Description Tim Sammut (RETIRED) gentoo-dev 2010-09-14 15:49:14 UTC
From $URL:

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.

Thanks, Patrick. Are there any issues with stabilizing 3.5.5 with only 3.4.8 stable now?

Comment 3 Alex Legler (RETIRED) archtester gentoo-dev Security 2010-09-14 17:12:08 UTC
3.4.9 was released as an update for the 3.4 slot as well:

It should be the preferred stabilization target.

I'd prefer 3.5, but I just added 3.4.9 so you can have fun with it.

  Stack-based buffer overflow in the (1) sid_parse and (2) dom_sid_parse
  functions in Samba before 3.5.5 allows remote attackers to cause a denial of
  service (crash) and possibly execute arbitrary code via a crafted Windows
  Security ID (SID) on a file share.
