Man2Html contains a flaw that may allow a local attacker to gain access to unauthorized privileges. By creating a symbolic link in the /tmp directory pointing to an arbitrary file, a local attacker can overwrite the file and elevate privilege. This flaw may lead to a loss of availability and integrity.
Upgrade to version 3.0.1 or higher, as it has been reported to fix this vulnerability. An upgrade is required as there are no known workarounds.
