Message-Id: <EF9FCE0A-71A0-47CF-8483-0F6ACEFC0A8B@7bits.nl> Date: Mon, 30 May 2011 20:30:38 +0200 From: Peter van Dijk <peter@...ts.nl> To: full-disclosure@...ts.grok.org.uk Subject: Leveraging pam_env to steal DSA keys Hello, regarding http://www.ubuntu.com/usn/usn-1140-1/ posted today (originally documented as http://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2010-3435), what the notices do not mention is that this attack, under certain circumstances, can lift enough key material from a private DSA key to reconstruct the whole key in feasible time. More information in my article at http://7bits.nl/projects/pamenv-dsakeys/pamenv-dsakeys.html Related blogpost at http://7bits.nl/blog/2011/05/30/from-symlinks-to-private-keys Comments or questions, please post a comment at the blog post or mail me privately.
