From security@mandriva.com Tue Dec 20 21:04:07 2005 From: Mandriva Security Team To: full-disclosure@lists.grok.org.uk Date: Tue, 20 Dec 2005 13:31:01 -0700 Subject: [Full-disclosure] MDKSA-2005:234 - Updated sudo packages fix vulnerability -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 _______________________________________________________________________ Mandriva Linux Security Advisory MDKSA-2005:234 http://www.mandriva.com/security/ _______________________________________________________________________ Package : sudo Date : December 20, 2005 Affected: 10.1, 10.2, 2006.0, Corporate 2.1, Corporate 3.0, Multi Network Firewall 2.0 _______________________________________________________________________ Problem Description: Charles Morris discovered a vulnerability in sudo versions prior to 1.6.8p12 where, when the perl taint flag is off, sudo does not clear the PERLLIB, PERL5LIB, and PERL5OPT environment variables, which could allow limited local users to cause a perl script to include and execute arbitrary library files that have the same name as library files that included by the script. In addition, other environment variables have been included in the patch that remove similar environment variables that could be used in python and ruby, scripts, among others. The updated packages have been patched to correct this problem. _______________________________________________________________________ References: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2005-4158 http://www.sudo.ws/sudo/alerts/perl_env.html _______________________________________________________________________ Updated Packages: Mandriva Linux 10.1: 2516e27be7da2de14cccef0a77adf35a 10.1/RPMS/sudo-1.6.8p1-1.4.101mdk.i586.rpm 3c6e47db109ab754ecfd50037a163fe4 10.1/SRPMS/sudo-1.6.8p1-1.4.101mdk.src.rpm Mandriva Linux 10.1/X86_64: ba79d9f091d06ce3654584e97d6ea695 x86_64/10.1/RPMS/sudo-1.6.8p1-1.4.101mdk.x86_64.rpm 3c6e47db109ab754ecfd50037a163fe4 x86_64/10.1/SRPMS/sudo-1.6.8p1-1.4.101mdk.src.rpm Mandriva Linux 10.2: 8481507149ed3e20e2cb1ee2ac1aac2d 10.2/RPMS/sudo-1.6.8p1-2.3.102mdk.i586.rpm 34401e963a063bd36d580b188fc7d5f4 10.2/SRPMS/sudo-1.6.8p1-2.3.102mdk.src.rpm Mandriva Linux 10.2/X86_64: d105ea0dcf161229cf18bd0b4ad49ae4 x86_64/10.2/RPMS/sudo-1.6.8p1-2.3.102mdk.x86_64.rpm 34401e963a063bd36d580b188fc7d5f4 x86_64/10.2/SRPMS/sudo-1.6.8p1-2.3.102mdk.src.rpm Mandriva Linux 2006.0: da9c44f3f29809e72f0b3eac2ad08237 2006.0/RPMS/sudo-1.6.8p8-2.2.20060mdk.i586.rpm 218a529af57212352cb76bb6dddff6f7 2006.0/SRPMS/sudo-1.6.8p8-2.2.20060mdk.src.rpm Mandriva Linux 2006.0/X86_64: 497b26c02a39f889436af1233a3ccf17 x86_64/2006.0/RPMS/sudo-1.6.8p8-2.2.20060mdk.x86_64.rpm 218a529af57212352cb76bb6dddff6f7 x86_64/2006.0/SRPMS/sudo-1.6.8p8-2.2.20060mdk.src.rpm Corporate Server 2.1: a2ff055e40e82badb298e5e43616fa7a corporate/2.1/RPMS/sudo-1.6.6-2.4.C21mdk.i586.rpm 757021ec14b8d6bbf5092a55717fed8e corporate/2.1/SRPMS/sudo-1.6.6-2.4.C21mdk.src.rpm Corporate Server 2.1/X86_64: d8726687c4576fa798d9689a7ca1783f x86_64/corporate/2.1/RPMS/sudo-1.6.6-2.4.C21mdk.x86_64.rpm 757021ec14b8d6bbf5092a55717fed8e x86_64/corporate/2.1/SRPMS/sudo-1.6.6-2.4.C21mdk.src.rpm Corporate 3.0: 3f8e7d74cf2a9a1df4558aae11596186 corporate/3.0/RPMS/sudo-1.6.7-0.p5.2.4.C30mdk.i586.rpm 9b06900a06ba7f5185c4d975d6cf5600 corporate/3.0/SRPMS/sudo-1.6.7-0.p5.2.4.C30mdk.src.rpm Corporate 3.0/X86_64: c5b266372ba22c8899e35051e844ddca x86_64/corporate/3.0/RPMS/sudo-1.6.7-0.p5.2.4.C30mdk.x86_64.rpm 9b06900a06ba7f5185c4d975d6cf5600 x86_64/corporate/3.0/SRPMS/sudo-1.6.7-0.p5.2.4.C30mdk.src.rpm Multi Network Firewall 2.0: 13b9e27dd7f1811edce5bba617699ddc mnf/2.0/RPMS/sudo-1.6.7-0.p5.2.4.M20mdk.i586.rpm 65e7086a169fbf3200220e347d6824aa mnf/2.0/SRPMS/sudo-1.6.7-0.p5.2.4.M20mdk.src.rpm _______________________________________________________________________ To upgrade automatically use MandrivaUpdate or urpmi.
