 Mandriva Linux Security Advisory                         MDVSA-2015:204
 http://www.mandriva.com/en/support/security/
 _______________________________________________________________________

 Package : librsync
 Date    : April 27, 2015
 Affected: Business Server 1.0
 _______________________________________________________________________

 Problem Description:

 Updated librsync packages fix security vulnerability:
 
 librsync before 1.0.0 used a truncated MD4 strong check sum to match
 blocks. However, MD4 is not cryptographically strong. It's possible
 that an attacker who can control the contents of one part of a file
 could use it to control other regions of the file, if it's transferred
 using librsync/rdiff (CVE-2014-8242).
 
 The change to fix this is not backward compatible with older versions
 of librsync. Backward compatibility can be obtained using the new
 rdiff sig --hash=md4 option or through specifying the signature magic
 in the API, but this should not be used when either the old or new
 file contain untrusted data.
 
 Also, any applications that use the librsync library will need to
 be recompiled against the updated library. The rdiff-backup packages
 have been rebuilt for this reason.
