    Solution Type: Sun Alert
    Solution  237987 :   Manipulated Tag Files used with Solaris Text
    Editors May Lead to Execution of Arbitrary Code
    Bug ID: 6510560

    Product
    Solaris 8 Operating System
    Solaris 9 Operating System
    Solaris 10 Operating System

    Date of Resolved Release: 17-Sep-2008

    SA Document Body
    Manipulated Tag Files used with Solaris Text Editors May Lead to
    Execution of Arbitrary Code

    1. Impact
    A security vulnerability in the Solaris text editors (vi(1), ex(1),
    vedit(1), view(1), edit(1)), related to the handling of tags (see
    ctags(1)) may allow a local unprivileged user to execute arbitrary
    code with the privileges of another user.
    Sun acknowledges with thanks, "Eli the Bearded" for bringing this
    issue to our attention.

    2. Contributing Factors
    This issue can occur in the following releases:
    SPARC Platform:
      * Solaris 8 without patch 110903-08
      * Solaris 9 without patch 113031-04
      * Solaris 10 without patch 120830-06

    x86 Platform:
      * Solaris 8 without patch 110904-08
      * Solaris 9 without patch 116479-02
      * Solaris 10 without patch 120831-06

    3. Symptoms
    There are no reliable symptoms that would indicate the described issue
    has occurred.

    4. Workaround
    To avoid this issue, do not use the '-t' option or the ':tag' command
    with the Solaris text editors (vi, ex, vedit, view or edit). Use the
    ctags(1) utility to recreate the tags file.

    5. Resolution

    This issue is addressed in the following releases:
    SPARC Platform
      * Solaris 8 with patch 110903-08 or later
      * Solaris 9 with patch 113031-04 or later
      * Solaris 10 with patch 120830-06 or later

    x86 Platform
      * Solaris 8 with patch 110904-08 or later
