Discussion

fence 'fence_manual' Insecure Temporary File Creation Vulnerability

The 'fence' program creates temporary files in an insecure manner.

An attacker with local access could potentially exploit this issue to perform symbolic-link attacks, overwriting arbitrary files in the context of the affected application.

Successfully mounting a symlink attack may allow the attacker to delete or corrupt sensitive files, which may result in a denial of service. Other attacks may also be possible.

Versions prior to 'fence_manual' from fence 2.03.09 are affected.
