Description

Sysstat contains a flaw that may allow a malicious user to perform a symlink attack. The issue is due to the post script creating insecure temporary files. By creating a symbolic link for a file in /tmp to an arbitrary file on the system, a local attacker can overwrite arbitrary files on the system, resulting in a loss of integrity.
