Name of the Vulnerable Software and Affected Versions stunnel versions prior to 5.00 stunnel versions prior to 5.02 Description The issue is related to the improper update of the OpenSSL pseudo-random number generator PRNG state when using fork threading in stunnel. This causes subsequent childre...

CVE-2014-0016: Insufficient Entropy in PRNG

stunnel before 5.00, when using fork threading, does not properly update the state of the OpenSSL pseudo-random number generator PRNG, which causes subsequent children with the same process ID to use the same entropy pool and allows remote attackers to obtain private keys for EC ECDSA or DSA...

CVE-2014-0017

The RANDbytes function in libssh before 0.6.3, when forking is enabled, does not properly reset the state of the OpenSSL pseudo-random number generator PRNG, which causes the state to be shared between children processes and allows local users to obtain sensitive information by leveraging a pid...

CVE-2014-0017

CVE-2014-0017 affects libssh prior to 0.6.3 where RAND_bytes state is not re-seeded after fork, causing PRNG state to be shared between child processes. This can lead to leakage of private keys for servers using ECC (ECDSA) or DSA certificates under certain conditions. The issue is resolved by up...

Debian DSA-2879-1 : libssh - security update

It was discovered that libssh, a tiny C SSH library, did not reset the state of the PRNG after accepting a connection. A server mode application that forks itself to handle incoming connections could see its children sharing the same PRNG state, resulting in a cryptographic weakness and possibly...

Mandriva Linux Security Advisory : libssh (MDVSA-2014:053)

Updated libssh package fixes security vulnerability : When using libssh before 0.6.3, a libssh-based server, when accepting a new connection, forks and the child process handles the request. The RANDbytes function of openssl doesn't reset its state after the fork, but simply adds the current...

Ubuntu 12.04 LTS / 12.10 / 13.10 : libssh vulnerability (USN-2145-1)

Aris Adamantiadis discovered that libssh allowed the OpenSSL PRNG state to be reused when implementing forking servers. This could allow an attacker to possibly obtain information about the state of the PRNG and perform cryptographic attacks. Note that Tenable Network Security has extracted the...

Weak Early Random PRNG Threatens iOS 7 Kernel Mitigations

VANCOUVER – A revamped early random number generator in iOS 7 is weaker than its vulnerable predecessor and generates predictable outcomes. A researcher today at CanSecWest said an attacker could brute force the Early Random PRNG used by Apple in its mobile operating system to bypass a number of...

Stunnel PRING初始化漏洞

Bugtraq ID:65964 CVE ID:CVE-2014-0016 Stunnel是一个自由的跨平台软件，用于提供全局的TLS / SSL 服务。 Stunnel存在安全漏洞，套接字封装程序可对普通应用程序提供SSL支持，在fork后执行PRNG初始化，当接受新连接时，服务器fork，子进程处理请求。OpenSSLRANDbytes函数在fork后没有重置其状态，而是简单的添加当前进程IDgetpid至PRNG状态，可导致使用EC ECDSA或DSA证书的服务器在某些情况下泄漏私钥。 0 Stunnel 目前没有详细解决方案提供： http://www.stunnel.org...
