Bugfix release with large number of (security) fixes.
HAProxy 2.6.32 was released on 2026/07/29. It added 33 new commits
after version 2.6.31.
As for the 2.8.27, the announce is an expurgated copy-paste of the 3.4.3
announce:
* stats: Two issues about the stats page, reported by Red Hat/AISLE
Research, were fixed.
Proxies updated through the stats page while in "stats admin" mode were
not subject to the "stats scope" filtering, meaning a scope meant to
restrict which proxies are visible/actionable could be silently bypassed
on POST requests.
Separately, POST requests to the stats interface did not validate that the
Origin (or Referer) header matched the Host, which is now checked to
mitigate CSRF attacks.
* ssl-gencert: A memory leak on every certificate generation was fixed.
Two temporary buffers were not freed after generating a certificate on the
fly, leaking memory each time a new SNI triggered certificate
generation. This issue was reported by Red Hat/AISLE Research.
* sample/protobuf: buffer overflows after pointer-shift converters, reported
by Red Hat/AISLE Research and Charles Vosburgh, were fixed.
Several converters (protobuf/ungrpc field extraction, ltrim())
move the sample's data pointer forward on success but did not shrink the
sample's recorded buffer capacity accordingly. A converter chained
afterwards that relies on that capacity (e.g. padding via memset()) could
then write past the end of the buffer, leading to heap corruption or a
worker crash. All the affected converters now adjust the capacity
together with the pointer.
* protobuf: A nested-path validation bypass reported by Red Hat/AISLE
Research was fixed.
The protobuf field lookup used for the protobuf()/ungrpc() converters did
not strictly enforce hierarchical boundaries, so a flat sibling field
could incorrectly satisfy a nested-path lookup (e.g. matching a root-level
field as if it were nested under a parent). The lookup was rewritten as a
strict, non-recursive path walker that correctly bounds each nesting
level.
Separately, a crash because of deprecated protobuf group wire types was
fixed. These wire types are now explicitly rejected.
* http-fetch: Two crashes reachable from health-check configurations were
fixed.
"res.body"/"res.hdr"/... and similar response fetches assumed the
health-check receive buffer always held an HTX message, which is only true
for actual HTTP checks; on a plain TCP check, a hostile/misbehaving server
could craft the first bytes of its reply to be misinterpreted as HTX
internal fields, causing a wild read and worker crash (or leaking
arbitrary process memory).
Separately, "capture.req.hdr"/"capture.res.hdr" only validated the upper
bound of their index argument, so a negative capture id was accepted at
boot and dereferenced an out-of-bounds array entry at runtime, crashing
the worker on the very first request.
* slz: Several issues were fixed in the SLZ library.
A stream alternating many literals in the 144-255 range with cheap
back-references could keep inflating indefinitely instead of falling
back to a stored block, exceeding the library's documented worst-case
output size by several percent. A new accounting mechanism now bounds
this overhead. Practical impact on haproxy requires tune.bufsize above
~43 kB with the default reserve.
Five small correctness fixes inherited from upstream libslz were also
backported: Avoid reading up to a few bytes past the end of very short
inputs on architectures without fast unaligned access; stop appending an
extra, misplaced block to an already-finished deflate/gzip/zlib stream
(which could corrupt the trailing checksum in ~2% of fuzzed streams); fix
the Adler32 checksum accumulator sign handling on 32-bit systems
(affecting the zlib format only); avoid an undefined-behaviour signed left
shift when assembling input words byte by byte; and use the exact bit cost
when deciding whether to emit the last literals of a block as a stored
block, avoiding compressed output slightly larger than the documented
worst case.
* peers: A heap overflow when replicating large stick-table dictionary
entries was fixed.
peer_prepare_updatemsg() never verified that a stick-table entry's
dictionary value (e.g. server_key, up to ~16 kB) actually fit in the
update message being built. Since the peers protocol is plain-text and
unauthenticated, a rogue or compromised peer could plant an oversized
entry that overflows the 16 kB trash buffer as soon as the victim
replicates ("teaches") it, confirmed as a heap-buffer-overflow write. The
function now checks the available room before encoding and fails cleanly
if it doesn't fit. This was reported and fixes by Matt Suiche from Tolmo
Inc.
And, as usual, the bunch of minor fixes here and there, mainly raised during
AI-assisted code reviews. Most were never noticed:
* HTX API: Some bugs about how the HTX API was used were fixed here and
there.
* http-act: Double-frees and a couple of state bugs on parsing errors were
fixed.
* http-fetch/http-ana/http-htx: Few out-of-bounds reads were fixed.
* http-conv: The last input character could be lost when calling url-dec
converter, when the input buffer was full. This was fixed by failing the
converter in that case.
* mux-h1: An extra 200ms delay was observed on some H2-to-H1 messages
because the end of the message was not always properly detected. This
case is now properly handled.
* sample: An edge case in be2hex() was fixed.

With this the test verifies not only that Apache can work in
principle, but also that it works with a read-only rootfs. Because of
the read-only rootfs the test itself cannot write to /root, so store
the test download in /tmp.

The previous configuration placed both logs and PID file in /var/logs,
which is not writable with a read-only rootfs (e.g. squashfs), as well
as non-standard. Starting HTTPD during boot failed with:
(30)Read-only file system: AH00091: httpd: could not open error log file /var/logs/error_log.
AH00015: Unable to open logs
An additional issue was that the Buildroot-default --prefix=/usr
override meant various Apache-internal directories (e.g. htdocs) were
placed directly in /usr. Note that the upstream default prefix is
/usr/local/apache2, not /usr/local.
Using the "Debian" layout provides a standard-compatible layout with
logs in /var/log/apache2 and PID file in /var/run/apache2 (both in
tmpfs with the default Buildroot fstab). Both directories need to
exist when the server starts, so handle that in the init script.

Changes since OpenSSH 10.4
==========================
This release contains a number of security fixes and small bugfixes.
Security
========
* ssh-agent(1): fix an interaction between agent locking and the
session-bind@openssh.com extension that is used to identify
forwarded agents. These binding requests were refused when the
agent was locked, with the result that operations that were
intended to be limited to local use only could be performed
remotely, including the ability to add PKCS#11 tokens and make
use of keys that had destination restrictions applied.
Reported by sn0x-sharma
* ssh(1): avoid potential realloc use-after-free in the client if a
remote forwarding is added via the local session multiplexing
socket while a remote forwarding open request is pending with the
server. Report and fix from Brian Mingus of Cognatory
* sshd(8): make the authorized_keys "restrict" keyword apply
correctly to tunnel forwarding too (which is administratively
disabled by default). Reported by Erichen, Institute of Computing
Technology, Chinese Academy of Sciences

host-flex/host-bison are needed when building GCC from Git or from a
snapshot, not from release tarballs. The condition for the dependency
was actually incorrect: it was needed for the ARC-specific gcc
version (BR2_GCC_VERSION_ARC) but not for the ARC architecture in
general: building upstream GCC release tarballs for ARC does not
require host-flex/host-bison.

A new (and hopefully definitive) CPE is to be used for TF-A:
cpe:2.3:o:trustedfirmware:trusted_firmware-a:
as reported in TF-A directly[1]. NVD correctly reports[2] the new CPE
deprecates the "old" one Buildroot was using.
CVEs for projects under the TrustedFirmware umbrella are now seemingly
handled under the CPE vendor "trustedfirmware".

Changes:
Security and robustness release. Notable cramfsck changes:
* Reject dirent names containing "/", "." or ".." to close a path
traversal during `cramfsck -x` (reported in issue #12).
* Open regular files with O_CREAT|O_EXCL during extraction to
prevent duplicate-dirent attacks from truncating files reached
via a previously-extracted symlink.
* Fix outbuffer NUL termination and a 1-byte overflow in
do_symlink when running with both -v and -x.
* Harden romfs_read against truncated/malformed images by
zero-filling the window buffer and checking lseek/read returns.
* Reject directory entries that extend past their parent's size.
Documentation: README now documents cramfsck and lists all current
mkcramfs options; stale hard-link and endianness claims corrected;
NOTES trimmed of the 25-year-old Future Development section.
