=========================================================================== SCO Security Bulletin 98.06 October 6, 1998 Security Vulnerability in imapd --------------------------------------------------------------------------- I. Description A security vulnerability which was previously addressed for SCO UnixWare 7 has been discovered to apply also to SCO OpenServer Release 5.0.5. (Note that previous releases of OpenServer are not affected). The vulnerability is described in CERT advisory CA-98.09. II. Impact The vulnerability could allow remote attackers to gain root access. Exploit details for the vulnerability have been published, so we recommend that the patch described below be installed on all Internet-connected systems as soon as possible. III. Releases This problem exists on the following releases of SCO operating systems: - SCO OpenServer Release 5.0.5 only - SCO UnixWare 7 Other SCO products are not affected (imapd is not included in previous releases of OpenServer). IV. Solution SCO is providing an interim patch to address this issue in the form of a System Security Enhancement (SSE) package. SSE014b contains replacement imapd binaries for each system type. Note that the UnixWare 7 binary was previously included in SSE014 - if you have already installed SSE014 on UnixWare 7, it is not necessary to install SSE014b. SSE014b is available for Internet download via anonymous ftp, and from the SCOFORUM on Compuserve. You can download the SSE package as follows: Anonymous ftp (World Wide Web URL): ftp://ftp.sco.COM/SSE/sse014b.ltr (cover letter, ASCII text) ftp://ftp.sco.COM/SSE/sse014b.tar.Z (new binaries, compressed tar file) Compuserve: GO SCOFORUM, and search Library 11 (SLS/SSE Files) for these filenames: SSE014B.LTR (cover letter, ASCII text) SSE014B.TAZ (new binaries, compressed tar file) Checksums (sum -r): 38104 5 sse014b.ltr 31525 658 sse014b.tar.Z V.
