PyCrypto: Remote execution of arbitrary code A heap-based buffer overflow in PyCrypto might allow remote attackers to execute arbitrary code. pycrypto 2017-02-20 2017-02-20 576494 remote 2.6.1-r2 2.6.1-r2

The Python Cryptography Toolkit (PyCrypto) is a collection of both secure hash functions (such as SHA256 and RIPEMD160), and various encryption algorithms (AES, DES, RSA, ElGamal, etc.).

A heap-based buffer overflow vulnerability has been discovered in PyCrypto. Please review the CVE identifier referenced below for details.

A remote attacker, able to control the mode of operation in PyCrypto’s AES module, could possibly execute arbitrary code with the privileges of the process or cause a Denial of Service condition.

There is no known workaround at this time.

All PyCrypto users should upgrade to the latest version:

# emerge --sync # emerge --ask --oneshot --verbose ">=dev-python/pycrypto-2.6.1-r2"
