Fun with packages management

Post by drknut » 2019/05/19 09:53:40

Hello All,

In the context of trying to work around the broken yum-security plugin, I'd like to correlate the output of

Code: Select all

yum changelog updates

wget-1.14-18.el7_6.1.x86_64              updates                                                        
* Fri Apr  5 14:00:00 2019 Tomas Hozza <thozza@redhat.com> - 1.14-18.1                                  
- Fix CVE-2019-5953 (#1696733)                                                                          

* Wed May  9 14:00:00 2018 Tomas Hozza <thozza@redhat.com> - 1.14-18                                    
- Fix CVE-2018-0494 (#1576106)                                                                          

* Mon Apr 23 14:00:00 2018 Tomas Hozza <thozza@redhat.com> - 1.14-17                                    
- Fix segfault when Digest Authentication header is missing 'qop' part (#1545310)   
with the output of

Code: Select all

yum info wget

Is there a naming rule that explain the release numbers

Code: Select all

changelog  yum info
   18       18.el7
   18.1     18.el7_6.1
where does the "_6" come from ?

Incidentally we note that the CVE fix has shrinked the package by nearly 75 %.

The size reported by yum info varies - if it's installed then it shows you how much space the files take up, if it isn't then it shows you the size of the package itself.

Thanks for this explanation.

And for the release naming ? Any hint ?

Inherited from upstream. That's what RH called it in RHEL, that's what we build it as.

The only exceptions to that are packages with ".centos." in their names which indicates that they've been modified to debrand them by CentOS. In those cases, as an example, RHEL's httpd-2.4.6-67.el7_4.6.x86_64.rpm becomes httpd-2.4.6-67.el7.centos.6.x86_64.rpm
