Qpopper 4.0.3 is available at
<ftp://ftp.qualcomm.com/eudora/servers/unix/popper/>.


**** 4.0.3 FIXES A BUFFER OVERFLOW PRESENT IN ALL VERSIONS OF 4.0 --
PLEASE UPGRADE IMMEDIATELY ***

We hope that this information is accurate. Version 4.0.2 is not on the ftp
server any more, and there is no patch from 4.0.2 to 4.0.3.
We currently feel handicapped in our efforts to check the code for the
changes wrt the buffer overflow.

SuSE ships qpopper versions 2.53 (with a set of patches that include
security fixes for this version) for SuSE-6.3, 6.4 and 7.0, SuSE-7.1 and
the upcoming SuSE-7.2 release have version 3.1.2.

If the above statement is right, then SuSE distributions are not
vulnerable. However, we wish to double-check such a claim. All kinds of
verification and transparency are welcome, including an official statement
from Qualcomm (thanks in advance!).


Changes from 4.0.2 to 4.0.3:
----------------------------
  1.  Don't call SSL_shutdown unless we tried to negotiate an
      SSL session.  (As suggested by Kenneth Porter.)
  2.  Fix buffer overflow  (reported by Gustavo Viscaino).


Thank you,
Roman Drahtmüller,
SuSE Security.
