Previous releases have included source RPMs that made it easier for us to build
RPMs to deploy to our Red Hat-based servers. I was hoping it maybe had just
not yet been released yet, but there still isn’t a source RPM for 1.6.23. It
looks like one was built for 1.6.24.4, so I may just end up deploying that
since we do not use any of the backup utilities. I know that support for RPMs
from OpenAFS is something that’s been discussed for a long time, but I hadn’t
seen any official announcement (unless I missed it) that indicated that they
would no longer be created.
For any other folks using Red Hat – what are you doing for deploying OpenAFS?
Are there any repos out there equivalent to the Ubuntu PPA?

Subject: [OpenAFS] OpenAFS Security Releases 1.8.2, 1.6.23 available
The OpenAFS Guardians are happy to announce the availability of
Security Releases OpenAFS 1.8.2 and 1.6.23.
Source files can be accessed via the web at:
https://www.openafs.org/release/openafs-1.8.2.html
https://www.openafs.org/release/openafs-1.6.23.html
or via AFS at:
UNIX: /afs/grand.central.org/software/openafs/1.8.2/
UNC: \\afs\grand.central.org\software\openafs\1.8.2\
UNIX: /afs/grand.central.org/software/openafs/1.6.23/
UNC: \\afs\grand.central.org\software\openafs\1.6.23\
These releases include fixes for three security advisories,
OPENAFS-SA-2018-001, OPENAFS-SA-2018-002, and OPENAFS-SA-2018-003.
OPENAFS-SA-2018-001 only affects deployments that run the 'butc' utility
as part of the in-tree backup system, but is of high severity for
those sites which are affected -- an anonymous attacker could replace
entire volumes with attacker-controlled contents.
OPENAFS-SA-2018-002 is for information leakage over the network via
uninitialized RPC output variables. A number of RPCs are affected,
some of which require the caller to be authenticated, but in some cases
hundreds of bytes of data can be leaked per call. Of note is that
cache managers are also subject to (kernel) memory leakage via
AFSCB_ RPCs.
OPENAFS-SA-2018-003 is a denial of service whereby anonymous attackers
can cause server processes to consume large quantities of memory for
a sustained period of time.
Please see the release notes and security advisories for additional details.
The changes to fix OPENAFS-SA-2018-001 require behavior change in both
butc(8) and backup(8) to use authenticated connections; old and new
versions of these utilities will not interoperate absent specific
configuration of the new tool to use the old (insecure) behavior.
These changes also are expected to cause backup(8)'s interactive mode
to be limited to only butc connections requiring (or not requiring)
authentication within a given interactive session, based on the initial
arguments selected.
Bug reports should be filed to
openafs-b...@openafs.org<mailto:openafs-b...@openafs.org>.
