-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 _______________________________________________________________________ Mandriva Linux Security Advisory MDVSA-2015:125 http://www.mandriva.com/en/support/security/ _______________________________________________________________________ Package : tcpdump Date : March 29, 2015 Affected: Business Server 2.0 _______________________________________________________________________ Problem Description: Updated tcpdump package fixes security vulnerabilities: The Tcpdump program could crash when processing a malformed OLSR payload when the verbose output flag was set (CVE-2014-8767). The application decoder for the Ad hoc On-Demand Distance Vector (AODV) protocol in Tcpdump fails to perform input validation and performs unsafe out-of-bound accesses. The application will usually not crash, but perform out-of-bounds accesses and output/leak larger amounts of invalid data, which might lead to dropped packets. It is unknown if a payload exists that might trigger segfaults (CVE-2014-8769). It was discovered that tcpdump incorrectly handled printing PPP packets. A remote attacker could use this issue to cause tcpdump to crash, resulting in a denial of service, or possibly execute arbitrary code (CVE-2014-9140). Several vulnerabilities have been discovered in tcpdump. These vulnerabilities might result in denial of service (application crash) or, potentially, execution of arbitrary code (CVE-2015-0261, CVE-2015-2153, CVE-2015-2154, CVE-2015-2155). _______________________________________________________________________ References: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-8767 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-8769 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-9140 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2015-0261 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2015-2153 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2015-2154 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2015-2155 http://advisories.mageia.org/MGASA-2014-0503.html http://advisories.mageia.org/MGASA-2014-0511.html http://advisories.mageia.org/MGASA-2015-0114.html _______________________________________________________________________ Updated Packages: Mandriva Business Server 2/X86_64: 1180c018a9b5d69f4a1ca1ec2c401e4a mbs2/x86_64/tcpdump-4.4.0-0.2.mbs2.x86_64.rpm eef0acb6047e3127955be03f2ec91c88 mbs2/SRPMS/tcpdump-4.4.0-0.2.mbs2.src.rpm _______________________________________________________________________ To upgrade automatically use MandrivaUpdate or urpmi.
