Discussion
Pithos '/tmp/pithos.debug.log' Insecure Temporary File Creation Vulnerability
Pithos creates a temporary file in an insecure manner.
An attacker with local access could 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 Pithos 0.3.5 are vulnerable.
