This could allow an attacker to cause the product to operate on unauthorized files. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

Multiple symlink vulnerabilities in portupgrade before 20041226_2 in FreeBSD allow local users to (1) overwrite arbitrary files and possibly replace packages to execute arbitrary code via pkg_fetch, (2) overwrite arbitrary files via temporary files when portupgrade upgrades a port or package, or (3) create arbitrary zero-byte files via the pkgdb.fixme temporary file.

The bug was discovered 04/12/2005. The weakness was released 04/12/2005 (Website). The advisory is shared at vuxml.org. The identification of this vulnerability is CVE-2005-0610 since 03/01/2005. The exploitation is known to be easy. An attack has to be approached locally. No form of authentication is needed for a successful exploitation. Neither technical details nor an exploit are publicly available.
