SSL/TLS: CBC padding timing attack (lucky-13)

The TLS protocol 1.1 and 1.2 and the DTLS protocol 1.0 and 1.2, as used in OpenSSL, OpenJDK, PolarSSL, and other products, do not properly consider timing side-channel attacks on a MAC check requirement during the processing of malformed CBC padding, which allows remote attackers to conduct...

DEBIAN-CVE-2013-1620

The TLS implementation in Mozilla Network Security Services NSS does not properly consider timing side-channel attacks on a noncompliant MAC check operation during the processing of malformed CBC padding, which allows remote attackers to conduct distinguishing attacks and plaintext-recovery attac...

Slackware 9.0 : mod_ssl RSA blinding fixes (SSA:2003-141-05)

An upgrade for modssl to version 2.8.141.3.27 is now available. This version provides RSA blinding by default which prevents an extended timing analysis from revealing details of the secret key to an attacker. Note that this problem was already fixed within OpenSSL, so this is a 'double fix'. Wit...

USN-34-1: OpenSSH information leakage

@Mediaservice.net discovered two information leaks in the OpenSSH server. When using password authentication, an attacker could test whether a login name exists by measuring the time between failed login attempts, i. e. the time after which the "password:" prompt appears again. A similar issue...

ProFTPd 1.2.10 - Remote Users Enumeration

ProFTPd 1.2.10 - Remote Users Enumeration / Details Vulnerable Systems: ProFTPD Version 1.2.10 and below It is possible to determine which user names are valid, which are special, and which ones do not exist on the remote system. This can be accomplished by code execution path timing analysis...

ProFTPD Login Timing Account Name Enumeration

The remote ProFTPd server is as old or older than 1.2.10 It is possible to determine which user names are valid on the remote host based on timing analysis attack of the login procedure. An attacker may use this flaw to set up a list of valid usernames for a more efficient brute-force attack...

qpopper timing analysis on to determine if a username exists on a system

Hello, during development of a pop3 tool I found an issue that makes it possible for any user to check the validity of a user on a target system. If a user is valid and an invalid password has been supplied, then the system waits 10 seconds until it sends a disconnect message and disconnect. If t...

OpenSSL 0.9.x - CBC Error Information Leakage

OpenSSL 0.9.x - CBC Error Information Leakage source: https://www.securityfocus.com/bid/6884/info A side-channel attack against implementations of SSL exists that, through analysis of the timing of certain operations, can reveal sensitive information to an active adversary. This information leake...

Three problems in OpenSSH&#39;s ssh-keysign

This is being posted to bugtraq in the interest of full disclosure. Originally sent to [email protected]. There are 3 problems we observed by inspection of OpenSSH's ssh-keysign: 1 Charles Hannum Since no blinding is done on the RSA calculations, ssh-keysign is effectively a fairly efficient...
