      CVS Undocumented Flag Information Disclosure Vulnerability (history.c)
    ------------------------------------------------------------------------

    SUMMARY

    CVS (Concurrent Versions System) is "an open-source network-transparent
    version control system".

    Remote exploitation of an information disclosure vulnerability in
    Concurrent Versions Systems (CVS) allows attackers to glean information.

    DETAILS

    Vulnerable Systems:
     * CVS version 1.11 and prior

    Immune Systems:
     * CV version 1.11.17, version 1.12.9, or newer

    The vulnerability exists within an undocumented switch to the 'history'
    command implemented in src/history.c. The -X command specifies the name of
    the history file allowing an attacker to determine whether arbitrary
    system files and directories exist and whether or not the CVS process has
    access to them.

    Analysis:
    Successful exploitation allows remote attackers with credentials to the
    affected CVS server to determine whether or not arbitrary system files and
    directories exist and are accessible under the permissions of the user
    that the CVS daemon runs under.
