Hi All,

https://www.suse.com/security/cve/CVE-2020-25632

https://www.suse.com/security/cve/CVE-2021-20233

The CVE webpage does not record sles11sp3 related information,

Does this grub2 vulnerability affect the sles11sp3 system,whether it is planned to be repaired? thank you very much.

Thanks,
Mengsu
Comment 20 Marcus Meissner 2021-05-18 08:44:18 UTC 
SLES 11 SP3 LTSS is end of life.

There are some contracts (which you probably have) on "reactive support" , but you need to request fixes sepreately.

And we do not state affectedness for these proucts that have left regular LTSS.

Hello Marcus,

Ok, thanks for the reply, I will apply for PTF repair separately.

Thanks,
