## Description:

This update for apptainer fixes the following issues

  * CVE-2026-24137: github.com/sigstore/sigstore/pkg/tuf: legacy TUF client
    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).
  * CVE-2026-33814: golang.org/x/net/http2: infinite loop in HTTP/2 transport

  * CVE-2026-34986: github.com/go-jose/go-jose/v4,github.com/go-jose/go-jose/v3:
    crafted JWE input with a missing encrypted key can lead to a denial of
    service (bsc#1262956).
  * CVE-2026-39821: golang.org/x/net/idna: failure to reject ASCII-only
    Punycode-encoded labels allows for validation bypass and privilege
    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-2026-39831: bypass of FIDO/U2F security keys physical interaction in
    golang.org/x/crypto/ssh (bsc#1266202).
  * CVE-2026-39832: agent constraints dropped when forwarding keys in
    golang.org/x/crypto/ssh/agent (bsc#1266202).
  * CVE-2026-39833: key constraints not enforced in
    golang.org/x/crypto/ssh/agent (bsc#1266202).
  * CVE-2026-39834: infinite loop on large channel writes in
    golang.org/x/crypto/ssh (bsc#1266202).
  * CVE-2026-39835: server panic during CheckHostKey/Authenticate in
    golang.org/x/crypto/ssh (bsc#1266202).
  * CVE-2026-42508: auth bypass via unenforced @revoked status in
    golang.org/x/crypto/ssh/knownhosts (bsc#1266202).
  * CVE-2026-46595: VerifiedPublicKeyCallback permissions skip enforcement in
    golang.org/x/crypto/ssh (bsc#1266202).
  * CVE-2026-46597: byte arithmetic causes underflow and panic in
    golang.org/x/crypto/ssh (bsc#1266202).
  * CVE-2026-46598: pathological inputs can lead to client panic 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`.
