GLSA-200704-03 : OpenAFS: Privilege escalation

High Nessus Plugin ID 24936


The remote Gentoo host is missing one or more security-related patches.


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.


All OpenAFS users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=net-fs/openafs-1.4.4'
