Affected software and risk
==========================
Vulnerability concerning OpenSSL
Package : OpenSSL
CVE ID : CVE-2022-0778
Bug ID :
CVSS Score :
A DoS vulnerability has been announced in OpenSSL, affecting OpenSSL versions
1.0.2, 1.1.0, 1.1.1 and 3.0. [R 1] EGI SVG considers this vulnerability to have
a limited risk to EGI sites.
Actions required/recommended
============================
For most sites no urgent action is recommended.
If sites find they are running a vulnerable version of OpenSSL they should
consider updating to avoid a DoS at their sites.
If anyone becomes aware of any situation where this vulnerability has a
significant impact on the EGI infrastructure then please inform EGI SVG.
Component installation information
==================================
If necessary, see your relevant software provider.
Affected software details
=========================
OpenSSL versions 1.0.2, 1.1.0, 1.1.1 and 3.0. [R 1]
RHEL7 and RHEL8 and derivatives do not appear to be affected [R 2]
Ubuntu [R 3] and Debian [R 4] have some limited exposure.
More information
================
The EGI SVG is issuing this INFORMATION because some sites are asking about
it, it is being talked about a lot, and other infrastructures are issuing
an advisory.
The EGI SVG considers the possibility of a DoS at one site to be less serious
than, for example, a privilege escalation vulnerability.
The combination of this being a DoS and their being little likelihood of many
sites being affected means it is not considered to be a serious risk to EGI.
