CVE-2021-36762
An issue was discovered in HCC Embedded InterNiche NicheStack through 4.3. The tfshnd():tftpsrv.c TFTP packet processing function doesn’t ensure that a filename is adequately ‘{$content}’ terminated; therefore, a subsequent call to strlen for the filename might read out of bounds of the protocol packet buffer (if no ‘{$content}’ byte exists within a reasonable range).
