Synopsis
========
A flaw in PyCrypto allow remote attackers to obtain sensitive
information.
Background
==========
PyCrypto is the Python Cryptography Toolkit.
Affected packages
=================
——————————————————————-
Package / Vulnerable / Unaffected
——————————————————————-
1 dev-python/pycrypto <= 2.6.1-r2 Vulnerable!
——————————————————————-
NOTE: Certain packages are still vulnerable. Users should migrate
to another package if one is available or wait for the
existing packages to be marked stable by their
architecture maintainers.
Description
===========
It was discovered that PyCrypto incorrectly generated ElGamal key
parameters.
Impact
======
Attackers may be able to obtain sensitive information by reading
ciphertext data.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
Gentoo has discontinued support for PyCrypto. We recommend that users
unmerge PyCrypto:
# emerge –unmerge “dev-python/pycrypto”
NOTE: The Gentoo developer(s) maintaining PyCrypto have discontinued
support at this time. PyCryptodome is the canonical successor to
PyCrypto.
