CVE-2012-5508

The error pages in Plone before 4.2.3 and 4.3 before beta 1 allow remote attackers to obtain random numbers and derive the PRNG state for password resets via unspecified vectors. NOTE: this identifier was SPLIT per ADT2 due to different vulnerability types. CVE-2012-6661 was assigned for the PRNG...

CVE-2012-5508

CVE-2012-5508 (and related CVE-2012-6661) affects Zope before 2.13.19 used with Plone older than 4.2.3 and Plone 4.3 beta1. Root cause: PRNG not reseeded, enabling remote attackers to infer PRNG state and potentially abuse password resets via unspecified vectors. Mitigation: upgrade to Zope 2.13....

CVE-2012-6661

CVE-2012-6661 affects Zope before 2.13.19 as used in Plone before 4.2.3 and in 4.3 before beta 1, where the PRNG is not reseeded, allowing remote attackers to guess random numbers via unspecified vectors. The issue was split from CVE-2012-5508 (ADT2). Public references indicate remediation by upg...

FreeBSD : libssh -- PRNG state reuse on forking servers (f8c88d50-5fb3-11e4-81bd-5453ed2e2b49)

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...

GLSA-201408-03 : LibSSH: Information disclosure

The remote host is affected by the vulnerability described in GLSA-201408-03 LibSSH: Information disclosure A new connection inherits the state of the PRNG without re-seeding with random data. Impact : Servers using ECC ECDSA or DSA certificates in non-deterministic mode may under certain...

LibSSH: Information disclosure

Background LibSSH is a C library providing SSHv2 and SSHv1. Description A new connection inherits the state of the PRNG without re-seeding with random data. Impact Servers using ECC ECDSA or DSA certificates in non-deterministic mode may under certain conditions leak their private key. Workaround...

LibreSSL PRNG Vulnerability Patched

The OpenBSD project late last night rushed out a patch for a vulnerability in the LibreSSL pseudo random number generator PRNG. The flaw was disclosed two days ago by the founder of secure backup company Opsmate, Andrew Ayer, who said the vulnerability was a “catastrophic failure of the PRNG.”...

Early Review of LibreSSL Finds Problematic PRNG

When the OpenBSD foundation sent LibreSSL out the door last weekend, it was with the full intention of getting some feedback and scrutiny in return, all in the name of making the crypto library stable and secure. What they likely didn’t expect were claims surfacing that LibreSSL shared some of th...
