An update that solves one vulnerability can now be installed.

## Description:

This update for guava fixes the following issue:

  * CVE-2026-102554: Allocation of resources without limits or throttling
    (CWE-770) during Java object deserialization allows an attacker to cause a
    Denial of Service via OutOfMemoryError (bsc#1284985).

Changes for guava:

  * Adapt the generated OSGi data to reality
  * Upgrade to guava 33.7.2
  * Changes of 33.7.2
  * collect: Changed MapMaker, CompactHashMap, and CompactHashSet
    deserialization to avoid eagerly allocating as much memory as a
    serialization payload requests (bsc#1284985, CVE-2026-102554)
  * Changes of 33.7.1
  * removes the Multi-Release line from our jar manifest, fixing an issue under
    Java 9 and 10 that was introduced to guava-jre in version 33.7.0.
  * Changes of 33.7.0
  * Guava module-info.class is now present at the root of the jar instead of
    under a multi-release root. This prevents the jar from containing a file at
    META-INF/versions/9/OSGI-INF/ /MANIFEST.MF, which occasionally causes
    trouble for some users
  * collect: Changed some ImmutableMap implementations to create a new,
    lightweight object on each call to view methods like keySet(), rather than
    creating and storing that object during the first call for reuse later. This
    is likely to slightly improve performance for some users, but it could lead
    to regressions in unusual cases, such as repeatedly calling
    asMultimap().inverse() on the same ImmutableMap instance.
  * net: Added HttpHeaders constant for on-prefetch-activation.
  * net: Added MediaType constants for application/yaml and application/x-pem-
    file.
  * util.concurrent: Fixed ExecutionSequencer queue stall when delegate executor
    throws RejectedExecutionException.
  * Changes of 33.6.0
  * Migrated some classes from finalize() to PhantomReference in preparation for
    the removal of finalization.
  * cache: Deprecated CacheBuilder APIs that use TimeUnit in favor of those that
    use Duration.
  * collect: Added toImmutableSortedMap collectors that use the natural
    comparator.
  * collect: Changed ConcurrentHashMultiset, ImmutableMultimap, and TreeMultiset
    deserialization to avoid mutating final fields. In extremely unlikely
    scenarios in which an instance of that type contains an object that refers
    back to that instance, this could lead to a broken instance that throws
    NullPointerException when used.
  * graph: Removed @Beta from all APIs in the package.
  * graph: Added support to Graphs.transitiveClosure() for different strategies
    for adding self-loops.
  * graph: Added an asNetwork() view to Graph and ValueGraph.
  * hash: Added BloomFilter.serializedSize().
  * net: Added HttpHeaders.CDN_CACHE_CONTROL.
  * Changes of 33.5.0
  * For users of guava-gwt: Google has moved off GWT internally. We plan to
    continue to release guava-gwt for users of GWT and J2CL, but the artifact is
    no longer tested for GWT-specific issues, and we have limited resources to
    fix any unexpected issues that might arise. While we do not anticipate any
    specific problems, we can't guarantee how long support will continue.
  * Listed the JSpecify annotations as an optional dependency in our OSGi
    metadata.
  * cache: Improved the handling of exceptions from compute functions in
    Cache.asMap(). (We do still recommend using Caffeine rather than
    com.google.common.cache.)
  * collect: Improved Iterators.mergeSorted() to preserve stability for equal
    elements.
  * math: Added saturatedAbs methods to IntMath and LongMath.
  * net: Added image/avif to MediaType.
  * util.concurrent: Added Striped.custom.
