"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.");
