A heap-based buffer overflow in PyCrypto might allow remote attackers to execute arbitrary code.
|Package||dev-python/pycrypto on all architectures|
|Affected versions||< 2.6.1-r2|
|Unaffected versions||>= 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"
