The remote AlmaLinux 10 host has packages installed that are affected by multiple vulnerabilities as referenced in the ALSA-2026:9693 advisory.

    * JDK: Enhance crypto algorithm support (CVE-2026-22007)
      * JDK: Improved Arena allocations (CVE-2026-22008)
      * JDK: Improve Kerberos credentialing (CVE-2026-22013)
      * JDK: Enhance Path Factories Redux (CVE-2026-22016)
      * JDK: Enhance Zip file reading (CVE-2026-22018)
      * JDK: Enhance certificate chain validation (CVE-2026-22021)
      * JDK: Updating FreeType 2.14.1 (CVE-2026-23865)
      * JDK: Enhance TLS connection handling (CVE-2026-34282)
      * JDK: Enhance key generation (CVE-2026-34268)


    This release also updates a number of third-party libraries included in the JDK. The libraries themselves     are affected by the following CVEs, but this is not a statement that the JDK itself is affected:

      * giflib: Denial of Service via buffer overflow in EGifGCBToExtension (CVE-2026-26740)
      * libpng: Information disclosure and denial of service via out-of-bounds read/write in Neon palette     expansion (CVE-2026-33636)
      * libpng: Arbitrary code execution due to use-after-free vulnerability (CVE-2026-33416)


    Bug Fix(es):

      * When copying files, OpenJDK 25 prefers to use the copy_file_range native function for performance     reasons, only falling back to sendfile when this fails. However, in previous OpenJDK 25 releases, a     response of EOPNOTSUPP (operation not supported) did not cause the JDK to fall back to sendfile. This is     rectified in this release. (AlmaLinux-169939, AlmaLinux-169937)

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - Buffer Overflow vulnerability in giflib v.5.2.2 allows a remote attacker to cause a denial of service via     the EGifGCBToExtension overwriting an existing Graphic Control Extension block without validating its     allocated size. (CVE-2026-26740)

Note that Nessus relies on the presence of the package as reported by the vendor.
