Details about the vulnerability can be found at the Augur blog. The summary for the vulnerability is:
A previously-unknown buffer overflow vulnerability in the Serpent compiler combined with Serpent’s un-enforced types and a bug in Serpent’s computation of memory addresses, caused a non-loss-of-funds vulnerability in the REP token contract. The vulnerability allows someone to increase the token creation timestamp indefinitely, thereby disabling transfers of the token. For a technical breakdown of the vulnerability, please read Zeppelin’s analysis.
