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)
