-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 _______________________________________________________________________ Mandriva Linux Security Advisory MDVSA-2015:165 http://www.mandriva.com/en/support/security/ _______________________________________________________________________ Package : bind Date : March 29, 2015 Affected: Business Server 2.0 _______________________________________________________________________ Problem Description: Updated bind packages fix security vulnerabilities: By making use of maliciously-constructed zones or a rogue server, an attacker can exploit an oversight in the code BIND 9 uses to follow delegations in the Domain Name Service, causing BIND to issue unlimited queries in an attempt to follow the delegation. This can lead to resource exhaustion and denial of service (up to and including termination of the named server process) (CVE-2014-8500). Jan-Piet Mens discovered that the BIND DNS server would crash when processing an invalid DNSSEC key rollover, either due to an error on the zone operator's part, or due to interference with network traffic by an attacker. This issue affects configurations with the directives "dnssec-lookaside auto;" (as enabled in the Mandriva default configuration) or "dnssec-validation auto;" (CVE-2015-1349). _______________________________________________________________________ References: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-8500 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2015-1349 http://advisories.mageia.org/MGASA-2014-0524.html http://advisories.mageia.org/MGASA-2015-0082.html _______________________________________________________________________ Updated Packages: Mandriva Business Server 2/X86_64: a2cf83873b09b47275d0030063a236c8 mbs2/x86_64/bind-9.10.1.P2-7.mbs2.x86_64.rpm 83d97de0884ef84b933cb06bfbbce24a mbs2/x86_64/bind-devel-9.10.1.P2-7.mbs2.x86_64.rpm 633a8a160c3be4dda5f134550288df8f mbs2/x86_64/bind-doc-9.10.1.P2-7.mbs2.noarch.rpm 40760cee0f0c97261b80d159ab60cb32 mbs2/x86_64/bind-sdb-9.10.1.P2-7.mbs2.x86_64.rpm ec17a87a3d0e50c4a1c33c84adc0c08b mbs2/x86_64/bind-utils-9.10.1.P2-7.mbs2.x86_64.rpm 95f44b351208cfcbf15108dc707b0f21 mbs2/SRPMS/bind-9.10.1.P2-7.mbs2.src.rpm _______________________________________________________________________ To upgrade automatically use MandrivaUpdate or urpmi.
