DESCRIPTION:
Javier Fernández-Sanguino Peña has reported a vulnerability in
aStats, which can be exploited by malicious, local users to perform
certain actions on a vulnerable system with escalated privileges.
The vulnerability is caused due to the astats script creating some
PNG images and the aStats-Graphic-Signature-Generation file
insecurely. This can be exploited via symlink attacks to overwrite
arbitrary files with the privileges of the user running the
vulnerable script.
The vulnerability has been reported in version 1.6.5. Other versions
may also be affected.
SOLUTION:
Grant only trusted users access to affected systems.
PROVIDED AND/OR DISCOVERED BY:
