Detailsinfo

A vulnerability was found in CCN-lite 2. It has been rated as critical. Affected by this issue is the function ccnl_prefix_to_str_detailed. The manipulation as part of a Packet leads to a memory corruption vulnerability. Using CWE to declare the problem leads to CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. Impacted is confidentiality, integrity, and availability. CVE summarizes:

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 buffer (e.g., the "NFN" and "R2C" tags). Therefore, sending an NFN-R2C packet with a prefix of size CCNL_MAX_PREFIX_SIZE can cause an overflow of buf inside ccnl_prefix_to_str_detailed.

The bug was discovered 02/13/2018. The weakness was published 02/13/2018 (GitHub Repository). The advisory is available at github.com. This vulnerability is handled as CVE-2018-6948 since 02/13/2018.
