HARDWARE PLATFORM(S)      : /

OPERATING SYSTEM(S)       : Solaris 9, Solaris 10 running scp.

Sun(sm) Alert Notification
      * Sun Alert ID: 102961
      * Synopsis: Security Vulnerability in scp(1) May Allow Execution of
        Unintended Commands
      * Category: Security
      * Product: Solaris 9 Operating System, Solaris 10 Operating System
      * BugIDs: 6472377
      * Avoidance: Patch, Workaround
      * State: Workaround
      * Date Released: 08-Jun-2007
      * Date Closed:
      * Date Modified: 21-Jun-2007, 26-Jun-2007

1. Impact

    Due to a security vulnerability in the way the scp(1) command executes
    helper applications, certain additional unintended commands may be
    executed at the same time. This may allow a local unprivileged user
    (or a remote user in the case of shared filesystems) who is able to
    create files on the system, to execute arbitrary commands with the
    privileges of a local user, if those files are acted upon by the local
    user using the scp(1) command.

    This issue is also referenced in the following document:

    CVE-2006-0225
    at http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-0225

2. Contributing Factors

    This issue can occur in the following releases:

    SPARC Platform
      * Solaris 9
      * Solaris 10 without patch 123324-03

    x86 Platform
      * Solaris 9
      * Solaris 10 without patch 123325-03

    Note: Solaris 8 does not include the scp(1) command and is therefore
    not impacted by this issue.

3. Symptoms

    There are no predictable symptoms that would indicate that this issue
    has been exploited to execute arbitrary commands.

4. Relief/Workaround

    This issue will only occur if the scp(1) command is executed on files
    that have specially crafted filenames. Therefore, it may be possible
    to work around this issue by avoiding the use of the scp(1) command on
    untrusted filenames, for example, on directories that are writable by
    untrusted users.

5. Resolution

    This issue is addressed in the following releases:

    SPARC Platform
      * Solaris 10 with patch 123324-03 or later

    x86 Platform
      * Solaris 10 with patch 123325-03 or later

    A final resolution is pending completion.
