Vulnerabilities

An issue was discovered in CCN-lite 2.0.1.

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 wr…

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 accesses.

In CCN-lite 2, the function ccnl_prefix_to_str_detailed can cause a buffer overflow, when writing a prefix to the buffer buf.

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 values."

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 ccnl_malloc.

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…

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 variables.

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 allocation.

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 variables.

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 member.

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 access.

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…

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 variable.

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 wh…

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 overflow.

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).
