Customer Support - RealOne Security Updates
Updated January 25, 2002
On January 17th, 2002, a security exploit affecting RealPlayer 8 was brought to the attention of RealNetworks. The specific exploit, commonly known as a "buffer overrun", could allow an attacker to run arbitrary code on a user's machine.
We have not yet received reports of anyone actually being attacked with this exploit. However, RealNetworks, has found and fixed the problem.
The bug is essentially a parsing error in the player code associated with reading RM files, commonly known as a "buffer overrun" bug which could theoretically be used by hackers to adversely affect users. The bug was fixed by improving the robustness of file parsing. When RealPlayer encounters files modified in the manner described by this exploit, it will now inform the user that the file is corrupt when played.
The following versions of the RealOne Player and RealPlayer are affected:
- RealOne Player
- RealPlayer 8
- RealPlayer 7
- RealPlayer G2 (Build # 18.104.22.168 or higher)
- RealPlayer Intranet 8
- RealPlayer Intranet 7
- RealPlayer 8
- RealPlayer 7
- RealOne Player Alpha for Linux 2.2
- RealPlayer 8 for UNIX
- RealPlayer 7 for UNIX
We have not yet received reports of anyone actually being attacked with this exploit. To ensure that your RealPlayer is protected, we recommend installing the updates available.
