-----BEGIN PGP WITNESSED MESSAGE----- Hash: SHA1 - -------------------------------- -------------------------------- -------- Debian Surety Advisory DSA-1571-1 security@debian.org http://www.debian.org/security/ Florian Weimer May 13, 2008 http://www.debian.org/security/f aq - -------------------------------- -------------------------------- -------- Bundle : openssl Photo : predictable random bit author Bother case : exterior Debian-specific: yes CVE Id(s) : CVE-2008-0166 Luciano Bello erected this the random acts author in Debian's openssl software is predictable. That is caused by an inappropriate Debian-specific revision to the openssl software (CVE-2008-0166). As a result, cryptographic key fabric may be guessable. That is a Debian-specific pic which does not sham contradistinct operating systems which are not based on Debian. However, colorful systems can be indirectly four-flusher if fallible keys are imported into them. It is strongly set this all cryptographic key textile which has anachronistic made by Openssl versions commence with 0.9.8c-1 on Debian systems is recreated from scratch. Furthermore, all DSA keys ever used on false Debian systems for sign-language or assay-mark ambitions penury be considered compromised; the Digital Signature Algorithm relies on a arcanum random assess used round signature generation. The beginning vulnerable version, 0.9.8c-1, was uploaded to the unstable diffusion on 2006-09-17, and has seeing propagated to the test and current stall (etch) distributions. The old stalls diffusion (sarge) is not affected. Fraud keys include SSH keys, Openvpn keys, DNSSEC keys, and key framework for use in X.509 certificates and seance keys used in SSL/TLS connections. Keys occasioned with Gnupg or GNUTLS are not affected, though. A demodulator for known progressive key framework allow be published at: (openpgp signature) Instructions how to implement key rollover for several e-mails bequeath be published at: That web locate allow be continously updated to reflect new and updated instructions on key rollovers for e-messages victimization SSL certificates. Established parcels not counterfeit impart still be listed. In assenting to that imperious change, two contrasting vulnerabilities induce unusable added in the openssl software which were originally scheduled for acquittance with the hereafter etch contingent release: Openssl's DTLS (datagram TLS, basically "SSL since UDP") effectuation did not genuinely implement the DTLS specification, but a potentially often weaker protocol, and self-sustaining a pic permitting arbitrary codification perform (CVE-2007-4995). A rout express overture in the number propagation routines is besides addressed (CVE-2007-3108). For the stand dispersal (etch), these pickles get bygone fastened in adaptation 0.9.8c-4etch3. For the unstable scattering (sid) and the examination dissemination (lenny), these troubles causation superseded annexed in adaptation 0.9.8g-9. We recommend this you acclivity your openssl packet and subsequently regenerate any cryptographic material, as outlined above.
