Re: Situation of samba packages (security update)



Quoting Adam D. Barratt (adam@adam-barratt.org.uk):

Thge diff will be the exact diff between two upstream versions.

So that means:

whatsnew.TXT is upstream "kinda changelog". It only lists the security
fix.

packaging/ is not used

Source3/VERSION is just changing the displayed version
ditto for source3/include/version.h

Source3/* is upstream's fix

source4/ldap_server/devdocs/AD-Syntaxes.txt...hmm, is noise, but
doesn't harm and isn't used

Full diff attached.

                    =============================
+                   Release Notes for Samba 3.4.9
+			 September 14, 2010
+                   =============================
+
+
+This is a security release in order to address CVE-2010-3069.
+
+
+o  CVE-2010-3069:
+   All current released versions of Samba are vulnerable to
+   a buffer overrun vulnerability. The sid_parse() function
+   (and related dom_sid_parse() function in the source4 code)
+   do not correctly check their input lengths when reading a
+   binary representation of a Windows SID (Security ID). This
+   allows a malicious client to send a sid that can overflow
+   the stack variable that is being used to store the SID in the
+   Samba smbd server.
+
+
+Changes since 3.4.8
+-------------------
+
+
+o   Jeremy Allison <jra@samba.org>
+    * BUG 7669: Fix for CVE-2010-3069.
+
+
+o   Andrew Bartlett <abartlet@samba.org>
+    * BUG 7669: Fix for CVE-2010-3069.
