openSUSE Security Update : tor (openSUSE-SU-2014:0143-1)

fixes potentially poor random number generation for users who 1 use OpenSSL 1.0.0 or later, 2 set 'HardwareAccel 1' in their torrc file, 3 have 'Sandy Bridge' or 'Ivy Bridge' Intel processors and 4 have no state file in their DataDirectory as would happen on first start. Users who generated relay...

CVE-2014-2251

The random-number generator on Siemens SIMATIC S7-1500 CPU PLC devices with firmware before 1.5.0 does not have sufficient entropy, which makes it easier for remote attackers to defeat cryptographic protection mechanisms and hijack sessions via unspecified vectors...

[SECURITY] Fedora 19 Update: numpy-1.7.2-8.fc19

NumPy is a general-purpose array-processing package designed to efficiently manipulate large multi-dimensional arrays of arbitrary records without sacrificing too much speed for small multi-dimensional arrays. NumPy is built on the Numeric code base and adds features introduced by numarray as wel...

MGASA-2014-0059 Updated tor package fixes security vulnerability

Tor before 0.2.4.20, when OpenSSL 1.x is used in conjunction with a certain HardwareAccel setting on Intel Sandy Bridge and Ivy Bridge platforms, does not properly generate random numbers for relay identity keys and hidden-service identity keys, which might make it easier for remote attackers to...

CVE-2013-7295

Tor before 0.2.4.20, when OpenSSL 1.x is used in conjunction with a certain HardwareAccel setting on Intel Sandy Bridge and Ivy Bridge platforms, does not properly generate random numbers for 1 relay identity keys and 2 hidden-service identity keys, which might make it easier for remote attackers...

Updated drupal package fixes security vulnerabilities

Drupal's form API has built-in cross-site request forgery CSRF validation, and also allows any module to perform its own validation on the form. In certain common cases, form validation functions may execute unsafe operations CVE-2013-6385. Drupal core directly used the mtrand pseudorandom number...

Debian Security Advisory DSA 2804-1 (drupal7 - several vulnerabilities)

Multiple vulnerabilities have been discovered in Drupal, a fully-featured content management framework: Cross-site request forgery, insecure pseudo random number generation, code execution, incorrect security token validation and cross-site scripting. In order to avoid the remote code execution...

Race condition

The Crypto.Random.atfork function in PyCrypto before 2.6.1 does not properly reseed the pseudo-random number generator PRNG before allowing a child process to access it, which makes it easier for context-dependent attackers to obtain sensitive information by leveraging a race condition in which a...

Scientific Linux Security Update : kernel on SL5.x i386/x86_64 (20131022)

A flaw was found in the way the Linux kernel handled the creation of temporary IPv6 addresses. If the IPv6 privacy extension was enabled /proc/sys/net/ipv6/conf/eth0/usetempaddr is set to '2', an attacker on the local network could disable IPv6 temporary address generation, leading to a potential...

PT-2013-02: Password Reset Token Prediction in FluxBB

The specialists of Positive Technologies have detected a "Password Reset Token Prediction" vulnerability in FluxBB. The vulnerability was detected in password reset token generation algorithm. FluxBB generates weak random numbers using mtrand function: function randomkey$len, $readable = false,...

Low Entropy RSA Issue in Intel EPSD Baseboard Management Controller (BMC) Firmware

Summary: There is a potential security vulnerability related to the improper generation of RSA encryption keys in EPSD Baseboard Management Controller BMC firmware. Intel is releasing updated versions of the BMC firmware to mitigate the potential vulnerability. Description: There is a potential...

Ruby Random Number Generation Local Denial Of Service Vulnerability

Ruby before 1.8.7-p352 does not reset the random seed upon forking, which makes it easier for context-dependent attackers to predict the values of random numbers by leveraging knowledge of the number sequence obtained in a different child process, a related issue to CVE-2003-0900. NOTE: this issu...

DEBIAN-CVE-2011-0766

The random number generator in the Crypto application before 2.0.2.2, and SSH before 2.0.5, as used in the Erlang/OTP ssh library before R14B03, uses predictable seeds based on the current time, which makes it easier for remote attackers to guess DSA host and SSH session keys...

Researchers Improve Random-Number Generation with Forced Memory 'Twitching'

A German research team has now developed a true random number generator that uses an extra layer of randomness by making a computer memory element, a flip-flop, twitch randomly between its two states 1 or 0. Immediately prior to the switch, the flip-flop is in a “metastable state” where its...

Improper access control

PowerDNS Recursor before 3.1.5 uses insufficient randomness to calculate 1 TRXID values and 2 UDP source port numbers, which makes it easier for remote attackers to poison a DNS cache, related to a algorithmic deficiencies in rand and random functions in external libraries, b use of a 32-bit seed...

BIND: Weak random number generation

Background ISC BIND is the Internet Systems Consortium implementation of the Domain Name System DNS protocol. Description Amit Klein from Trusteer reported that the random number generator of ISC BIND leads, half the time, to predictable 1 chance to 8 query IDs in the resolver routine or in zone...
