DEBIAN-CVE-2012-1111

lightdm before 1.0.9 does not properly close file descriptors before opening a child process, which allows local users to write to the lightdm log or have other unspecified impact...

Connect Back 139 bytes

Connect Back 139 bytes. Shellcode exploit for linux platform / Title: connect back shellcode that splits from the process it was injected into, and then stays persistent and difficult to remove. It is also very close to invisible due to some interesting effects created by forking, and calling the...

stunnel: Information disclosure

Background The stunnel program is designed to work as an SSL encryption wrapper between a client and a local or remote server. Description stunnel does not properly update the state of the pseudo-random generator after fork-threading which causes subsequent children with the same process ID to us...

kernel: powerpc: tm: crash when forking inside a transaction

A flaw was found in the way the Linux kernel performed forking inside of a transaction. A local, unprivileged user on a PowerPC system that supports transactional memory could use this flaw to crash the system...

Stunnel <= 3.24, 4.00 Daemon Hijacking Proof of Concept Exploit

No description provided by source. / By Steve Grubb : The technique is simple. 1 Fork so that stunnel can't find you when it dies. 2 Send stunnel a SIGUSR2. Unhandled signals generally kill programs. Since you are a child of stunnel, the OS will deliver the signal. 3 Select on the leaked descript...

Possible TrueCrypt Fork in the Works

Although the developers behind the TrueCrypt encryption software have given up the ghost and decided to no longer maintain the application, interest in the project has never been higher. But, one of the developers says that a nascent effort to fork TrueCrypt is unlikely to succeed. Matthew Green,...

openSUSE Security Update : libssh (openSUSE-SU-2014:0366-1)

libssh was updated to fix a random generator reseeding issue when forking multiple servers. Forking multiple servers might under some circumstances get them the same random seed state. %NASLMINLEVEL 70300 C Tenable Network Security, Inc. The descriptive text and package checks in this plugin were...

DEBIAN-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...

USN-2145-1: libssh vulnerability

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...

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 process id getpid to the PRNG state, which is not guarante...

libssh -- PRNG state reuse on forking servers

Aris Adamantiadis reports: When accepting a new connection, the server 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 process id getpid to the PRNG state, which is not guaranteed to be unique...

SuSE 11.1 Security Update : ruby (SAT Patch Number 5716)

ruby: Properly initialize the random number generator when forking new process

Ruby before 1.8.6-p114 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...

ruby: Properly initialize the random number generator when forking new process

The SecureRandom.randombytes function in lib/securerandom.rb in Ruby before 1.8.7-p352 and 1.9.x before 1.9.2-p290 relies on PID values for initialization, which makes it easier for context-dependent attackers to predict the result string by leveraging knowledge of random strings obtained in an...
