The remote host is affected by the vulnerability described in GLSA-200704-03 (OpenAFS: Privilege escalation)
Benjamin Bennett discovered that the OpenAFS client contains a design flaw where cache managers do not use authenticated server connections when performing actions not requested by a user.
Impact :
If setuid is enabled on the client cells, an attacker can supply a fake FetchStatus reply that sets setuid and root ownership of a file being executed. This could provide root access on the client. Remote attacks may be possible if an attacker can entice a user to execute a known file. Note that setuid is enabled by default in versions of OpenAFS prior to 1.4.4.
Workaround :
Disable the setuid functionality on all client cells. This is now the default configuration in OpenAFS.
