Diego Juarez has reported a vulnerability in Orbit Downloader, which potentially can be exploited by malicious people to compromise a user's system.
The vulnerability is caused due to a boundary error when converting processed URLs from ASCII to Unicode encoding. This can be exploited to cause a stack-based buffer overflow via an invalid URL longer than 4096 bytes.
Successful exploitation may allow execution of arbitrary code.
The vulnerability is reported in versions 2.6.3 and 2.6.4. Prior versions may also be affected.
Solution: Update to version 2.6.5.
