## Description:
This update for apptainer fixes the following issues

allows for arbitrary file writes with target cache path traversal
(bsc#1264177).
* CVE-2026-33186: google.golang.org/grpc: authorization bypass due to improper
validation of the HTTP/2: path pseudo- header (bsc#1260311).

escalation (bsc#1266656).
* CVE-2026-39827: memory leak when rejecting channels can lead to DoS in
golang.org/x/crypto/ssh (bsc#1266202).
* CVE-2026-39828: bypass of certificate restrictions in
golang.org/x/crypto/ssh (bsc#1266202).
* CVE-2026-39829: pathological RSA/DSA parameters may cause DoS in
golang.org/x/crypto/ssh (bsc#1266202).
* CVE-2026-39830: client can cause server deadlock on unexpected responses in

golang.org/x/crypto/ssh (bsc#1266202).
* CVE-2026-39835: server panic during CheckHostKey/Authenticate in

golang.org/x/crypto/ssh/agent (bsc#1266202).
* CVE-2026-48785: incorrect path matching for limit container paths directive
(bsc#1267982).
Changes for apptainer:
* Update apptainer to version v1.5.1
* Work around segmentation fault sometimes seen while `mksquashfs` under proot
is creating a SIF file.
* Update bundled PRoot to version 5.4.0-rootless.3 in order to fix a problem
where SIF files could be corrupted when `mksquashfs` died with a signal. The
proot command was not passing back an error exit code.
* Updated bundled `squashfuse_ll` to version 0.6.2 in order to fix a crash
sometimes seen with apptainer in unprivileged docker.
* Update bundled fuse2fs to version 1.47.4 instead of patching the bugs in
1.47.3.
* Fix a crash that happened when `/etc/resolv.conf` was a symlink while
building from a definition file using the localimage bootstrap.
* Support hosts that have an /etc/resolv.conf symlink pointing to `../run` in
addition to `/run`.
* Change the download-dependencies script to skip downloading the PRoot source
code on architectures that it is known to not support (that is: ppc _, s390_
, and riscv*). In those situations Apptainer will skip trying to compile and
run proot. As a result original owners and groups of files will not be
preserved in SIF images built by unprivileged users, as was the case for all
architectures prior to 1.5.0.
* Fix panic encountered during progress bar update while pulling image.
* Fix fakeroot overwriting root's username in `/etc/passwd` with the host
user's name, a regression introduced in v1.5.0.
* Add nonested flag for --mount specifications to prevent individual bind
mounts from being passed to nested containers via `APPTAINER_BIND`.
