Security update for haproxy
Notes
Title of the patch
Security update for haproxy
Description of the patch
This update for haproxy to version 2.0.10 fixes the following issues:
HAProxy was updated to 2.0.10
Security issues fixed:
- CVE-2019-18277: Fixed a potential HTTP smuggling in messages
with transfer-encoding header missing the 'chunked' (bsc#1154980).
- Fixed an improper handling of headers which could have led to
injecting LFs in H2-to-H1 transfers creating new attack space (bsc#1157712)
- Fixed an issue where HEADER frames in idle streams are not rejected and
thus trying to decode them HAPrpxy crashes (bsc#1157714).
Other issue addressed:
- Macro change in the spec file (bsc#1082318)

The impact was limited but if combined with the \"http-reuse always\" setting, it could be used to help construct an HTTP request smuggling attack against a vulnerable component employing a lenient parser that would ignore the content-length header as soon as it saw a transfer-encoding one (even if not entirely valid according to the specification).",
