There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - GnuPG 2.2.21 and 2.2.22 (and Gpg4win 3.1.12) has an array overflow, leading to a crash or possibly
    unspecified other impact, when a victim imports an attacker's OpenPGP key, and this key has AEAD
    preferences. The overflow is caused by a g10/key-check.c error. NOTE: GnuPG 2.3.x is unaffected. GnuPG
    2.2.23 is a fixed version. (CVE-2020-25125)

AEADアルゴリズム用の設定リストを持つOpenPGPキーをインポートすると、配列オーバーフローが発生し、頻繁にクラッシュしたり、他の定義されていない動作が引き起こされます。

多くの場合、攻撃者が任意のキーのインポートを容易に発生させ、このバグを発生させる可能性があります。クラッシュ以外でバグを悪用することは容易なことではありませんが、熱心な攻撃者にとっては可能なことです。
攻撃者にとっての大きなハードルは、1バイトおきに制御され、最初のバイトはすべて0x04の固定値であることです。

Importing an OpenPGP key having a preference list for AEAD algorithms will lead to an array overflow and thus often to a crash or other undefined behaviour.

Importing an arbitrary key can often easily be triggered by an attacker and thus triggering this bug. Exploiting the bug aside from crashes is not trivial but likely possible for a dedicated attacker.
The major hurdle for an attacker is that only every second byte is under their control with every first byte having a fixed value of 0x04.

According to the versions of the gnupg2 package installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - GnuPG 2.2.21 and 2.2.22 (and Gpg4win 3.1.12) has an array overflow, leading to a crash or possibly     unspecified other impact, when a victim imports an attacker's OpenPGP key, and this key has AEAD     preferences.
