sysstat post and trigger scripts symlink attack
| sysstat-post-trigger-symlink (15428) |  Medium Risk |
Description:
sysstat could allow a local attacker to launch a symlink attack. The post and trigger scripts create insecure temporary files. A local attacker could create a symbolic link for a file in /tmp to an arbitrary file on the system, which could allow the attacker to overwrite arbitrary files on the system.
Consequences:
File Manipulation
