Description Sam James archtester Gentoo Infrastructure gentoo-dev Security 2020-04-02 19:12:15 UTC 
Description:
"In hpack_dht_insert in hpack-tbl.c in the HPACK decoder in HAProxy 1.8 through 2.x before 2.1.4, a remote attacker can write arbitrary bytes around a certain location on the heap via a crafted HTTP/2 request, possibly causing remote code execution."
