Description

This update for haproxy to version 1.8.14 fixes the following issues :

These security issues were fixed :

 - CVE-2018-14645: A flaw was discovered in the HPACK decoder what caused an out-of-bounds read in hpack_valid_idx() that resulted in a remote crash and denial of service (bsc#1108683)

 - CVE-2018-11469: Incorrect caching of responses to requests including an Authorization header allowed attackers to achieve information disclosure via an unauthenticated remote request (bsc#1094846).

These non-security issues were fixed :

 - Require apparmor-abstractions to reduce dependencies (bsc#1100787)

 - hpack: fix improper sign check on the header index value

 - cli/threads: protect all 'proxy' commands against concurrent updates

 - lua: socket timeouts are not applied

 - ssl: Use consistent naming for TLS protocols

 - dns: explain set server ... fqdn requires resolver

 - map: fix map_regm with backref

 - ssl: loading dh param from certifile causes unpredictable error.

 - ssl: empty connections reported as errors.

 - cli: make 'show fd' thread-safe
