Synopsis

The remote openSUSE host is missing one or more security updates.

Description

The remote openSUSE 16 host has packages installed that are affected by multiple vulnerabilities as referenced in the openSUSE-SU-2026:22034-1 advisory.

- CVE-2026-18401: Number Length Constraint Bypass in Async Parser Can Lead to Potential Processing Time Issues (bsc#1273856).
- CVE-2026-19032: deserializer for `java.nio.file.Path` resolves attacker-supplied URIs without restricting the URI scheme (bsc#1277883).
- CVE-2026-68494: Async parser maxNumberLength bypass via chunked digit accumulation (bsc#1273857).
- CVE-2026-68497: An unauthenticated attacker can therefore submit a single request of a few megabytes (bsc#1280125).
- CVE-2026-68498: Enforce maxNameLength incrementally in ReaderBasedJsonParser (bsc#1282641).
- CVE-2026-83557: incomplete `PolymorphicTypeValidator` denylist allows for arbitrary `Comparable` deserialization (bsc#1278008).
- CVE-2026-89407: Optimize NumberInput.looksLikeValidNumber (bsc#1282645).
- CVE-2026-89425: `UTF8DataInputJsonParser._reportInvalidToken()`lacks `maxErrorTokenLength` limit, which allows for unbounded `StringBuilder` growth and can lead to a DoS when malformed tokens are processed (bsc#1282505).
- CVE-2026-91776: `TypeDeserializerBase._findDeserializer()` caches the resolved deserializer under the raw, attacker- supplied type ID, which can lead to unbounded cache growth under certain configurations (bsc#1282491).
- CVE-2026-91777: forward-reference completion for `@JsonIdentityInfo` object IDs performs a linear scan of the pending- reference accumulator for every resolved ID, which can lead to quadratic CPU work during deserialization (bsc#1282492).
