Comix 3.6.4 creates temporary directories with predictable names, which allows local users to cause an unspecified denial of service.

The remote host is affected by the vulnerability described in GLSA-200804-29 (Comix: Multiple vulnerabilities)

    Comix does not properly sanitize filenames containing shell     metacharacters when they are passed to the rar, unrar, or jpegtran     programs (CVE-2008-1568). Comix also creates directories with     predictable names (CVE-2008-1796).
  Impact :

    A remote attacker could exploit the first vulnerability by enticing a     user to use Comix to open a file with a specially crafted filename,     resulting in the execution of arbitrary commands. The second     vulnerability could be exploited by a local attacker to cause a Denial     of Service by creating a file or directory with the same filename as     the predictable filename used by Comix.
  Workaround :

    There is no known workaround at this time.

Several security flaws are reported against comix 3.6.4. One issue is that comix uses os.popen() to execute external commands without handling filenames properly. This may allow malicios users to execute arbitrary commands by opening some files with crafted names. This issue is now identified as CVE-2008-1568. Another issue is that comix creates a directory under /tmp with the name easily predictable by any users. This will cause DOS attach for multiuser system. This new package will fix these issues.
