Discussion

Debian lustre-tests Insecure Temporary File Creation Vulnerability

Debian 'lustre-tests' 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.

Debian 'lustre-tests' 1.6.5 and 1.6.5.1 are vulnerable; other versions may also be affected.
