-----BEGIN PGP SIGNED MESSAGE----- ______________________________________________________________________________ SuSE Security Announcement Package: kdesu Announcement-ID: SuSE-SA:2001:02 Date: Affected SuSE versions: 6.0, 6.1, 6.2, 6.3, 6.4, 7.0 Vulnerability Type: local root compromise Severity (1-10): 3 SuSE default package: yes Other affected systems: All KDE 1 & KDE 2 systems Content of this advisory: 1) security vulnerability resolved: kdesu problem description, discussion, solution and upgrade information 2) pending vulnerabilities, solutions, workarounds 3) standard appendix (further information) ______________________________________________________________________________ 1) problem description, brief discussion, solution, upgrade information kdesu is a KDE frontend for su(1). When invoked it prompts for the root password and runs su(1). kdesu itself does not run setuid/setgid. However when enabling the 'keep password' option it tries to send the password across process boundaries to kdesud via a UNIX socket. During this it does not verify the identity of the listener on the other end. This allows attackers to obtain the root password. This bug has been fixed in the update packages by checking the ownership of the socket on the listener side. Download the update package from locations desribed below and install the package with the command `rpm -Uhv file.rpm'. The md5sum for each file is in the line below. You can verify the integrity of the rpm files using the command `rpm --checksig --nogpg file.rpm', independently from the md5 signatures below. i386 Intel Platform: SuSE-6.1: ftp://ftp.suse.com/pub/suse/i386/update/6.1/kpa1/kdesu-0.98-187.i386.rpm 3d51f84f2dc87916bc937f3afe507c1a SuSE-6.1: ftp://ftp.suse.com/pub/suse/i386/update/6.1/kpa1/kdesu.rpm 3d51f84f2dc87916bc937f3afe507c1a source rpm: ftp://ftp.suse.com/pub/suse/i386/update/6.1/zq1/kdesu-0.98-187.src.rpm f8764afd475fa7a41c18603d15ce48ab SuSE-6.2: ftp://ftp.suse.com/pub/suse/i386/update/6.2/kpa1/kdesu-0.98-187.i386.rpm 027617e19c957b1ed5f42f140b62521b SuSE-6.2: ftp://ftp.suse.com/pub/suse/i386/update/6.2/kpa1/kdesu.rpm 027617e19c957b1ed5f42f140b62521b source rpm: ftp://ftp.suse.com/pub/suse/i386/update/6.2/zq1/kdesu-0.98-187.src.rpm 9cf3d4b0c00db4598968dd5c7e07eef7 SuSE-6.3: ftp://ftp.suse.com/pub/suse/i386/update/6.3/kpa1/kdesu-0.98-187.i386.rpm d2b6c6f3330a20c2eb7d5500de2f9df6 SuSE-6.3: ftp://ftp.suse.com/pub/suse/i386/update/6.3/kpa1/kdesu.rpm d2b6c6f3330a20c2eb7d5500de2f9df6 source rpm: ftp://ftp.suse.com/pub/suse/i386/update/6.3/zq1/kdesu-0.98-187.src.rpm a50cc8ba1a793f9151559454fdad0a14 SuSE-6.4: ftp://ftp.suse.com/pub/suse/i386/update/6.4/kpa1/kdesu-0.98-187.i386.rpm 8f06dd49bdc00dca25eff33a3754ddee SuSE-6.4: ftp://ftp.suse.com/pub/suse/i386/update/6.4/kpa1/kdesu.rpm 8f06dd49bdc00dca25eff33a3754ddee source rpm: ftp://ftp.suse.com/pub/suse/i386/update/6.4/zq1/kdesu-0.98-187.src.rpm 0ca2d30cf51d1307f88581d4e240bbf0 SuSE-7.0: ftp://ftp.suse.com/pub/suse/i386/update/7.0/kpa1/kdesu-0.98-187.i386.rpm c7238ea5775939239b3857b550ca9f1b SuSE-7.0: ftp://ftp.suse.com/pub/suse/i386/update/7.0/kpa1/kdesu.rpm c7238ea5775939239b3857b550ca9f1b source rpm: ftp://ftp.suse.com/pub/suse/i386/update/7.0/zq1/kdesu-0.98-187.src.rpm bc74c75ba0b514f7df4f0250ccc7454a Sparc Platform: AXP Alpha Platform: SuSE-6.1: ftp://ftp.suse.com/pub/suse/axp/update/6.1/kpa1/kdesu-0.98-187.alpha.rpm 8017cd7fed463cae4bef3fa471e7e1d8 SuSE-6.1: ftp://ftp.suse.com/pub/suse/axp/update/6.1/kpa1/kdesu.rpm 8017cd7fed463cae4bef3fa471e7e1d8 source rpm: ftp://ftp.suse.com/pub/suse/axp/update/6.1/zq1/kdesu-0.98-187.src.rpm 78846e4ae3f50e9264e8840da1a628a8 SuSE-6.3: ftp://ftp.suse.com/pub/suse/axp/update/6.3/kpa1/kdesu-0.98-187.alpha.rpm cf1629ba236c0c84e0f2b33101b5f1aa SuSE-6.3: ftp://ftp.suse.com/pub/suse/axp/update/6.3/kpa1/kdesu.rpm cf1629ba236c0c84e0f2b33101b5f1aa source rpm: ftp://ftp.suse.com/pub/suse/axp/update/6.3/zq1/kdesu-0.98-187.src.rpm da851ebaee36cb91cb1e1fca0c8bfda2 SuSE-6.4: ftp://ftp.suse.com/pub/suse/axp/update/6.4/kpa1/kdesu-0.98-187.alpha.rpm d1904cc9db320ea2c576b73633ee6bd5 SuSE-6.4: ftp://ftp.suse.com/pub/suse/axp/update/6.4/kpa1/kdesu.rpm d1904cc9db320ea2c576b73633ee6bd5 source rpm: ftp://ftp.suse.com/pub/suse/axp/update/6.4/zq1/kdesu-0.98-187.src.rpm 27261cf8ff0ea66a597520260b832f7d SuSE-7.0: ftp://ftp.suse.com/pub/suse/axp/update/7.0/kpa1/kdesu-0.98-187.alpha.rpm be3b258eeeb3c56351b93ec8a32826db SuSE-7.0: ftp://ftp.suse.com/pub/suse/axp/update/7.0/kpa1/kdesu.rpm be3b258eeeb3c56351b93ec8a32826db source rpm: ftp://ftp.suse.com/pub/suse/axp/update/7.0/zq1/kdesu-0.98-187.src.rpm b7e3139377784c5cbbc4f14a5061d124 PPC Power PC Platform: SuSE-6.4: ftp://ftp.suse.com/pub/suse/ppc/update/6.4/kpa1/kdesu-0.98-187.ppc.rpm 705afa4defc64c48f89dd94b2d52c296 SuSE-6.4: ftp://ftp.suse.com/pub/suse/ppc/update/6.4/kpa1/kdesu.rpm 705afa4defc64c48f89dd94b2d52c296 source rpm: ftp://ftp.suse.com/pub/suse/ppc/update/6.4/zq1/kdesu-0.98-187.src.rpm 32e626fa7e8206d6803957c77062185b SuSE-7.0: ftp://ftp.suse.com/pub/suse/ppc/update/7.0/kpa1/kdesu-0.98-187.ppc.rpm e9b4a8a26844af0bc8cb37c8d2d26530 SuSE-7.0: ftp://ftp.suse.com/pub/suse/ppc/update/7.0/kpa1/kdesu.rpm e9b4a8a26844af0bc8cb37c8d2d26530 source rpm: ftp://ftp.suse.com/pub/suse/ppc/update/7.0/zq1/kdesu-0.98-187.src.rpm aaa092ffafe149ef8ba3acf570966e09 ______________________________________________________________________________ 2) Pending vulnerabilities in SuSE Distributions and Workarounds: - Kmail remote code execution.
