Category:Debian Local Security Checks
Title:Debian: Security Advisory for haproxy (DSA-4649-1)
Summary:The remote host is missing an update for the 'haproxy'; package(s) announced via the DSA-4649-1 advisory.
Description:Summary:
The remote host is missing an update for the 'haproxy'
package(s) announced via the DSA-4649-1 advisory.

Vulnerability Insight:
Felix Wilhelm of Google Project Zero discovered that HAProxy, a TCP/HTTP
reverse proxy, did not properly handle HTTP/2 headers. This would allow
an attacker to write arbitrary bytes around a certain location on the
heap, resulting in denial-of-service or potential arbitrary code
execution.

Affected Software/OS:
'haproxy' package(s) on Debian Linux.

Solution:
For the stable distribution (buster), this problem has been fixed in
version 1.8.19-1+deb10u2.

We recommend that you upgrade your haproxy packages.

CVSS Score:
6.5
