Ccn-lite Security Vulnerabilities

CVE-2018-12889

An issue was discovered in CCN-lite 2.0.1. There is a heap-based buffer overflow in mkAddToRelayCacheRequest and in ccnl_populate_cache for an array lacking '\0' termination when reading a binary CCNx or NDN file. This can result in Heap Corruption. This was addressed by fixing the memory...

CVE-2018-7039

CCN-lite 2.0.0 Beta allows remote attackers to cause a denial of service (buffer overflow) or possibly have unspecified other impact because the ccnl_ndntlv_prependBlob function in ccnl-pkt-ndntlv.c can be called with wrong arguments. Specifically, there is an incorrect integer data type causing a....

CVE-2018-6953

In CCN-lite 2, the Parser of NDNTLV does not verify whether a certain component's length field matches the actual component length, which has a resultant buffer overflow and out-of-bounds memory...

CVE-2018-6480

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). ccnl_fwd_handleInterest assumes that the union member s is of type ccnl_pktdetail_ndntlv_s. However, if the type is in...

CVE-2018-6948

In CCN-lite 2, the function ccnl_prefix_to_str_detailed can cause a buffer overflow, when writing a prefix to the buffer buf. The maximal size of the prefix is CCNL_MAX_PREFIX_SIZE; the buffer has the size CCNL_MAX_PREFIX_SIZE. However, when NFN is enabled, additional characters are written to the....

CVE-2017-12473

ccnl_ccntlv_bytes2pkt in CCN-lite allows context-dependent attackers to cause a denial of service (application crash) via vectors involving packets with "wrong L...

CVE-2017-12472

ccnl-ext-mgmt.c in CCN-lite before 2.00 allows context-dependent attackers to have unspecified impact by leveraging missing NULL pointer checks after...

CVE-2017-12412

ccn-lite-ccnb2xml in CCN-lite before 2.0.0 allows context-dependent attackers to have unspecified impact via a crafted file, which triggers infinite recursion and a stack...

CVE-2017-12469

Buffer overflow in util/ccnl-common.c in CCN-lite before 2.00 allows context-dependent attackers to have unspecified impact by leveraging incorrect memory...

CVE-2017-12463

Memory leak in the ccnl_app_RX 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 envelope_s structure pointer when the packet format is...

CVE-2017-12470

Integer overflow in the ndn_parse_sequence function in CCN-lite before 2.00 allows context-dependent attackers to have unspecified impact via vectors involving the typ and vallen...

CVE-2017-12466

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

CVE-2017-12468

Buffer overflow in ccn-lite-ccnb2xml.c in CCN-lite before 2.00 allows context-dependent attackers to have unspecified impact via vectors involving the vallen and len...

CVE-2017-12467

Memory leak in CCN-lite before 2.00 allows context-dependent attackers to cause a denial of service (memory consumption) by leveraging failure to allocate memory for the comp or complen structure...

CVE-2017-12471

The cnb_parse_lev function in CCN-lite before 2.00 allows context-dependent attackers to have unspecified impact by leveraging failure to check for out-of-bounds conditions, which triggers an invalid read in the hexdump...

CVE-2017-12464

ccn-lite-valid.c in CCN-lite before 2.00 allows context-dependent attackers to cause a denial of service (NULL pointer dereference) via vectors involving the keyfile...

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 iottlv_parse_sequence function or (2) typ, vallen and i variables in the localrpc_parse...
