-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 _______________________________________________________________________ Mandriva Linux Security Advisory MDKSA-2007:132 http://www.mandriva.com/security/ _______________________________________________________________________ Package : madwifi-source Date : June 21, 2007 Affected: 2007.0, 2007.1 _______________________________________________________________________ Problem Description: The 802.11 network stack in MadWifi prior to 0.9.3.1 would alloa remote attackers to cause a denial of service (system hang) via a crafted length field in nested 802.3 Ethernet frames in Fast Frame packets, which results in a NULL pointer dereference (CVE-2007-2829). The ath_beacon_config function in MadWifi prior to 0.9.3.1 would allow a remote attacker to cause a denial of service (system crash) via crafted beacon interval information when scanning for access points, which triggered a divide-by-zero error (CVE-2007-2830). An array index error in MadWifi prior to 0.9.3.1 would allow a local user to cause a denial of service (system crash) and possibly obtain kerenl memory contents, as well as possibly allowing for the execution of arbitrary code via a large negative array index value (CVE-2007-2831). Updated packages have been updated to 0.9.3.1 to correct these issues. Wpa_supplicant is built using madwifi-source and has been rebuilt using 0.9.3.1 source. _______________________________________________________________________ References: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-2829 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-2830 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-2831 _______________________________________________________________________ Updated Packages: Mandriva Linux 2007.0: 12348dbfba8628bfa7594209190591eb 2007.0/i586/madwifi-source-0.9.3.1-1.1mdv2007.0.noarch.rpm 69f23c96b9e5419bb9add4553b875cce 2007.0/i586/wpa_gui-0.5.5-2.2mdv2007.0.i586.rpm d09b5b0e4f5fdf4fc4db948dbffea169 2007.0/i586/wpa_supplicant-0.5.5-2.2mdv2007.0.i586.rpm cbcd53386bcfebff8d220b27059e6b69 2007.0/SRPMS/madwifi-source-0.9.3.1-1.1mdv2007.0.src.rpm 59139f14e119e5c205df03a02771f070 2007.0/SRPMS/wpa_supplicant-0.5.5-2.2mdv2007.0.src.rpm Mandriva Linux 2007.0/X86_64: 12348dbfba8628bfa7594209190591eb 2007.0/x86_64/madwifi-source-0.9.3.1-1.1mdv2007.0.noarch.rpm f17c658cae2dcfe6b3e97607584a2f2a 2007.0/x86_64/wpa_gui-0.5.5-2.2mdv2007.0.x86_64.rpm 71d9dc132a98d7113013e7a49459211d 2007.0/x86_64/wpa_supplicant-0.5.5-2.2mdv2007.0.x86_64.rpm cbcd53386bcfebff8d220b27059e6b69 2007.0/SRPMS/madwifi-source-0.9.3.1-1.1mdv2007.0.src.rpm 59139f14e119e5c205df03a02771f070 2007.0/SRPMS/wpa_supplicant-0.5.5-2.2mdv2007.0.src.rpm Mandriva Linux 2007.1: 1b51de79156fce38f5a8d1310632e2a4 2007.1/i586/madwifi-source-0.9.3.1-1.1mdv2007.1.noarch.rpm 32a18c21ab8217e4a076e9a2070b9c9b 2007.1/i586/wpa_gui-0.5.7-1.2mdv2007.1.i586.rpm b11c90cf4a982d3651cc5485198dd4d1 2007.1/i586/wpa_supplicant-0.5.7-1.2mdv2007.1.i586.rpm e7d7710a93440902d0ccd7b90ea6e939 2007.1/SRPMS/madwifi-source-0.9.3.1-1.1mdv2007.1.src.rpm 866afdd304a0bf415823a5db06b95066 2007.1/SRPMS/wpa_supplicant-0.5.7-1.2mdv2007.1.src.rpm Mandriva Linux 2007.1/X86_64: 1b51de79156fce38f5a8d1310632e2a4 2007.1/x86_64/madwifi-source-0.9.3.1-1.1mdv2007.1.noarch.rpm 4ad0a1957ce6d6cf9a3608f6d1dacb31 2007.1/x86_64/wpa_gui-0.5.7-1.2mdv2007.1.x86_64.rpm 04cb9776f30939ee111f4c6004da311a 2007.1/x86_64/wpa_supplicant-0.5.7-1.2mdv2007.1.x86_64.rpm e7d7710a93440902d0ccd7b90ea6e939 2007.1/SRPMS/madwifi-source-0.9.3.1-1.1mdv2007.1.src.rpm 866afdd304a0bf415823a5db06b95066 2007.1/SRPMS/wpa_supplicant-0.5.7-1.2mdv2007.1.src.rpm _______________________________________________________________________ To upgrade automatically use MandrivaUpdate or urpmi.
