Summary
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 negative third argument in some cases of crafted TLV data with inconsistent length information.
Exploit prediction
1.44% chance of exploitation in the next 30 days, higher than 73% of all scored CVEs (FIRST EPSS, 2026-11-09).
