-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 _______________________________________________________________________ Mandriva Linux Security Advisory MDVSA-2015:096 http://www.mandriva.com/en/support/security/ _______________________________________________________________________ Package : stunnel Date : March 28, 2015 Affected: Business Server 2.0 _______________________________________________________________________ Problem Description: Updated stunnel package fixes security vulnerability: A flaw was found in the way stunnel, a socket wrapper which can provide SSL support to ordinary applications, performed (re)initialization of PRNG after fork. When accepting a new connection, the server forks and the child process handles the request. The RAND_bytes() function of openssl doesn't reset its state after the fork, but seeds the PRNG with the output of time(NULL). The most important consequence is that servers using EC (ECDSA) or DSA certificates may under certain conditions leak their private key (CVE-2014-0016). The updated packages fix this issue by using threads instead of new processes to handle connections. Also an issue has been corrected where the directory for the pid file was not being created when the package is installed. An issue currently exists in Mageia 4 where it fails trying to use FIPS SSL (mga#13124). This can be worked around by adding fips = no into the config. _______________________________________________________________________ References: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-0016 http://advisories.mageia.org/MGASA-2014-0144.html _______________________________________________________________________ Updated Packages: Mandriva Business Server 2/X86_64: 34c6ac327fa19ff94e3461e65b82518d mbs2/x86_64/stunnel-4.56-4.1.mbs2.x86_64.rpm 90de576bd2fb8b349c9fe373db32cac6 mbs2/SRPMS/stunnel-4.56-4.1.mbs2.src.rpm _______________________________________________________________________ To upgrade automatically use MandrivaUpdate or urpmi.
