Ubuntu Linux - [updated libpng in Oracle Java]

The remote Fedora 43 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2026-a109a9ac2c advisory.

    * updated to 1.6.58
    * 1.6.58 is released with a fix for a simple correctness bug (not a security issue) this time:
    png_get_PLTE() returns stale palette data when either gamma correction or alpha-compositing is the only     transform applied. Like the issues addressed in the previous release, this bug was a regression introduced     in the fix for CVE-2026-33416 in 1.6.56.
    * 1.6.57 is released with fixes for the following security vulnerability:
    - CVE-2026-34757 (medium severity): Use-after-free memory bug in the chunk setter API. The hIST variant     has existed since version 1.0.9, but the PLTE and tRNS ones are regressions introduced in the fix for     CVE-2026-33416 in 1.6.56 (oops).

Tenable has extracted the preceding description block directly from the Fedora security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
