VNC authentication weakness
VNC authentication weakness --------------------------- VNC uses a DES-encrypted challenge-response system to avoid passing passwords over the wire in plaintext. However, it seems that a weakness in the way the challenge is generated by some servers would make this useless. The following program...
CVE-2001-0950
CVE-2001-0950 concerns the ValiCert Enterprise Validation Authority (EVA) Administration Server, version 3.3–4.2.1. The root cause is the use of insufficiently random data: session tokens for HSMs are generated with the C rand() function, and certificate/key generation may rely on /dev/urandom in...
CVE-2001-0950
ValiCert Enterprise Validation Authority EVA Administration Server 3.3 through 4.2.1 uses insufficiently random data to 1 generate session tokens for HSMs using the C rand function, or 2 generate certificates or keys using /dev/urandom instead of another source which blocks when the entropy pool ...
Re: More problems with RADIUS (protocol and implementations)
I note that the original message didn't cite my short message to Bugtraq about security issues with RADIUS: http://cert.uni-stuttgart.de/archive/bugtraq/2000/12/msg00332.html Some points in that message were also covered by Joshua, he added a number of good points, and missed a few others...
Keys generated with PGP5i batch mode do not contain sufficient randomness on systems that use /dev/random
Overview Under certain circumstances, PGP v5.0 generates keys that are not sufficiently random, which may allow an attacker to predict keys and, hence, recover information encrypted with that key. Description Generating Randomness in PGP Keys In order to generate cryptographically secure keys, PG...
CVE-2000-0445
The CVE-2000-0445 issue affects PGP 5.x on Unix-like systems where non-interactive (batch) key generation via pgpk can use insufficient randomness collected from /dev/random. The root cause is how PGP v5.0 processes entropy when generating keys in unattended mode, potentially producing weak, pred...
