Debian -- Security Information Matt Zimmerman July 22nd, 2003 Debian -- Debian security FAQ - -------------------------------------------------------------------------- Package : fdclone Vulnerability : insecure temporary directory Problem-Type : local Debian-specific: no CVE Ids : CAN-2003-0596 fdclone creates a temporary directory in /tmp as a workspace. However, if this directory already exists, the existing directory is used instead, regardless of its ownership or permissions. This would allow an attacker to gain access to fdclone's temporary files and their contents, or replace them with other files under the attacker's control. For the stable distribution (woody) this problem has been fixed in version 2.00a-1woody3. For the unstable distribution (sid) this problem has been fixed in version 2.04-1.
