The remote CentOS Linux 9 host has a package installed that is affected by a vulnerability as referenced in the opensc-0.23.0-2.el9 build changelog.

  - buffer overrun in pkcs15init for cardos (CVE-2023-2977)

Note that Nessus has not tested for this issue 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.

  - A vulnerbility was found in OpenSC. This security flaw cause a buffer overrun vulnerability in pkcs15     cardos_have_verifyrc_package. The attacker can supply a smart card package with malformed ASN1 context.
    The cardos_have_verifyrc_package function scans the ASN1 buffer for 2 tags, where remaining length is     wrongly caculated due to moved starting pointer. This leads to possible heap-based buffer oob read. In     cases where ASAN is enabled while compiling this causes a crash. Further info leak or more damage is     possible. (CVE-2023-2977)

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

The remote SUSE Linux SLES12 / SLES_SAP12 host has a package installed that is affected by a vulnerability as referenced in the SUSE-SU-2023:2466-1 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 NewStart CGSL host, running version MAIN 7.02, has opensc packages installed that are affected by multiple vulnerabilities:

  - A flaw was found in OpenSC packages that allow a potential PIN bypass. When a token/card is authenticated     by one process, it can perform cryptographic operations in other processes when an empty zero-length pin     is passed. This issue poses a security risk, particularly for OS logon/screen unlock and for small,     permanently connected tokens to computers. Additionally, the token can internally track login status. This     flaw allows an attacker to gain unauthorized access, carry out malicious actions, or compromise the system     without the user's awareness. (CVE-2023-40660)

  - A vulnerbility was found in OpenSC. This security flaw cause a buffer overrun vulnerability in pkcs15     cardos_have_verifyrc_package. The attacker can supply a smart card package with malformed ASN1 context.
    The cardos_have_verifyrc_package function scans the ASN1 buffer for 2 tags, where remaining length is     wrongly caculated due to moved starting pointer. This leads to possible heap-based buffer oob read. In     cases where ASAN is enabled while compiling this causes a crash. Further info leak or more damage is     possible. (CVE-2023-2977)

  - Several memory vulnerabilities were identified within the OpenSC packages, particularly in the card     enrollment process using pkcs15-init when a user or administrator enrolls cards. To take advantage of     these flaws, an attacker must have physical access to the computer system and employ a custom-crafted USB     device or smart card to manipulate responses to APDUs. This manipulation can potentially allow compromise     key generation, certificate loading, and other card management operations during enrollment.
    (CVE-2023-40661)

  - An out-of-bounds read vulnerability was found in OpenSC packages within the MyEID driver when handling     symmetric key encryption. Exploiting this flaw requires an attacker to have physical access to the     computer and a specially crafted USB device or smart card. This flaw allows the attacker to manipulate     APDU responses and potentially gain unauthorized access to sensitive data, compromising the system's     security. (CVE-2023-4535)

  - A vulnerability was found in OpenSC where PKCS#1 encryption padding removal is not implemented as side-     channel resistant. This issue may result in the potential leak of private data. (CVE-2023-5992)

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

リモートの Debian 10 ホストには、dla-3463 のアドバイザリに記載された複数の脆弱性の影響を受けるパッケージがインストールされています。

  - eidenv からの呼び出しによって実証されているように、OpenSC 0.19.0の libopensc の ctx.c の sc_context_create にメモリリークがあります。(CVE-2019-6502)

  - sc_file_valid のバージョン 0.22.0 より前の Opensc でヒープメモリ解放後使用 (Use-After-Free) の問題が見つかりました。(CVE-2021-42779)

  - バージョン 0.22.0 より前の Opensc で、insert_pin 関数のリターン後使用の問題が見つかりました。これにより、ライブラリを使用するプログラムがクラッシュする可能性があります。(CVE-2021-42780)

  - pkcs15-oberthur.c のバージョン0.22.0 より前の Opensc に、ヒープバッファオーバーフローの問題が見つかりました。ライブラリを使用しているプログラムがクラッシュする可能性があります。(CVE-2021-42781)

  - バージョン 0.22.0 より前の Opensc の様々な場所でスタックバッファオーバーフローの問題が見つかりました。これにより、ライブラリを使用するプログラムがクラッシュする可能性があります。(CVE-2021-42782)

  - OpenSC に脆弱性が見つかりました。このセキュリティの欠陥により、pkcs15 cardos_have_verifyrc_package でバッファオーバーランの脆弱性が発生します。攻撃者は、無効な形式の ASN1 コンテキストのあるスマートカードパッケージを提供する可能性があります。
    cardos_have_verifyrc_package 関数は、ASN1 バッファで 2 つのタグをスキャンします。この場合、開始ポインターの移動により、残りの長さが不適切に計算されます。これにより、ヒープベースのバッファ OOB 読み取りが発生する可能性があります。コンパイル中に ASAN が有効な場合、これによりクラッシュが発生します。さらなる情報漏洩や被害が発生する可能性があります。(CVE-2023-2977)
