A buffer overflow in PyCrypto might lead to the execution of arbitrary code when decrypting using ARC2.
PyCrypto is the Python Cryptography Toolkit.
Mike Wiacek of the Google Security Team reported a buffer overflow in the ARC2 module when processing a large ARC2 key length.
A remote attacker could entice a user or automated system to decrypt an ARC2 stream in an application using PyCrypto, possibly resulting in the execution of arbitrary code or a Denial of Service.
There is no known workaround at this time.
All PyCrypto users should upgrade to the latest version:
