| Description | ION-DTN before 4.2.1-a.1 contains a denial of service vulnerability that allows unauthenticated remote attackers to crash the ION process by sending a BPv7 bundle with a zero-length payload. The canonicalizePayloadBlock() function in bpsec_util.c passes bundle->payload.length to zco_clone() without validating it against zero, causing a failed CHKZERO assertion that triggers sm_Abort() and terminates the process with SIGABRT before any HMAC verification occurs, requiring no valid key or credential to exploit. | |
| Title | ION-DTN < 4.2.1-a.1 Denial of Service via canonicalizePayloadBlock() Assertion | |
