Updated samba packages that fix an input validation vulnerability are now available.. --------------------------------------------------------------------- Red Hat Security Advisory Synopsis: Updated samba packages fix security issue Advisory ID: RHSA-2004:498-01 Issue date: 2004-10-04 Updated on: 2004-10-04 Product: Red Hat Enterprise Linux CVE Names: CAN-2004-0815 --------------------------------------------------------------------- 1. Summary: Updated samba packages that fix an input validation vulnerability are now available. 2. Relevant releases/architectures: Red Hat Enterprise Linux AS (Advanced Server) version 2.1 - i386, ia64 Red Hat Linux Advanced Workstation 2.1 - ia64 Red Hat Enterprise Linux ES version 2.1 - i386 Red Hat Enterprise Linux WS version 2.1 - i386 3. Problem description: Samba provides file and printer sharing services to SMB/CIFS clients. Karol Wiesek discovered an input validation issue in Samba prior to 3.0.6. An authenticated user could send a carefully crafted request to the Samba server, which would allow access to files outside of the configured file share. Note: Such files would have to be readable by the account used for the connection. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-0815 to this issue. This issue does not affect Red Hat Enterprise Linux 3 as a previous erratum updated to Samba 3.0.6 which is not vulnerable to this issue. Users of Samba should upgrade to these updated packages, which contain an upgrade to Samba-2.2.12, which is not vulnerable to this issue. 4. Solution: Before applying this update, make sure that all previously-released errata relevant to your system have been applied. Use Red Hat Network to download and update your packages. To launch the Red Hat Update Agent, use the following command: up2date For information on how to install packages manually, refer to the following Web page for the SystemAdministration or Customization guide specific to your system: https://docs.redhat.com/en/documentation/red_hat_enterprise_linux/9/ 5.
