Steve Kemp from the Debian Security Audit project discovered that gforge, a collaborative development tool, used temporary files insecurely which could allow local users to truncate files upon the system with the privileges of the gforge user, or create a denial of service attack.
For the old stable distribution (sarge), this problem has been fixed in version 3.1-31sarge4.
For the stable distribution (etch), this problem has been fixed in version 4.5.14-22etch3.
We recommend that you upgrade your gforge package.
MD5 checksums of the listed files are available in the original advisory.
