security advisory update debian remote access information disclosure haproxy

Summary

HAProxy formerly accepted the "#" (ie. the "pound" or "hash") symbol
as part of a URI component. This might have allowed remote attackers
to obtain sensitive information upon HAProxy's misinterpretation of a
"path_end" rule, such as by routing "index.html#.png" to a static
server.

For Debian 10 buster, this problem has been fixed in version
1.8.19-1+deb10u5.

We recommend that you upgrade your haproxy packages.

For the detailed security status of haproxy please refer to
its security tracker page at:
