[RHSA-1999:022-03] New Samba pacakges available (updated)
--------------------------------------------------------------------- Red Hat, Inc. Security Advisory Synopsis: New samba packages for Red Hat Linux 4.2, 5.2, 6.0 Advisory ID: RHSA-1999:022-02 Issue date: 1999-07-22 Updated on: 1999-07-29 Keywords: samba smbd nmbd security Cross references: --------------------------------------------------------------------- Revision History: 1999-07-23: Fix 'Conflicts with' section about smbmount with 2.0/2.2 kernels. 1999-07-29: Add note about %postun of Red Hat Linux 6.0 samba release. 1. Topic: Samba 2.0.5a has been released. Among the fixes in this release are several security issues present in previous Samba releases. 2. Bug IDs fixed: 1321 2557 2625 2779 2923 2982 3715 3. Relevant releases/architectures: Red Hat Linux 6.0, all architectures Red Hat Linux 5.2, all architectures Red Hat Linux 4.2, all architectures 4. Obsoleted by: 5. Conflicts with: The smbmount code shipped with Samba 2.0 is only compatible with the Linux 2.2 kernel, so it has not been built for the Red Hat Linux 4.2 and 5.2 releases. If smbmount support for the 2.2 kernel is needed under Red Hat Linux 4.2 or 5.2, the source RPM can be rebuilt with the following command line (RPM version 3.0 is required): rpm --define "KERN22 yes" --rebuild samba-2.0.5a-<release>.src.rpm The samba package shipped with Red Hat Linux 6.0 (samba-2.0.3-8) has an erroneous post-uninstall script. If this package is upgraded to the errata release, it could cause /var/log/samba and /var/lock/samba to be missing. It is recommended that users of samba under Red Hat Linux 6.0 uninstall the previous release using 'rpm -e samba' before installing the errata release. 6. RPMs required: Red Hat Linux 6.0: Intel: ftp://updates.redhat.com/6.0/i386/ samba-2.0.5a-1.i386.rpm samba-client-2.0.5a-1.i386.rpm Alpha: ftp://updates.redhat.com/6.0/alpha/ samba-2.0.5a-1.alpha.rpm samba-client-2.0.5a-1.alpha.rpm Sparc: ftp://updates.redhat.com/6.0/sparc/ samba-2.0.5a-1.sparc.rpm samba-client-2.0.5a-1.sparc.rpm Source: ftp://updates.redhat.com/6.0/ samba-2.0.5a-1.src.rpm Red Hat Linux 5.2: Intel: ftp://updates.redhat.com/5.2/i386/ samba-2.0.5a-0.5.2.i386.rpm samba-client-2.0.5a-0.5.2.i386.rpm Alpha: ftp://updates.redhat.com/5.2/alpha/ samba-2.0.5a-0.5.2.alpha.rpm samba-client-2.0.5a-0.5.2.alpha.rpm Sparc: ftp://updates.redhat.com/5.2/sparc/ samba-2.0.5a-0.5.2.sparc.rpm samba-client-2.0.5a-0.5.2.sparc.rpm Source: ftp://updates.redhat.com/5.2/ samba-2.0.5a-0.5.2.src.rpm Red Hat Linux 4.2: Intel: ftp://updates.redhat.com/4.2/i386/ samba-2.0.5a-0.4.2.i386.rpm samba-client-2.0.5a-0.4.2.i386.rpm Alpha: ftp://updates.redhat.com/4.2/alpha/ samba-2.0.5a-0.4.2.alpha.rpm samba-client-2.0.5a-0.4.2.alpha.rpm Sparc: ftp://updates.redhat.com/4.2/sparc/ samba-2.0.5a-0.4.2.sparc.rpm samba-client-2.0.5a-0.4.2.sparc.rpm Source: ftp://updates.redhat.com/4.2/ samba-2.0.5a-0.4.2.src.rpm 7. Problem description: Several security issues were present in earlier samba releases. - a denial-of-service attack could be performed against nmbd. - a buffer overflow was present in the message service in smbd (not enabled by default under Red Hat Linux) - a race condition was present in smbmnt that could cause problems if installed setuid root (it is not installed setuid root by default under Red Hat Linux 6.0, and is not present under Red Hat Linux 4.2 or 5.2) Thanks go to Olaf Kirch (okir@caldera.de) for discovering the security holes, as well as the Samba team. 8. Solution: Install the updated RPMs, and restart the affected services by running: /etc/rc.d/init.d/smb restart For each RPM for your particular architecture, run: rpm -Uvh <filename> where filename is the name of the RPM. 9. Verification: MD5 sum Package Name -------------------------------------------------------------------------- 5167d97fb2f0949991555a3b8e86d509 samba-2.0.5a-1.i386.rpm 969d609925bc09f9c113907124828dc6 samba-client-2.0.5a-1.i386.rpm d8091f3fa0aeda8febf3553d5b92f53f samba-2.0.5a-1.alpha.rpm 99f334ef87347877d1b79d4801044547 samba-client-2.0.5a-1.alpha.rpm 58b1afe4c81028435e6cad1325d4bbee samba-2.0.5a-1.sparc.rpm 6e3939fcebba7ace639b766b1cf36cab samba-client-2.0.5a-1.sparc.rpm 5c87d78148a8a224e5f89e5dce9af1ae samba-2.0.5a-1.src.rpm 6ce227464edc1e79cf4433ede6d18c05 samba-2.0.5a-0.5.2.i386.rpm 0f8d4c9606af2fd809c55a6dd3f9beae samba-client-2.0.5a-0.5.2.i386.rpm cb51e889747ed1786996323863f64868 samba-2.0.5a-0.5.2.alpha.rpm f82cfb4807fa9399005a03d6dd65dca5 samba-client-2.0.5a-0.5.2.alpha.rpm d56551d53be6928556bb58517f265e9f samba-2.0.5a-0.5.2.sparc.rpm 371f7de9553d9c86c4b62d2a92c84bf0 samba-client-2.0.5a-0.5.2.sparc.rpm e411e3c19d19ab89d35e834c7d379589 samba-2.0.5a-0.5.2.src.rpm c5d267fc6b47a84f0571f0ce1a7a15aa samba-2.0.5a-0.4.2.i386.rpm 3d07e39245cdc5d8aa0ba8d50e6178f1 samba-client-2.0.5a-0.4.2.i386.rpm f3db3e6f607afbd861610570154fd19d samba-2.0.5a-0.4.2.alpha.rpm 7972cf576734d1b006258a8ca02c80ff samba-client-2.0.5a-0.4.2.alpha.rpm c44a4c13f171f31686d91da3b8370311 samba-2.0.5a-0.4.2.sparc.rpm a6c235a206349e347dfe35ac0064d901 samba-client-2.0.5a-0.4.2.sparc.rpm 0c326cb2a2b0964026d286fb5f6b8079 samba-2.0.5a-0.4.2.src.rpm These packages are PGP signed by Red Hat Inc. for security.
