Secunia reports:

Some vulnerabilities have been reported in DokuWiki, which can be exploited by malicious people to cause a DoS (Denial of Service) or potentially compromise a vulnerable system.

Input passed to the "w" and "h" parameters in lib/exec/fetch.php is not properly sanitised before being passed as resize parameters to the "convert" application. This can be exploited to cause a DoS due to excessive CPU and memory consumption by passing very large numbers, or to inject arbitrary shell commands by passing specially crafted strings to the "w" and "h" parameter.

Successful exploitation requires that the "$conf[imconvert]" option is set.
