In GnuPG through 2.4.8, if a signed message has \f at the end of a plaintext line, an adversary can construct a modified message that places additional text after the signed material, such that signature verification of the modified message succeeds (although an "invalid armor" message is printed during verification). This is related to use of \f as a marker to denote truncation of a long plaintext line.

The remote Fedora 42 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2026-e630ec5c0a advisory.

    New upstream release 2.4.9 fixing several vulnerabilities

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.

The remote Fedora 43 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2026-acea06489d advisory.

    New upstream release 2.4.9 fixing several vulnerabilities

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.

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

  - In GnuPG through 2.4.8, if a signed message has \f at the end of a plaintext line, an adversary can
    construct a modified message that places additional text after the signed material, such that signature
    verification of the modified message succeeds (although an "invalid armor" message is printed during
    verification). This is related to use of \f as a marker to denote truncation of a long plaintext line.
    (CVE-2025-68972)

  - In GnuPG before 2.4.9, armor_filter in g10/armor.c has two increments of an index variable where one is
    intended, leading to an out-of-bounds write for crafted input. (For ExtendedLTS, 2.2.51 and later are
    fixed versions.) (CVE-2025-68973)

The version of gnupg2 installed on the remote host is prior to 2.2.52 / 2.5.16. It is, therefore, affected by multiple vulnerabilities as referenced in the SSA:2025-364-01 advisory.

    New gnupg2 packages are available for Slackware 15.0 and -current to fix security issues.

Tenable has extracted the preceding description block directly from the gnupg2 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.

  - In GnuPG through 2.4.8, if a signed message has \f at the end of a plaintext line, an adversary can     construct a modified message that places additional text after the signed material, such that signature     verification of the modified message succeeds (although an invalid armor message is printed during     verification). This is related to use of \f as a marker to denote truncation of a long plaintext line.
    (CVE-2025-68972)

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