Description:
A vulnerability was reported in the xine video player. A local user may be able to gain elevated privileges.
Shaun Colley reported that the script named both 'xine-bugreport' and 'xine-check' uses a temporary file in an unsafe manner. When the script preparse a bug report e-mail message, the '/tmp/xine-bugreport' temporary file is reportedly used for a template but without first checking to see if the file exists.
A local user can create a symbolic link (symlink) from a file on the system to the temporary filename. Then, when a target user runs xine and prepares a bug report to be e-mailed, the symlinked file will be overwritten with the privileges of the target user.
|
Impact:
A local user can cause files to be created or overwritten by a target user with the privileges of the target user. A local user may be able to exploit this to gain elevated privileges on the target system.

Solution:
Mandrake has released a fix.
