Section 3.2 says:

When n = 160, as is the case for SHA-1, it will
   take 2^106 computations to find a second pre-image in a 60-byte
   message.

It should say:

When n = 160, as is the case for SHA-1, the estimated computational
 complexity of finding a second preimage of any given message of 
about 2^60 bytes in length is 2^106 (compression function 
executions) which is significantly less than 2^160. 

Notes:

Clarification.

spt: I replaced 2^55 blocks with 2^60 bytes after some consultation with Lily and Quynh.
