Design/Logic Flaw

The random number feature in Linux kernel 2.6 before 2.6.20.13, and 2.6.21.x before 2.6.21.4, 1 does not properly seed pools when there is no entropy, or 2 uses an incorrect cast when extracting entropy, which might cause the random number generator to provide the same values after reboots on...

CVE-2006-3419

Tor before 0.1.1.20 uses OpenSSL pseudo-random bytes RANDpseudobytes instead of cryptographically strong RANDbytes, and seeds the entropy value at start-up with 160-bit chunks without reseeding, which makes it easier for attackers to conduct brute force guessing attacks...

CVE-2006-3419

CVE-2006-3419 affects Tor prior to 0.1.1.20. The issue stems from using OpenSSL RAND_pseudo_bytes instead of a cryptographically strong RAND_bytes, and seeding entropy at startup with 160-bit chunks without reseeding. This design makes brute-force guessing attacks more feasible for an attacker. M...

Mandrake Linux Security Advisory : perl-Net_SSLeay (MDKSA-2006:023)

Javier Fernandez-Sanguino Pena discovered that the perl Net::SSLeay module used the file /tmp/entropy as a fallback entropy source if a proper source was not set via the environment variable EGDPATH. This could potentially lead to weakened cryptographic operations if an attacker was able to provi...

/tmp/entropy file is used for entropy gathering if no entropy source is specified with EGDPATH envoronment variable. Attacker can fille file with known data...

Ubuntu 5.04 : libnet-ssleay-perl vulnerability (USN-113-1)

Javier Fernandez-Sanguino Pena discovered that this library used the file /tmp/entropy as a fallback entropy source if a proper source was not set in the environment variable EGDPATH. This can potentially lead to weakened cryptographic operations if an attacker provides a /tmp/entropy file with...

CVE-2005-3505

CVE-2005-3505 describes a cross-site scripting (XSS) flaw in the Entropy Chat script used by cPanel versions 10.2.0-R82 and 10.6.0-R137. The underlying issue is that a chat message containing JavaScript in style attributes within tags such as can be processed by Internet Explorer, enabling remot...

CVE-2005-0106

SSLeay.pm in libnet-ssleay-perl before 1.25 uses the /tmp/entropy file for entropy if a source is not set in the EGDPATH variable, which allows local users to reduce the cryptographic strength of certain operations by modifying the file...

CVE-2005-0106

CVE-2005-0106 affects the perl module libnet-ssleay-perl (SSLeay.pm) before 1.25. When no entropy source is set in EGD_PATH, it falls back to the file /tmp/entropy, which an attacker with write access to that file could modify to weaken cryptographic operations. Consequence: potential partial imp...

CVE-2003-0094

CVE-2003-0094 affects Mandrake Linux 8.2/9.0 util-linux mcookie. The patch changed the entropy source from /dev/random to /dev/urandom, making mcookie output more predictable and potentially aiding certain attacks. The Nessus advisory notes the patch was removed in these updates, restoring a bett...

Mandrake Linux Security Advisory : util-linux (MDKSA-2003:016)

The util-linux package provides the mcookie utility, a tool for generating random cookies that can be used for X authentication. The util-linux packages that were distributed with Mandrake Linux 8.2 and 9.0 had a patch that made it use /dev/urandom instead of /dev/random, which resulted in the...
