Version(s): 1.7.3
Description:   A heap overflow vulnerability was reported in Mozilla in the processing of NNTP URLs. A remote user can execute arbitrary code on the target system.

Maurycy Prodeus of iSEC Security Research reported that a remote user can create a specially crafted 'news://' URL that, when loaded by the target user, will trigger a buffer overflow and execute arbitrary code on the target user's system. The code will run with the privileges of the target user.

The flaw resides in the *MSG_UnEscapeSearchUrl() function in 'nsNNTPProtocol.cpp'.
