Description:
iDEFENSE reported an information disclosure vulnerability in CVS. A remote authenticated user can determine if certain specified files and directories exist.
It is reported that there is an undocumented switch in the 'history' command in 'src/history.c'. A remote authenticated user can supply an arbitrary filename to the '-X' command switch (used to specify the history file) and then analyze the resulting error messages to determine if the named file exists on the target system and if the CVS process has access to the file.
The vendor was reportedly notified on July 22, 2004. [Editor's note: This notification date is after the date of the vendor fix (June 9, 2004).
The original advisory is available at:

|
Impact:
A remote authenticated user can determine if files or directories exist on the target system. The user can also determine if the CVS daemon has access to the files or directories.

Solution:
Mandrake has issued a fix.

Mandrakelinux Security Update Advisory
_______________________________________________________________________
Package name: cvs
Advisory ID: MDKSA-2004:108
Date: October 19th, 2004
Affected versions: 10.0, 9.2, Corporate Server 2.1
______________________________________________________________________
Problem Description:
iDEFENSE discovered a flaw in CVS versions prior to 1.1.17 in an
undocumented switch implemented in CVS' history command. The -X
switch specifies the name of the history file which allows an attacker
to determine whether arbitrary system files and directories exist and
whether or not the CVS process has access to them.
This flaw has been fixed in CVS version 1.1.17.
