Debian: New xwine packages fix several vulnerabilities
 by Patrick Lenz, in Security - Mon, Mar 24th 2008 07:54 PDT

Steve Kemp from the Debian Security Audit project discovered several local vulnerabilities have been discovered in xwine, a graphical user interface for the WINE emulator. The xwine command makes unsafe use of local temporary files when printing. This could allow the removal of arbitrary files belonging to users who invoke the program. The xwine command changes the permissions of the global WINE configuration file such that it is world-writable. This could allow local users to edit it such that arbitrary commands could be executed whenever any local user executed a program under WINE. Fixed packages are available from security.debian.org.

Package        : xwine

Problem type   : local
Debian-specific: no
CVE Id(s)      : CVE-2008-0930 CVE-2008-0931

Steve Kemp from the Debian Security Audit project discovered several local
vulnerabilities have been discovered in xwine, a graphical user interface
for the WINE emulator.

The Common Vulnerabilities and Exposures project identifies the following
problems:

CVE-2008-0930
 The xwine command makes unsafe use of local temporary files when
 printing.  This could allow the removal of arbitrary files belonging
 to users who invoke the program.

CVE-2008-0931
 The xwine command changes the permissions of the global WINE configuration
 file such that it is world-writable.  This could allow local users to edit
 it such that arbitrary commands could be executed whenever any local user
 executed a program under WINE.

For the stable distribution (etch), these problems have been fixed in version
1.0.1-1etch1.

We recommend that you upgrade your xwine package.
