Iggy Frankovic discovered an ospfd crash when perfomring fuzzing of OSPF LSA packets. The crash occurs in ospf_te_parse_te() function when attemping to create corresponding egde from TE Link parameters. If there is no local address, an edge is created but without any attributes. During parsing, the function try to access to this attribute fields which has not been created causing an ospfd crash. The patch simply check if the te parser has found a valid local address. If not found, we stop the parser which avoid the crash. Signed-off-by: Olivier Dugeon <[email protected]> (cherry picked from commit a73e66d)
