CVE-2018-18385
Asciidoctor v1.5.7.1 allows remote attackers to cause a denial of service
(infinite loop), as demonstrated by web applications that deliver untrusted
input to this product, because Parser#next_block misuses a "while true"
statement.

Hi Stephan,
I wasn't able to find any additional information or patches. The only information is the link to the upstream issue.
Comment 4 Robert Frohl 2018-10-19 11:20:14 UTC 
There is now a patch by upstream, but it does not look like it would apply easily to the version we ship:

Comment 10 Andrea Mattiazzo 2024-07-19 12:51:41 UTC 
All done, closing.
