IRIX 6.2/6.3/6.4 xfs truncate() Privilege Check Vulnerability (EDBID:20137)

The truncate() system call on a number of versions of the IRIX operating system (with the xfs file system) does not properly check permissions before truncating a file, making it possible for unprivileged users to damage files to which they would otherwise not have write access. Although only versions 6.2, 6.3, and 6.4 are listed as vulnerable other versions may exhibit this behaviour as well.

/*   truncates any file on a xfs filesystem                                   */
