A buffer overflow in HAProxy might allow an attacker to execute arbitrary code.

HAProxy is a TCP/HTTP reverse proxy for high availability environments.
It was discovered that HAProxy incorrectly handled certain HTTP/2 headers.
A remote attacker, by sending a specially crafted HTTP/2 request, could possibly execute arbitrary code with the privileges of the process, or cause a Denial of Service condition.
Disable HTTP/2 support.
All HAProxy 2.0.x users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=net-proxy/haproxy-2.0.13:0/2.0"
All other HAProxy users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=net-proxy/haproxy-2.1.4"
A vulnerability in HAProxy might lead to remote execution of arbitrary code.

A buffer overflow in HAProxy may allow execution of arbitrary code.
| Package | Arch | Vulnerable | Unaffected |
|---|---|---|---|
| net-proxy/haproxy | * | < 1.4.21 | >= 1.4.21 |
HAProxy is a TCP/HTTP reverse proxy for high availability environments.
A boundary error in HAProxy could cause a buffer overflow when header rewriting is enabled and the configuration sets global.tune.bufsize to a value greater than the default (16384 bytes).
A remote attacker could possibly execute arbitrary code with the privileges of the process or cause a Denial of Service condition.
There is no known workaround at this time.
All HAProxy users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=net-proxy/haproxy-1.4.21"
