Nicotine+ is a graphical client for the Soulseek peer-to-peer network. Prior to version 3.3.11, a modified remote client can send zlib-compressed peer messages containing a decompression bomb, exhausting available memory of the recipient's operating system. This issue has been patched in version 3.3.11.
