A vulnerability has been identified in Opera, which could be exploited by attackers to execute arbitrary code. This issue is caused by an error when parsing a specially crafted BitTorrent header, which could be exploited by attackers to cause a vulnerable browser to use memory that has already been freed, resulting in an invalid object pointer being dereferenced when a user right clicks on the transfer and removes it.
