|Description||The session_start function in ext/session in PHP 4.x up to 4.4.7 and 5.x up to 5.2.3 allows remote attackers to insert arbitrary attributes into the session cookie via special characters in a cookie that is obtained from (1) PATH_INFO, (2) the session_id function, and (3) the session_start function, which are not encoded or filtered when the new session cookie is generated, a related issue to CVE-2006-0207.|

The information below is based on the following data on fixed versions.
this does not affect default installs, only those who have written
custom session handlers (which isn't *that* uncommon though), and
also may not work if other cookie values are set.
fix sneaked into php 5.2.3 sans-mention:
fixed in php4/etch, php5/etch, php4/sarge svn
