Security update for haproxy

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)

Описание

A flaw was found in HAProxy before 2.0.6. In legacy mode, messages featuring a transfer-encoding header missing the "chunked" value were not being correctly rejected. 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).
