Hello,
this is a heads-up only, nothing we can do:
Ubuntu backported 2e4ba6a5708 ("BUG/MAJOR: h1-htx: report an error on
a too long chunk-size line") for CVE-2026-110354 to Haproxy 2.4 for
their Ubuntu 22.04 repositories that will be EOL in April 2027.
Apparently that backport introduced a regression that is breaking
legitimate requests:
