- Date Reported:
- 24 Jun 2012
- Affected Packages:
- Security database references:
- In Mitre's CVE dictionary: CVE-2012-2417.
- More information:
It was discovered that that the ElGamal code in PythonCrypto, a collection of cryptographic algorithms and protocols for Python used insecure insufficient prime numbers in key generation, which lead to a weakened signature or public key space, allowing easier brute force attacks on such keys.
For the stable distribution (squeeze), this problem has been fixed in version 2.1.0-2+squeeze1.
For the unstable distribution (sid), this problem has been fixed in version 2.6-1.
We recommend that you upgrade your python-crypto packages. After installing this update, previously generated keys need to be regenerated.
