descriptionA buffer overflow vulnerability has been detected in the greed URL handling code. This bug can especially be a problem when greed is used to process GRX (GetRight) files that originate from untrusted sources. The bug finder, Manigandan Radhakrishnan, gave the following description : Here are the bugs. First, in main.c, DownloadLoop() uses strcat() to copy an input filename to the end of a 128-byte COMMAND array. Second, DownloadLoop() passes the input filename to system() without checking for special characters such as semicolons.
