[none]
Details

In CCN-lite 2, the function ccnlprefixtostrdetailed can cause a buffer overflow, when writing a prefix to the buffer buf. The maximal size of the prefix is CCNLMAXPREFIXSIZE; the buffer has the size CCNLMAXPREFIXSIZE. 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 CCNLMAXPREFIXSIZE can cause an overflow of buf inside ccnlprefixtostr_detailed.
