-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 _______________________________________________________________________ Mandriva Linux Security Advisory MDKSA-2007:203 http://www.mandriva.com/security/ _______________________________________________________________________ Package : xen Date : November 1, 2007 Affected: 2007.0, 2007.1, Corporate 4.0 _______________________________________________________________________ Problem Description: Tavis Ormandy discovered a heap overflow flaw during video-to-video copy operations in the Cirrus VGA extension code that is used in Xen. A malicious local administrator of a guest domain could potentially trigger this flaw and execute arbitrary code outside of the domain (CVE-2007-1320). Tavis Ormandy also discovered insufficient input validation leading to a heap overflow in the NE2000 network driver in Xen. If the driver is in use, a malicious local administrator of a guest domain could potentially trigger this flaw and execute arbitrary code outside of the domain (CVE-2007-1321, CVE-2007-5729, CVE-2007-5730). Steve Kemp found that xen-utils used insecure temporary files within the xenmon tool that could allow local users to truncate arbitrary files (CVE-2007-3919). Joris van Rantwijk discovered a flaw in Pygrub, which is used as a boot loader for guest domains. A malicious local administrator of a guest domain could create a carefully-crafted grub.conf file which could trigger the execution of arbitrary code outside of that domain (CVE-2007-4993). Updated packages have been patched to prevent these issues. _______________________________________________________________________ References: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-1320 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-1321 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-3919 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-4993 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-5729 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-5730 _______________________________________________________________________ Updated Packages: Mandriva Linux 2007.0: 70b7495f9eb6597b8dcff92a6a698a28 2007.0/i586/xen-3.0.3-0.20060703.3.1mdv2007.0.i586.rpm c939b93cb67251235a9c8f2824609702 2007.0/SRPMS/xen-3.0.3-0.20060703.3.1mdv2007.0.src.rpm Mandriva Linux 2007.0/X86_64: f35d3563e67a0a887c439657b2e29afb 2007.0/x86_64/xen-3.0.3-0.20060703.3.1mdv2007.0.x86_64.rpm c939b93cb67251235a9c8f2824609702 2007.0/SRPMS/xen-3.0.3-0.20060703.3.1mdv2007.0.src.rpm Mandriva Linux 2007.1: 183ef09d8ed8171adc894cbb606f922f 2007.1/i586/xen-3.0.3-0.20060703.5.1mdv2007.1.i586.rpm f4a0bfc9c6d5ae01664c8a906580b873 2007.1/SRPMS/xen-3.0.3-0.20060703.5.1mdv2007.1.src.rpm Mandriva Linux 2007.1/X86_64: c05336d0eef357b2b2c191286c4d679e 2007.1/x86_64/xen-3.0.3-0.20060703.5.1mdv2007.1.x86_64.rpm f4a0bfc9c6d5ae01664c8a906580b873 2007.1/SRPMS/xen-3.0.3-0.20060703.5.1mdv2007.1.src.rpm Corporate 4.0: ec6876abb87e57d61257f3b3c6659c22 corporate/4.0/i586/xen-3.0.1-3.1.20060mlcs4.i586.rpm 72a302b77a88766cc43276e431dabf79 corporate/4.0/SRPMS/xen-3.0.1-3.1.20060mlcs4.src.rpm Corporate 4.0/X86_64: 894c37bcf10d4ec8973ed11a5613aeb5 corporate/4.0/x86_64/xen-3.0.1-3.1.20060mlcs4.x86_64.rpm 72a302b77a88766cc43276e431dabf79 corporate/4.0/SRPMS/xen-3.0.1-3.1.20060mlcs4.src.rpm _______________________________________________________________________ To upgrade automatically use MandrivaUpdate or urpmi.
