CVE-2018-7039

Name of the Vulnerable Software and Affected Versions CCN-lite version 2.0.0 Beta

Description The issue allows remote attackers to cause a denial of service or possibly have other unspecified impacts. This is due to the ccnl ndntlv prependBlob function in ccnl-pkt-ndntlv.c being called with incorrect arguments, specifically an incorrect integer data type that can result in a negative third argument when processing crafted TLV data with inconsistent length information.

Recommendations For CCN-lite version 2.0.0 Beta, ensure that the ccnl ndntlv prependBlob function is called with correct arguments to prevent the denial of service or other potential impacts. As a temporary workaround, consider validating the TLV data for consistent length information before processing it with the ccnl ndntlv prependBlob function.
