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

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

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

  - The vulnerability exists due to an out-of-bounds write flaw in the RemoteIo::Impl::populateBlocks()     function. When Exiv2 processes network-hosted metadata via a remote URL instead of a local file, it fails     to safely validate memory bounds during block structure allocation, enabling potential memory corruption     or execution disruption.  (CVE-2026-68546)

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

The version of Exiv2 installed on the remote host is prior to 0.28.9. It is, therefore, affected by multiple vulnerabilities:

  - An out-of-bounds write was found in RemoteIo::Impl::populateBlocks. The bug is in the RemoteIo class, which     is only used when Exiv2 is run on a URL, rather than a local file. (CVE-2026-68546)

  - An out-of-bounds read was found in RemoteIo::Impl::populateBlocks. The bug is in the RemoteIo class, which     is only used when Exiv2 is run on a URL, rather than a local file. (CVE-2026-68547)

  - An out-of-bounds read was found in CrwMap::decodeBasic(). The bug was found by OSS-Fuzz. It is reproducible     with the project's fuzz target, but the maintainers have not been able to reproduce it with the exiv2     command line application. (CVE-2026-49275)

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