    -------------------------------------------------------------------------

    Package        : gnupg2     Version        : 2.2.27-2+deb11u3     CVE ID         : CVE-2025-68973     Debian Bug     : 1124221

    Several issues have been discovered in gnupg2, a tool for secure     communication and data storage.

    CVE-2025-68973

        There exist memory corruptions in the armor parsing code of GnuPG         that can be exploited to provide primitives like out of bounds         buffer read and write. This might be exploitable to the point of         remote code execution (RCE).

    Additional issues:

        + Potential key signature digest algorithm downgrade.

          GnuPG may downgrade the message digest algorithm to insecure SHA1           algorithm during signature checking due to reading from           uninitialized memory. This reduces the security of User ID           Certification Signatures to that of SHA1. SHA1 suffers from known           cryptographic weaknesses like chosen prefix attacks.

        + Multiple plaintext attack on detached PGP signatures.

          An attacker can arbitrarily swap the plaintext shown to a GnuPG           user, when the user verifies a detached signature versus views it           with `--decrypt`. This attack allows deceiving users verifying           messages, following GnuPG usage best practices about the content           of a message signed with a detached signature. Note, that it is           possible in many scenarios to convert between signature types,           i.e., convert a different signature type to a detached signature.

        + GnuPG Accepts Path Separators and Path Traversals in Literal Data.

          GnuPG accepts arbitrary file paths in the unsigned Literal Data           packet filename field and uses that value without sufficient           sanitization. In combination with tricking a user with ANSI           formatted output that changes GnuPG output with deceptive apparent           GnuPG logs, this can lead to creation or overwrite of any file on           the system the user can write to, including executable files which           the user may later execute.

    For Debian 11 bullseye, these problems have been fixed in version     2.2.27-2+deb11u3.

    We recommend that you upgrade your gnupg2 packages.

The version of Tencent Linux installed on the remote TencentOS Server 4 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the TSSA-2026:0002 advisory.

    Package updates are available for TencentOS Server 4 that fix the following vulnerabilities:

    CVE-2025-68973:
    In GnuPG through 2.4.8, 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.)

The remote Ubuntu 16.04 LTS / 18.04 LTS / 20.04 LTS / 22.04 LTS / 24.04 LTS / 25.04 / 25.10 host has packages installed that are affected by a vulnerability as referenced in the USN-7946-1 advisory.

    It was discovered that GnuPG incorrectly handled crafted input. A remote attacker could possibly use this     issue to crash the program, or execute arbitrary code.

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

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.

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

  - 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)

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