NAME

yum security plugin

SYNOPSIS

yum [options] [command] [package ...]

DESCRIPTION

This plugin extends yum to allow lists and updates to be limited using security relevant criteria

added yum commands are:
yum update-minimal

This works like the update command, but if you have the the package foo-1 installed and have foo-2 and foo-3 available with updateinfo.xml then update-minimal will update you to foo-3.
yum updateinfo info
yum updateinfo list
yum updateinfo summary

all of the last three take these sub-commands:
yum updateinfo * all
yum updateinfo * available
yum updateinfo * installed
yum updateinfo * updates

and then:
* <advisory> [advisory...]
* <package>
* bugzillas
* cves
* enhancement
* security
* new-packages

BUGS

The update-minimal command ignores the --obsoletes flag.

The update-minimal command can only directly affect things atm., so if you update pkgA minimally but that requires an update to pkgB then pkgB will be updated to the newest version by the depsolver. Also the above will happen even if you've also minimally updated pkgB, if either the direct (minimal) update for pkgB happens after or if the minimal update for pkgB doesn't satisfy the requirements of pkgA.

The main "problem" is that if the data is not correct the plugin cannot work correctly. For instance "--bz 123" will not fix BZ 123 if a package is updated to fix that BZ without referencing that it does so in the updateinfo.xml.
