RHBA-2014:1610 - Bug Fix Advisory

Topic

Updated keyutils packages that fix one bug are now available for Red Hat
Enterprise Linux 6.

Description

The keyutils packages provide utilities to control the Linux kernel key
management facility and to provide a mechanism by which the kernel calls up to
user space to get a key instantiated.

This update fixes the following bug:

• Previously, the "keyctl show" command incorrectly displayed an abbreviated

tree of nested keyrings and therefore the keyring trees that were more than two
keyrings deep were not fully displayed. This bug has been fixed and "keyctl
show" now displays entire keyring trees as expected.

Moreover, the "keyctl show" command did not expand the field width to show the
full decimal key ID. With this update, the key ID field is expanded correctly.

Also, the maximum size of input data for the "keyctl padd" command and other
pipe-in commands has been increased to 1MB.

Finally, the "keyctl padd" command as well as other pipe-in commands have been
modified not to specially handle zero-value bytes in binary input. (BZ#1075652)

Users of keyutils are advised to upgrade to these updated packages, which fix
this bug.
