Format string vulnerability in War FTP Daemon (warftpd) 1.82 RC 12 allows remote authenticated users to cause a denial of service (crash) via format string specifiers in a LIST command.

Weakness

The product uses a function that accepts a format string as an argument, but the format string originates from an external source.

Affected Software

Name Vendor Start Version End Version
Warftpd Jgaa 1.8.2 1.8.2

Extended Description

When an attacker can modify an externally-controlled format string, this can lead to buffer overflows, denial of service, or data representation problems. It should be noted that in some circumstances, such as internationalization, the set of format strings is externally controlled by design. If the source of these format strings is trusted (e.g. only contained in library files that are only modifiable by the system administrator), then the external control might not itself pose a vulnerability.
