480

CVE-2018-6480 describes a type confusion in CCN-lite 2. The bug occurs in ccnl_fwd_handleInterest, which assumes the union member s is of type ccnl_pktdetail_ndntlv_s; if the actual type is ccnl_pktdetail_ccntlv_s or ccnl_pktdetail_iottlv_s, the code may access uninitialized memory or data that i...
