Debian Security Advisory

DSA-1526-1 xwine -- various

Date Reported:

20 Mar 2008

Affected Packages:

xwine

Vulnerable:

Yes

Security database references:

In Mitre's CVE dictionary: CVE-2008-0930, CVE-2008-0931.

More information:

Steve Kemp from the Debian Security Audit project discovered several local vulnerabilities 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 arbitary 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.

Fixed in:

Debian GNU/Linux 4.0 (etch)
