 Mandriva Linux Security Advisory                         MDVSA-2015:205
 http://www.mandriva.com/en/support/security/
 _______________________________________________________________________

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

 Problem Description:

 Updated tor packages fix security vulnerabilities:

 disgleirio discovered that a malicious client could trigger an
 assertion failure in a Tor instance providing a hidden service,
 thus rendering the service inaccessible (CVE-2015-2928).

 DonnchaC discovered that Tor clients would crash with an assertion
 failure upon parsing specially crafted hidden service descriptors
 (CVE-2015-2929).

 Introduction points would accept multiple INTRODUCE1 cells on one
 circuit, making it inexpensive for an attacker to overload a hidden
 service with introductions. Introduction points now no longer allow
 multiple cells of that type on the same circuit.

 The tor package has been updated to version 0.2.4.27, fixing these
 issues.
