From security@linux-mandrake.com Fri Feb 14 15:46:03 2003 From: Mandrake Linux Security Team To: bugtraq@securityfocus.com Date: 14 Feb 2003 00:53:51 -0000 Subject: MDKSA-2003:016 - Updated util-linux packages provide stronger randomness in mcookie -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ________________________________________________________________________ Mandrake Linux Security Update Advisory ________________________________________________________________________ Package name: util-linux Advisory ID: MDKSA-2003:016 Date: February 13th, 2003 Affected versions: 8.2, 9.0 ________________________________________________________________________ Problem Description: The util-linux package provides the mcookie utility, a tool for generating random cookies that can be used for X authentication. The util-linux packages that were distributed with Mandrake Linux 8.2 and 9.0 had a patch that made it use /dev/urandom instead of /dev/random, which resulted in the mcookie being more predictable than it would otherwise be. This patch has been removed in these updates, giving mcookie a better source of entropy and making the generated cookies less predictable. Thanks to Dirk Mueller for pointing this out. ________________________________________________________________________ References: ________________________________________________________________________ Updated Packages: Mandrake Linux 8.2: 42ff78fc528a12c85074b9930e5dca40 8.2/RPMS/losetup-2.11n-4.4mdk.i586.rpm 95d6fa4f6657799dc47eaeb5cb77cafc 8.2/RPMS/mount-2.11n-4.4mdk.i586.rpm 1a0cd7a36dc16fc6229812669d2bfc87 8.2/RPMS/util-linux-2.11n-4.4mdk.i586.rpm 6bf632bf623ec261d96b63fb267bd4e9 8.2/SRPMS/util-linux-2.11n-4.4mdk.src.rpm Mandrake Linux 8.2/PPC: a63c201ccb44b3db876e8b730644a449 ppc/8.2/RPMS/losetup-2.11n-4.4mdk.ppc.rpm 59bce5df786546785a8425006749d0f0 ppc/8.2/RPMS/mount-2.11n-4.4mdk.ppc.rpm 27591222bc4498183f48fa11f1edbbf3 ppc/8.2/RPMS/util-linux-2.11n-4.4mdk.ppc.rpm 6bf632bf623ec261d96b63fb267bd4e9 ppc/8.2/SRPMS/util-linux-2.11n-4.4mdk.src.rpm Mandrake Linux 9.0: 09586a3e81b2212b8044445fc4559fc5 9.0/RPMS/losetup-2.11u-1.1mdk.i586.rpm be9751b84f20ec4bc1ced03c4004dcb4 9.0/RPMS/mount-2.11u-1.1mdk.i586.rpm 613661ae3c324580e653330814f74756 9.0/RPMS/util-linux-2.11u-1.1mdk.i586.rpm 757145e95a3a990f0c95589cd0324a71 9.0/SRPMS/util-linux-2.11u-1.1mdk.src.rpm ________________________________________________________________________ Bug IDs fixed (see https://qa.mandrakesoft.com for more information): ________________________________________________________________________ To upgrade automatically, use MandrakeUpdate.
