-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 _______________________________________________________________________ Mandriva Linux Security Advisory MDVSA-2014:229 http://www.mandriva.com/en/support/security/ _______________________________________________________________________ Package : libvncserver Date : November 26, 2014 Affected: Business Server 1.0 _______________________________________________________________________ Problem Description: Updated libvncserver packages fix security vulnerabilities: A malicious VNC server can trigger incorrect memory management handling by advertising a large screen size parameter to the VNC client. This would result in multiple memory corruptions and could allow remote code execution on the VNC client (CVE-2014-6051, CVE-2014-6052). A malicious VNC client can trigger multiple DoS conditions on the VNC server by advertising a large screen size, ClientCutText message length and/or a zero scaling factor parameter (CVE-2014-6053, CVE-2014-6054). A malicious VNC client can trigger multiple stack-based buffer overflows by passing a long file and directory names and/or attributes (FileTime) when using the file transfer message feature (CVE-2014-6055). Additionally libvncserver has been built against the new system minilzo library which is also being provided with this advisory. _______________________________________________________________________ References: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-6051 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-6052 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-6053 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-6054 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-6055 http://advisories.mageia.org/MGASA-2014-0397.html _______________________________________________________________________ Updated Packages: Mandriva Business Server 1/X86_64: 4d938f964a86df6c1fb2aad9342db1e3 mbs1/x86_64/lib64lzo2_2-2.08-1.1.mbs1.x86_64.rpm 676ed246f1587fb815620e42a2e64e9a mbs1/x86_64/lib64lzo-devel-2.08-1.1.mbs1.x86_64.rpm d04fc1fb9b16142be0111f5efb276967 mbs1/x86_64/lib64minilzo0-2.08-1.1.mbs1.x86_64.rpm 84f52d51b3a28e5eecd8b0f7dd3c3b65 mbs1/x86_64/lib64vncserver0-0.9.9-1.mbs1.x86_64.rpm 50d5bf0cdff71f9773d07bfee2804eaf mbs1/x86_64/lib64vncserver-devel-0.9.9-1.mbs1.x86_64.rpm 70da4fa0a7eb955f45ed1fcd6fd4ca19 mbs1/x86_64/linuxvnc-0.9.9-1.mbs1.x86_64.rpm da9cbd99e5f15bbe8a0185e044b60c13 mbs1/SRPMS/liblzo-2.08-1.1.mbs1.src.rpm 6cf01a7cb6d388558f73d059340ed3da mbs1/SRPMS/libvncserver-0.9.9-1.mbs1.src.rpm _______________________________________________________________________ To upgrade automatically use MandrivaUpdate or urpmi.
