Please respond ASAP. The issue is public. Factory only sufficient ------------------------------------------------------------------------------ Date: Sun, 18 Apr 2010 18:58:30 +0200 From: "Matthias Andree" <matthias.andree(a)gmx.de> Subject: [oss-security] CVE request: fetchmail 4.6.3...6.3.16 DoS in -v -v mode in multibyte locales on invalid input Please assign a CVE id for the issue described below. (Best viewed in non-proportional font with 8 space tabs): Draft announcement: - DRAFT - XXX - DRAFT - fetchmail-SA-2010-02: Denial of service in debug mode w/ multichar locales Topics: Denial of service in debug output. Author: Matthias Andree Version: 0.1 XXX Announced: XXX Type: malloc() Buffer overrun with printable characters Impact: Denial of service. Danger: low CVE Name: CVE-2010-XXXX CVSSv2: XXX URL: http://www.fetchmail.info/fetchmail-SA-2010-02.txt Project URL: http://www.fetchmail.info/ Affects: fetchmail releases 4.6.3 up to and including 6.3.16 Not affected: fetchmail release 6.3.17 and newer Corrected: 2010-04-18 Git (XXX) 0. Release history ================== 2010-04-18 0.1 first draft (visible in SVN and through oss-security) XXX 1. Background ============= fetchmail is a software package to retrieve mail from remote POP2, POP3, IMAP, ETRN or ODMR servers and forward it to local SMTP, LMTP servers or message delivery agents. It supports SSL and TLS security layers through the OpenSSL library, if enabled at compile time and if also enabled at run time. 2. Problem description and Impact ================================= In debug mode (-v -v), fetchmail prints information that was obtained from the upstream server (POP3 UIDL lists) or from message headers retrieved from it. If printing such information fails, for instance because there are invalid multibyte character sequences in this information (message headers), fetchmail will misinterpret this condition, and believe that the buffer was too small, and reallocate a bigger one (with linearly increasing buffer size), and repeat, until the allocation fails. At that point, fetchmail will abort. Note that the "Affects:" line above may be inaccurate, and it may be that versions before 5.6.6 are actually unaffected. The author was unable to compile such old fetchmail versions to verify the existence of the bug. Given that other security issues are present in such versions, those should not be used, and the wider version range was listed as vulnerable to err towards the safe. 3. Solution =========== There are two alternatives, either of them by itself is sufficient: a. Apply the patch found in section B of this announcement to fetchmail 6.3.14 or newer, recompile and reinstall it. b. Install fetchmail 6.3.17 or newer after it will have become available. The fetchmail source code is always available from <http://developer.berlios.de/project/showfiles.php?group_id=1824>. 4. Workaround ============= Run fetchmail with at most one -v (--verbose) option.

I followed this Wiki page to the letter: http://en.opensuse.org/Openssh#SFTP_chroot_with_ChrootDirectory I have Swedish community users trying to set this up to with same result as me. This thread takes up the same issue: http://marc.info/?l=openssh-unix-dev&m=122640731518850&w=2 But the solution mentioned there is not acceptable because as it stats on the Wiki you make one folder the chroot folder and then mapping the users home folder relative to the chroot folder, in this scenario the users should get write permissions to his own folder, but that is not possible, thus breaking the functionality intended. So the question is, is this a bug or is it designed to act like this? Reproducible: Always Steps to Reproduce: Done accordingly to this wiki entry: http://en.opensuse.org/OpenSSH Actual Results: Gets a read only home folder root Expected Results: Getting a writable home folder, where they can create on folder and upload files directly to the root of their home folder. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

There are other intervals where similar problems arise, like [42.0:42.2] where the scale is [40:50]. The --alt-autoscale improves the scaling, but has a problem with not enough numeric labels for the y-axis being shown, just as --rigid does. The author of the tool said the current version is much better regarding those issues. Reproducible: Sometimes Steps to Reproduce: 1. Create graphs with automatic scaling where the values vary a little bit around some undetermined value Actual Results: Some graphs are not good enough to show the variations.
