description |
After looking through the source it seems there is a bug in all current ruby3.X packages affecting at least versions >22.04 that causes segfault relatively rarely. Even though rare with repetitions running small wrappers it will be seen quite a bit, up to dozens of times in a day.
There exists a patch upstream, could that be picked to Ubuntu repo(s)?

[Impact]
Users might face a segfault when using ruby_free.
[Test Plan]
# apt update && apt install -y ruby ruby-nokogiri
# cat > reproducer.rb <<EOF
require 'nokogiri'
# must have an error in it to cause pthread_setspecific to be called
html = "<div foo='asdf>asdf</div>"
Thread.new { Nokogiri::HTML4::Document.parse(html) }
sleep 3 # THREAD_CACHE_TIME
exit 0
EOF
# while true; do ruby reproducer.rb; done
After a while (this may take several minutes to manifest) I got the reported error:
[BUG] Segmentation fault at 0x0000000000000440[BUG] Segmentation fault at 0x0000000000000440

The fixed package should not segfault under this condition.
[Where Problems could occur]
The upstream patch to fix this tries to address a timing issue, where depending on the order of things might cause a segfault. The assumption might not be true and users could still get a segfault under some very specific scenario that was not initially considered.
[Original Description]
After looking through the source it seems there is a bug in all current ruby3.X packages affecting at least versions >=22.04 that causes segfault relatively rarely. Even though rare with repetitions running small wrappers it will be seen quite a bit, up to dozens of times in a day.
There exists a patch upstream, could that be picked to Ubuntu repo(s)?
